Overview

“Rindow Math Plot” is a visualization library for mathematical data.

It is made to resemble python matplotlib to save time for many people to learn.

It has the following features.

• Visualize data as it is on bar graphs and line graphs
  • The graph types are line, bar, horizontal bar, dot, circle, color bar etc.

$ composer require rindow/rindow-math-plot

Add extension configuration to php.ini

extension=gd2
or
extension=gd

In the case of Linux, explicitly set the viewer that displays png in the environment variable.

RINDOW_MATH_PLOT_VIEWER=/some/tool/pngviewer
export RINDOW_MATH_PLOT_VIEWER

Quickstart

Displays a simple graph.

$mo = new Rindow\Math\Matrix\MatrixOperator();
$plt = new Rindow\Math\Plot\Plot(null,$mo);
$x = $mo->op($mo->arange(10),'**',2);
$plt->plot($x);
$plt->show();
