This library enables to directly call matplotlib from Ruby language. This is built on top of pycall.
Add this line to your application's Gemfile:
gem 'matplotlib'And then execute:
$ bundle
Or install it yourself as:
$ gem install --pre matplotlib
Example usage:
require 'matplotlib/pyplot'
plt = Matplotlib::Pyplot
xs = [*1..100].map {|x| (x - 50) * Math::PI / 100.0 }
ys = xs.map {|x| Math.sin(x) }
plt.plot(xs, ys)
plt.show()
matplotlib/iruby provides integration between IRuby notebook and matplotlib.
This functionality can be enabled by calling Matplotlib::IRuby.activate.
require 'matplotlib/iruby'
Matplotlib::IRuby.activate
matplotlib/iruby also loads matplotlib/pyplot, so you can use Matplotlib::Pyplot module without explicitly requiring matplotlib/pyplot.
And this introduces a post execution hook which put figures that are created in a cell just below the execution result of the cell.
See ipynb files in examples to see example usages.
