g_flot¶ ↑

github.com/midas/g_flot/tree/master

A Guilded (github.com/midas/guilded/tree/master) Rails component that facilitates creating jQuery Flot graphs.

• Low level wrapper view helper that accepts the same options as the jQuery Flot plugin

sudo gem install midas-g_flot

In Rails environment.rb file:

config.gem 'midas-g_flot', :version => '1.0.0', :lib => 'g_flot', :source => 'http://gems.github.com'

Run the assets generator:

script/generate flot_assets_generator

Simple case (creates a bar graph with 2 bars):

<%= g_flot_graph :id => 'graph', :data => [ { :label => 'One Thing', :data => [[1,10] }, 
      { :label => 'Second Thing', :data => [[2,17] } ] %>

The view helper simply passes through all options to the initialization of the flot graph (the plot method). The view helper uses to_json method to convert the options hash to valid JavaScript syntax. So, for example, an options hash in Ruby:

options = { :id => 'graph', :data => [ { :label => 'One Thing', :data => [[1,10] }, { :label => 'Second Thing', :data => [[2,17] } ] }

In JavaScript would become an object literal:

var options = { id: 'graph', data: [ { label: 'One Thing', data: [[1,10]] }, { label: 'Second Thing', data: [[2,17]] } ] }

See code.google.com/p/flot/ for more infromation about flot and it’s options / functionality.
