Jifty::Plugin::Chart::Renderer::SimpleBars - a simple horizontal bar chart
DESCRIPTION
This is a simple renderer for charts created both as a dead simple way of rendering horizontal bar charts, which can be a very simple way
of rendering data, and as a prototype for some other work I'm thinking of doing with the chart plugin.
OPTIONS
Of the rendering API, this only uses the first dataset given and ignores any others. It also fails if used for any type other than the only
one it supports "horizontalbars".
It takes the following options:
summary
To maximize the accessibility of your chart, set this to describe the data. This will set the table's summary attribute.
STYLING
Please be aware that when using this object, you can change the bar color using CSS like so:
div.simple_bars span.bar {
background-color: black;
}
METHODS
init
Tell Jifty about the CSS and JS files SimpleBars needs.
render
Renders a horizontal bar chart. This is done by rendering a table of HTML values, which is then converted to a bar chart by the Javascript
added to the response during "init".
If JavaScript is not supported by the browser, all the data is presented ina table. They can still read the data, but just not in the most
readable form.

Jifty::Plugin::Chart - A charting API for Jifty
SYNOPSIS
In your config.yml:
Plugins:
- Chart: {}
In your Mason templates:
<% Jifty->web->chart(
type => 'Bar',
width => 400,
height => 300,
data => [
[ '2004', '2005', '2006', '2007' ], # labels
[ 14, 15, 17, 22 ], # first data set
[ 22, 25, 20, 21 ], # second data set
],
) %>
DESCRIPTION
CAUTION: This plugin is experimental. The API will change.
This plugin provides a charting API that can be used by Jifty applications to build data visualizations without regard to the underlying
rendering mechanism.
As of this writing, the API is a barely veiled interface over Chart. However, I intend to expand the interface to apply to something like
Maani's XML/SWF Charts or Imprise Javascript charts or even something like OpenLaszlo (or something Open Source and Perl if I can find or
build such a thing in time).
INTERFACE
By adding this method to the plugin configuration for your Jifty application, you will cause Jifty::Web to inherit a new method, "chart",
which is the cornerstone of this API.
This method is described in Jifty::Plugin::Chart::Web and an example is shown in the "SYNOPSIS" above.
CONFIGURATION
Here is an example configuration for config.yml:
Plugins:
- Chart:
DefaultRenderer: PlotKit
PreloadRenderers:
- XMLSWF
- SimpleBars
- App::Renderer::Custom
The available options are:
DefaultRenderer
This is the name of the class to use as the default renderer. Jifty::Plugin::Chart::Renderer::Chart is the current default, but that
could change in the future. It's recommended that you set this to your preference.
PreloadRenderers
This is a list of other render classes to load during initialization. If they are not loaded during initialization some renderers may
not work correctly the first time they are run because they are not able to inform Jifty of the CSS or JS files they need before that
part of the page is already rendered. If you use the "renderer" option of "chart" in Jifty::Plugin::Chart::Web, then you should make
sure any value you use is set here in the configuration to make sure it works properly.
METHODS
init
Adds the "chart" in Jifty::Plugin::Chart::Web method to Jifty::Web.
init_renderer
my $renderer = $chart_plugin->init_renderer($renderer_class)
This is a helper method that is used by the API to initialize the renderer class. This is handled automatically so you probably shouldn't
use this.
