Installation Notes

Install the plugin:

script/plugin install git://github.com/jpemberthy/ezgraphix.git

Run the tasks: (it will move the necessary files to use the plugin)

rake ezgraphix:setup    # run from your project's root 

After the installation include the FusionCharts.js in each layout that will render ezgraphix:

<%= javascript_include_tag "FusionCharts" %>

and that’s it!.

Usage

In your Controller:

For single series charts:

def index
  @g = Ezgraphix::Graphic.new
  @g.data = {:ruby => 1, :perl => 2, :smalltalk => 3}
end

or you can specify the data directly in the constructor:

def index
  @g = Ezgraphix::Graphic.new(:data => {:ruby => 1, :perl => 2, :smalltalk => 3})
end

For multiseries charts:

In this case you have multiple values for each serie. Also you need to specify categories (labels). In the example below there are 2 series “Registrations” and “Payments” and values are divided into 7 months (labels) with a value for each serie/month.

def index
  @g = Ezgraphix::Graphic.new(:c_type => 'mscol3d')
  @g.data = { "Registrations" => [4,2,12,7,0,3,6], "Payments" => [7,3,5,2,1,0,9] }
  @g.labels = ["March", "April", "May", "June", "July", "August", "September"]
end

There are 2 ways to pass render options:

1. When the Graphic object is created, you can define it also as:

@g = Ezgraphix::Graphic.new(:w => 200, :h => 300, :c_type => 'bar3d', :div_name => 'my_chart_tag_name')

The defaults are:

{:c_type => ‘col3d’, :w => 300, :h => 300, :div_name => ’ez_graphic’}

At the moment, you can render the following graphics:

Single Series

Column 2D	=> :c_type => 'col2d'
Column 3D	=> :c_type => 'col3d'
Bar 2D		=> :c_type => 'bar2d'
Pie 2D		=> :c_type => 'pie2d'
Pie 3D		=> :c_type => 'pie3d'
Line		=> :c_type => 'line'
Doughnut 2D	=> :c_type => 'doug2d'

Multi Series

MultiSeriesLine		=> :ctype => 'msline'
MultiSeriesColumn3D	=> :ctype => 'mscol3d'
MultiSeriesColumn2D	=> :ctype => 'mscol2d'
MultiSeriesArea2D	=> :ctype => 'msarea2d'
MultiSeriesBar2D	=> :ctype => 'msbar2d'

2. Anytime you want, by accessing the render_options attribute.

@g.render_options(:caption => 'cool languages', :w => 400)  #Merges new options with the last configuration.

In your view.

Add the following line wherever you want to render the graphic.

<%= render_ezgraphix @g %>

or just

<%= @g %>

Tests

 rake spec	 #run from the plugin's  

Note.

Full set of render_options are specified in the rdoc, and more chart’s support will be included soon!.
