And excute with dub run --single. For more details, please refer to the documentation of dub.

Syntax

Most pyplot functions are avilable. For more details for each functions, please refer to the documantation of pyplot. Describe Python keyword arguments as an associative array with string of keyword name as key.

  • The Python way: function(arg1, arg2..., keyword1=kwarg1, keyword2=kwarg2...)
  • The D way: function(arg1, arg2..., ["keyword1": kwarg1], ["keyword2": kwarg2])

Examples

Simple example:

import std.math;
import std.range;
import std.algorithm;
import plt = matplotlibd.pyplot;

void main() {
	auto x = iota(0, 2.05, 0.05).map!(x => x * PI);
	auto y = x.map!(sin);

	plt.plot(x, y, "r-", ["label": "$y=sin(x)$"]);
	plt.xlim(0, 2 * PI);
	plt.ylim(-1, 1);
	plt.legend();
	plt.savefig("simple.png");
	plt.clear();
}

Simple example

Color plot example:

import std.range;
import plt = matplotlibd.pyplot;

void main() {
	const n = 100;
	auto x = iota(n);
	auto y = x[];
	double[n][n] z;
		
	foreach (i; 0..n)
		foreach (j; 0..n)
			z[i][j] = i + j;
	    
	plt.contourf(x, y, z, 64, ["cmap": "hsv"]);
	plt.colorbar();
	plt.savefig("color.png");
	plt.clear();
}
