Goals

The goal is to have a very simple plotting library for 2d line plots, with an api modeled after matlab and matplotlib.

Target

The reference style will be matplotlib-like, a goal is to be able to produce something matching:

PNG:

SVG:

Those are produced by

import matplotlib.pyplot as pp
import numpy as np
x = np.arange(0.0,10,0.1)
y1 = np.sin(x)
y2 = np.cos(x)
fig, ax = pp.subplots()
ax.plot(x,y1,x,y2)
ax.grid()
fig.savefig("targetpng.png")
fig.savefig("targetsvg.svg")

Current

Currently we have:

PNG:

SVG:

with:

import graph, math, arraymancer
let 
  x  = arange(0.0'f64, 10,0.1)
let 
  y  = sin(x)
  y2 = cos(x)
var srf = plot(x.data,y.data)
srf.plot(x.data, y2.data)
srf.grid
# Save to file
srf.saveTo("currentpng.png")
srf.saveTo("currentsvg.svg")
