AquaPlot is a data visualization library for crystal-lang. It provides an easy to user interface to create visually appealing charts. This project is currently in extremely unstable and active development. Contributions are both welcomed and encouraged, to get this library to a stable and useful state.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     aquaplot:
       github: crystal-data/aquaplot

2. Run shards install

Usage

Gnuplot is required. Please review your operating system's installation instructions to install the library.

Function Charts

fns = ["sin(x)", "cos(x)", "tan(x)", "atan(x)", "asin(x)"].map do |fn|
  AquaPlot::Function.new fn
end

plt = AquaPlot::Plot.new fns
plt.show
plt.close

3D Function Charts

fns = ["x**2 + y**2", "x**2 - y**2", "x**2 * y**2", "x**2 / y**2"].map do |fn|
  AquaPlot::Function.new fn
end

plt = AquaPlot::Plot3D.new fns
plt.set_key("left box")
plt.show
plt.close

2D Line Charts

lines = (1...5).map do |n|
  AquaPlot::Line.new (0...10).map { |el| Random.rand(50) }, title: "Line #{n}"
end

lines[0].show_points
lines[1].set_linewidth 1

plt = AquaPlot::Plot.new lines

plt.set_title("Showing Some Options")

plt.show
plt.close
