# benchmark-plot

A Ruby benchmark extension to allow comparative plotting of benchmarks.

# Screencast

Watch a screencast of gem usage [here](https://www.youtube.com/watch?v=WW6M4Df-soQ).

# Usage

This gem is mainly useful for benchmarking code over a number of inputs. This input should be supplied in the form of an object capable of calling `#each`.

Sample benchmarking script:

``` ruby

require 'benchmark/plot'

class TestArray

  attr_reader :arr

  def initialize arr

    @arr = arr

  end

  def to_s

    @arr.size.to_s

  end

end

test_data = [5, 25, 50, 75, 100, 125, 150, 175, 200,250,300]

test_data.map! {|e| TestArray.new(Array.new(e) {|i| i}) }

Benchmark.plot(test_data) do |x|

  x.report("map.flatten") do |data|

    data.arr.map { [nil]  }.flatten

  end

  x.report("flat_map") do |data|

    data.arr.flat_map { [nil] }

  end

end

```

Output:
