Charting/graphing extensions for the Ratistics statistics gem
Ratistics Charts is an extension to the Ratistics library for statistics and statistical computing. It adds data visualization through simple charting and graphing. It is intended to work with that library specifically but is general enough it may be useful with data generated from other sources. Ratistics Charts is not intended to be a full-featured data visualization solution. It is intended to provide simple charting/graphing convenience functions only.
Ratistics is pronounced ra-TIS-tics. Just like "statistics" but with an 'R'
"Statistics".gsub(/^St/i, 'R') #=> "Ratistics"
The project is hosted on the following sites:
- RubyGems project page
- Source code on GitHub
- YARD documentation on RubyDoc.org
- Continuous integration on Travis-CI
- Dependency tracking on Gemnasium
- Follow me on Twitter
See the changelog for information on the latest updates.
This library is intended to solve a small but powerful set of use cases related to data visualization in statistical computing. As much as possible the project is designed to achieve the following goals:
- Be simple and easy to use
- Provide an API consistent with Ratistics
- Maintain an internally-consistent set of conventions with reasonable defaults
- Work directly against data and data structures produced by Ratistics functions
- Hide the details of the underlying charting/graphing/image processing libraries
Because simplicity is a key goal, much of the power of the underlying charting/graphing/image libraries will not be exposed. If Ratistics Charts proves too limited for your needs I recommend working directly with one of the many full-features Ruby data visualization solutions.
Install from RubyGems:
gem install ratistics-charts
or add the following line to Gemfile:
and run bundle install from your shell.
Require Ratistics within your Ruby project:
then use it:
sample = [2, 3, 4, 5, 6] Ratistics::Chart.simple_line_graph('Chart Title', sample) #=> chart_title.png 400x300 DirectClass 16-bit 16kb
