Plt Ink — Matplotlib Figures for Inkscape

Overview

Plt Ink embeds a Python/Matplotlib code editor inside Inkscape. Write your figure code, hit render, and the resulting SVG is placed on your canvas as a native, fully editable SVG group — not a rasterised image.

Why native SVG matters

Unlike exporting a PNG from Jupyter and importing it, Plt Ink produces editable SVG: individual lines, bars, and labels are XML elements you can select, recolour, or reposition in Inkscape without going back to Python.

Features

  • Full Python editor with syntax highlighting
  • plt.savefig('__ink__.svg') convention — the extension intercepts the output
  • Figure dimensions automatically matched to selected Inkscape frame
  • Supports numpy, pandas, scipy, matplotlib out of the box

Example

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 2*np.pi, 200)
fig, ax = plt.subplots(figsize=(6, 4))
ax.plot(x, np.sin(x), lw=2, color='#cba6f7')
ax.set_xlabel('Angle (rad)')
ax.set_ylabel('sin(x)')
plt.tight_layout()
