Description
-----------
This repo is the continuation of the original [SVG::Graph library](http://www.germane-software.com/software/SVG/SVG::Graph/) by Sean Russell. I'd like to thank Claudio Bustos for giving me permissions to continue publishing the gem under it's original name: [svg-graph](https://rubygems.org/gems/svg-graph)
[Changelog](../master/History.txt)
I'm maintaing in my free time, so I can't promise on any deadlines. Please notify me (via github messages or on the Issues section) if you find any bug.
Contribute
-----
Pull requests are very welcome :-)
Usage
-----
For a complete list of configuration options please have a look at the source - most important [Graph.rb](../master/lib/SVG/Graph/Graph.rb), also checkout the subclasses (Pie, Bar, etc.) as they might provide additional options.
You can require everything at once
```ruby
require 'svggraph'
```
or only the individual parts you need
```ruby
require 'SVG/Graph/Bar'
require 'SVG/Graph/Line'
...
```
In the following some examples to get you up to speed.
### Bar
```ruby
require 'SVG/Graph/Bar'
x_axis = ['1-10', '10-30', '30-50', '50-70', 'older']
options = {
:width => 640,
:height => 300,
:stack => :side, # the stack option is valid for Bar graphs only
:fields => x_axis,
:graph_title => "kg per head and year chocolate consumption",
:show_graph_title => true,
:show_x_title => true,
:x_title => 'Age in years',
:show_y_title => true,
:y_title => 'kg/year',
:y_title_location => :end,
:no_css => true
}
male_data = [2, 4, 6, 4, 2]
female_data = [1, 5, 4, 5, 2.7]
g = SVG::Graph::Bar.new(options)
g.add_data( {
:data => female_data,
:title => "Female"
})
g.add_data( {
:data => male_data,
:title => "Male"
})
# graph.burn # this returns a full valid xml document containing the graph
# graph.burn_svg_only # this only returns the <svg>...</svg> node
File.open('bar.svg', 'w') {|f| f.write(g.burn_svg_only)}
```
