# Matplotlib
This library enables to directly call [matplotlib](https://matplotlib.org/) from Ruby language.
This is built on top of [pycall](https://github.com/mrkn/pycall).
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'matplotlib'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install --pre matplotlib
## Usage
### Using pyplot in irb console or standalone scripts
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()
### IRuby integration
`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](examples) to see example usages.
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
## Contributing
Bug reports and pull requests are welcome on GitHub at https://github.com/mrkn/matplotlib.
