Elixir package to plot data using Python's Matplotlib

Explot

Explot helps you plot your Elixir data using Python's Matplotlib.

This package does not try to redo Matplotlib (have you seen how big is that thing?) but lets Elixir interface with Matplotlib to plot the data.

Installation

def deps do
  [{:explot, "~> 0.1.0"}]
end

Explot needs your system to have installed Python3 and matplotlib. Refer to the official Matplotlib installation guide for details. If you are able to plot with Python, then you are able to plot with Explot.

Usage

Using with Dataframe

Explot is designed to work well with the Dataframe package. Given your data is inside a DataFrame.Frame, you only need to call

DataFrame.plot(frame)

And the DataFrame module will take care of setting up the plot for you and showing it.

Using with your own data

Example session:

iex(1)> plot = Explot.new
#PID<0.116.0>
iex(2)>  Explot.ylabel(plot, "income")
true
iex(3)>  Explot.xlabel(plot, "years")
true
iex(4)> Explot.title(plot, "rich!!")
true
iex(5)> Explot.add_list(plot, [1000, 1500, 2500, 4500, 8500], "$")
true
iex(6)> Explot.x_axis_labels(plot, ["2012", "2013", "2014", "2015", "2016"])
true
iex(7)> Explot.show(plot)
:ok

Will show the following plot:
