plottr

Plottr

Plottr will generate a scatter plot as a string based on the coordinates you pass in. Print string to see the scatter plot in all its glory.

Plottr.plot(<array of [x,y] type coordinate arrays>) (generates new array of arrays (graph) with given points)

Installation

Add this line to your application's Gemfile:

gem 'plottr'

And then execute:

$ bundle

Or install it yourself as:

$ gem install plottr

Usage

Pass in an array of [x,y] coordinates (see plottr_test.rb file for examples) to Scatter class and use gen_string_scatter_plot method to generate a string which will print out as a scatter plot with your coordinate points on it.

Example usage

plottr_scatter = Plottr::Scatter.new(<array of coordinate arrays>)

string_scatter_plot = plottr_scatter.gen_string_scatter_plot

print string_scatter_plot

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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.

TODO:

• allow users to add points (with higher x or y values than max from last points) to a graph thats already been created (plottr = Plottr.new, plottr.plot([0,0], [1,0]), plottr.plot([5,0], [9,8]))
• add statistics on graph
• allow average line through graph (will have to completely change it!)
