Title: jqPlot Readme
Pure JavaScript plotting plugin for jQuery.
To learn how to use jqPlot, start with the Basic Unsage Instructions below. Then read the
usage.txt and jqPlotOptions.txt files included with the distribution.
The jqPlot home page is at <http://www.jqplot.com/>.
Downloads can be found at <http://bitbucket.org/cleonello/jqplot/downloads/>.
The mailing list is at <http://groups.google.com/group/jqplot-users>.
Examples and unit tests are at <http://www.jqplot.com/tests/>.
Documentation is at <http://www.jqplot.com/docs/>.
The project page and source code are at <http://www.bitbucket.org/cleonello/jqplot/>.
Bugs, issues, feature requests: <http://www.bitbucket.org/cleonello/jqplot/issues/>.
Basic Usage Instructions:
jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.4 is included in
the distribution. To use jqPlot include jQuery, the jqPlot jQuery plugin, the jqPlot css file and
optionally the excanvas script to support IE version prior to IE 9 in your web page:
> <!--[if lt IE 9]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
> <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script>
> <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
> <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
For usage instructions, see <jqPlot Usage> in usage.txt. For available options, see
<jqPlot Options> in jqPlotOptions.txt.
Building from source:
If you've cloned the repository, you can build a distribution from source.
You need to have ant <http://ant.apache.org> installed. You can simply
type "ant" from the jqplot directory to build the default "all" target.
There are 6 pertinent targets: clean, dist, min, docs, compress and all. Use:
> ant -p
to get a description of the various build targets.

0.9.5.1:
* Fixed bug where tooltip not working with OHLC and candlestick charts.
* Added additional marker styles: plus, X and dash.
0.9.5:
* Implemented "zoomProxy". zoomProxy allows zooming one plot from another
such as an overview plot.
* Zooming can now be constrained to just x or y axis.
* Enhanced cursor plugin with vertical "dataTracking" line. This is a line
at the cursor location with a readout of data points at the line location
which are displayed in the chart legend.
* Changed cursor tooltip format string. Now one format string is used for
entire tooltip.
* Added mechanisms to specify plot size when plot target is hidden or plot
height/width otherwise cannot be determined from markup.
* Added $.jqplot.config object to specify jqplot wide configuration options.
These include enablePlugins to globally set the default plugin state on/off
and defaultHeight/defaultWidth to specify default plot height/width.
* Added fillToZero option which forces filled charts to fill to zero as opposed
to axis minimum. Thus negative filled bar/line values will fill upwards to
zero axis value.
* Added option to disable stacking on individual lines.
* Changed targetId property of the plot object so it now includes a "#" before
the id string.
* Improved tick and body sizing of Open Hi Low Close and candlestick charts.
* Removed lots of web site related files from the repository. This means that,
if working from the sources, user's won't be able to build the jqplot web
site and the docs/tests that are hosted on that site. The minified and
compressed distribution packages will build fine.
* Lots of examples were added to a separate examples directory to better show
functionality of jqPlot for local testing with the distribution.
* Many various bug fixes and other minor enhancements.
0.9.4:
* Implemented axis labels. Labels can be rendered in div tags or as canvas
elements supporting rotated text.

* Fixed undesirable behavior where point labels for points off the plot
were being rendered.
* Added edgeTolerance option to point label renderer to control rendering of
labels near plot edges.
0.9.3:
* Preliminary support for axis labels. Currently rendered into DIV tags,
so no rotated label support. This feature is currently experimental.
* Fixed bug #52, needed space in tick div tag between style and class declarations
or plot failed in certain application doctypes.
* Fixed issue #54, miter style line join for chart lines causing spikes at steep
changes in slope. Changed miter style to round.
* Added examples for new autoscaling algorithm.
* Fixed bug #57, category axis labels disappear on redraw()
* Improved algorithm which controlled maximum number of labels that would display
on a category axis.
* Fixed bug #45 where null values causing errors in plotData and gridData.
* Fixed issue #60 where seriesColors option was not working.
0.9.2:
* Fixed bug #45 where a plot could crash if series had different numbers of points.
* Fixed issue #50, added option to turn off sorting of series data.

0.9.1:
* Fixed bug #40, when axis pad, padMax, padMin set to 0, graph would fail to render.
* Fixed bug #41 where pie and bar charts not rendered correctly on redraw().

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

Title: Options Tutorial
This document will help you understand how jqPlot's options
relate to the API documentation and the jqPlot object
itself. For a listing of options available to jqPlot,
see <jqPlot Options> in the jqPlotOptions.txt file.
The key to effectively using jqPlot is understanding jqPlot's
options. The online documentation is API documentation. While
it explains what attributes and methods various objects posses,
it doesn't explain how to use or set those attributes through
options. This tutorial will help explain that.
Lets assume you are creating a plot
like this:
> chart = $.jqplot('chart', dataSeries, optionsObj);
First, note that you shouldn't try to directly set attributes on the
"chart" object (like chart.grid.shadow) after your call to $.jqplot().
At best this won't do anything **(see below). You should pass options in via
the "optionsObj".
the optionsObj really represents the plot object (jqPlot object, not
to be confused with the $.jqplot function which will create a jqPlot
object). Attributes you specify on that object will be merged with
attributes in the jqPlot object. The axes, legend, series, etc. are
attributes on the jqPlot object. The jqPlot/optionsObj object looks
something like (only some attributes shown):
> jqPlot-|
> |-seriesColors
> |-textColor
> |-fontFamily
> |-fontSize
> |-stackSeries
> |-series(Array)-|
> | |-Series1-|
> | | |-lineWidth
> | | |-shadow
> | | |-showLine
> | | |-showMarker
> | | |-color
> | |-Series2...
> | |-...
> | |-SeriesN
> |
> |-grid(Object)-|
> | |-drawGridLines
> | |-background
> | |-borderColor
> | |-borderWidth
> | |-shadow
> |
> |-title(Object)-|
> | |-text
> | |-show
> | |-fontFamily
> | |-fontSize
> | |-textAlign
> | |-textColor
> |
> |-axes(Object)-|
> | |-xais-|
> | | |-min
> | | |-max
> | | |-numberTicks
> | | |-showTicks
> | | |-showTickMarks
> | | |-pad
> |
> | ... and so on
The optionsObj should follow the same construction as if it were a
jqPlot object (with some exceptions/shortcuts I'll mention in a
moment). So generally, when you see something like
"this.drawGridLines" in the grid properties in the docs, just replace
"this" with "grid" in your options object. So it becomes
optionsObj.grid.drawGridLines. Do likewise with the other objects in
the plot, replacing "this", with the respective attribute on the plot
like "legend" or "title". Series and Axes are handled a little
different, because series is an array and axes has 4 distinct children
"xaxis", "yaxis", "x2axis" and "y2axis".
So, to remove the shadow from the grid and change the grid border size
you would do:
> optionObj = {grid:{shadow:false, borderWidth:9.0}};
To do the same as above but also make all the text in the plot red you
would do:
> optionObj = {
> textColor:"#ff0000",
> grid:{shadow:false, borderWidth:9.0}
> }
Here is a more deeply nested example. Say you want to specify a min
and max on your y axis and use a specific color for your second
series. That would look like:
> optionsObj = {
> axes:{yaxis:{min:5, max:230}},
> series:[{},{color:"#33ff66"}]
> }
Note that series options are an array in order of the series data you
sent in to your plot. To get to the second series, you have to put an
object (even if empty) in place of the first series.
There is a handy shortcut to assign options to all axes or all series
at one go. Use axesDefaults and seriesDefaults. So, if you wanted
both x and y axes to start at 0 and you wanted all series to not show
markers, you could do:
> optionsObj = {axesDefaults:{min:0}, seriesDefaults:{showMarker:false}}
Another shortcut is for the plot title. Normally, you would assign
options to the title as an object. If you specify a title option as a
string, it will assign that to the title.text property automatically.
So these two are equivalent:
> optionsObj = {title:{text:"My Plot"}}
and
> optionsObj = {title:"My Plot"}
Where things need more explaination is with renderers, plugins and
their options. Briefly, what's renderer, what's a plugin.
A renderer is an object that is used to draw something and gets
attached to an existing object in the plot in order to draw it. A
plugin does more than just provide drawing functionality to an
object. It will do more like calculate a trend line, change the
cursor, provide event driven functionality, etc. I consider renderers
plugins, but plugins don't have to be renderers.
So, how do you use renderers, plugins, and specify their options?
Some common renderes are for bar charts and category axes. If you
want to render your series as a bar chart with each set of bars
showing up in a category on the x axis, you do:
> optionsObj = {
> seriesDefaults:{renderer:$.jqplot.BarRenderer},
> axes:{xaxis:{renderer:$.jqplot.CategoryAxisRenderer}}
> }
This replaces the default renderer used for all series in the plot
with a bar renderer and the x axis default renderer (but not any other
axis) with a category renderer.
Now, how would I assign options to those renderers? The renderer's
attributes may not be present in the pre-existing jqPlot object, they
may be specific to the renderer. This is done through the
"rendererOptions" option on the appropriate object. So, if I wanted my
bars to be 25 pixels wide, I would do:
> optionsObj = {
> seriesDefaults:{
> renderer:$.jqplot.BarRenderer},
> rendererOptions:{
> barWidth:25
> },
> axes:{xaxis:{renderer:$.jqplot.CategoryAxisRenderer}}
> }
Again, this is using the "seriesDefaults" option, which will apply
options to all series in the plot. You could do the same on any
particular series in the plot through the "series" options array.
Plugins are free to add their own options. For example, the
highlighter plugin has it's own set of options that are unique to it.
As a result, it responds to options placed in the "highlighter"
attribute of your options object. So, if I wanted to change the
highlighter tooltip to fade in and out slowly and be positioned
directly above the point I'm highlighting:
> optionsObj = {
> highlighter:{tooltipFadeSpeed:'slow', tooltipLocation:'n'}
> }
Other plugins, like dragable and trendlines, add their options in with
the series. This is because both of those plugins can have different
options for different series in the plot. So, if you wanted to specify the
color of the dragable and constrain it to drag only on the x axis as well
as specify the color of the trend line you could do:
> series:[{
> dragable: {
> color: '#ff3366',
> constrainTo: 'x'
> },
> trendline: {
> color: '#cccccc'
> }
> }]
This would apply those options to the first series only. If you had 2 series
and wanted to turn off dragging and trend lines on the second series, you could do:
> series:[{
> dragable: {
> color: '#ff3366',
> constrainTo: 'x'
> },
> trendline: {
> color: '#cccccc'
> }
> }, {
> isDragable: false,
> trendline:{
> show: false
> }
> }]
Note, series dragability is turned off with the "isDragable" option directly on
the series itself, not with a suboption of "dragable". This may be improved
in the future.
I hope this is helpful.
A few key points to remember:
- When you see "this" in the api docs, you generally replace it with
the name of the object (in lowercase) you are looking at in your
options object.
- seriesDefaults and axesDefaults are convenient shortcuts.
- to assign options to a renderer, generally use the "rendererOptions"
- plugins may add their own options attribute, like "highlighter" or
"cursor".
** Note: you can set attributes after the plot is created (like
plot.grid.shadow = false), but you'll have to issue the appropriate
calls to possibly reinitialize and redraw the plot. jqPlot can
definitely handle this to change the plot after creation (this is how
the dragable plugin updates the plot data and the trend line plugin
recomputes itself when data changes). This hasn't been documented
yet, however.

Title: jqPlot Usage
Usage Documentation:
Introduction:
jqPlot is a jQuery plugin to generate pure client-side javascript charts in your web pages.
The jqPlot home page is at <http://www.jqplot.com/>.
The project page and downloads are at <http://www.bitbucket.org/cleonello/jqplot/>.
Below are a few examples to demonstrate jqPlot usage. These plots are shown as static images.
Many more examples of dynamically rendered plots can be seen on the test and examples pages here: <../../tests/>.
Include the Files:
jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.4 is included in the distribution.
To use jqPlot include jquery, the jqPlot jQuery plugin, jqPlot css file and optionally the excanvas
script for IE support in your web page. Note, excanvas is required only for IE versions below 9. IE 9 includes
native support for the canvas element and does not require excanvas:
> <!--[if lt IE 9]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
> <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script>
> <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
> <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
Add a plot container:
Add a container (target) to your web page where you want your plot to show up.
Be sure to give your target a width and a height:
> <div id="chartdiv" style="height:400px;width:300px; "></div>
Create a plot:
Then, create the actual plot by calling the
$.jqplot plugin with the id of your target and some data:
> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]);
Which will produce a
chart like:
(see images/basicline.png)
Plot Options:
You can customize the plot by passing options to the $.jqplot function. Options are described in
<jqPlot Options> in the jqPlotOptions.txt file. An example of options usage:
> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
> { title:'Exponential Line',
> axes:{yaxis:{min:-10, max:240}},
> series:[{color:'#5FAB78'}]
> });
Which will produce
a plot like:
(see images/basicoptions.png)
Using Plugins:
You can use jqPlot plugins (that is, plugins to the jqPlot plugin) by including them in your html
after you include the jqPlot plugin. Here is how to include the log axis plugin:
> <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
> <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
> <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script>
> <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
> <script language="javascript" type="text/javascript" src="jqplot.logAxisRenderer.js"></script>
Important note: For jqplot builds r529 and above (0.9.7r529 and higher), you must explicitly
enable plugins via either the { show: true } plugin option to the plot or by using
the $.jqplot.config.enablePlugins = true; config options set on the page before plot creation.
Only plugins that can be immediately active upon loading are affected. This includes
non-renderer plugins like cursor, dragable, highlighter, and trendline.
Here is a the same $.jqplot call
but with a log y axis:
> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
> { title:'Exponential Line',
> axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer}},
> series:[{color:'#5FAB78'}]
> });
Which produces
a plot like:
(see images/basiclogaxis.png)
You can further customize with options specific
to the log axis plugin:
> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]],
> { title:'Exponential Line',
> axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer, tickDistribution:'power'}},
> series:[{color:'#5FAB78'}]
> });
Which makes a
plot like:
(see images/basiclogoptions.png)
For a full list of options, see <jqPlot Options> in the jqPlotOptions.txt file.
You can add as many plugins as you wish. Order is generally not important.
Some plugins, like the highlighter plugin which highlights data points near the
mouse, don't need any extra options or setup to function. Highlighter does have
additional options which the user can set.
Other plugins, the barRenderer for example, provide functionality the must be specified
in the chart options object. To render a series as a bar graph with the bar renderer,
you would first include the plugin after jqPlot:
> <script language="javascript" type="text/javascript" src="plugins/jqplot.barRenderer.min.js"></script>
Then you would create
a chart like:
> $.jqplot('chartdiv', [[34.53, 56.32, 25.1, 18.6]], {series:[{renderer:$.jqplot.BarRenderer}]});
Here the default LineRenderer is replaced by a BarRenderer to generate a bar graph for the first (an only) series.
