Tutorial 07 — TikZ Backend
TikZ is the de-facto standard for drawing in LaTeX documents.
maxplotlib can render your figures as native TikZ code via the
tikzfigure backend, which wraps the `tikzfigure <https://github.com/max-models/tikzfigure>`__ Python package.This tutorial covers two complementary workflows:
Workflow |
When to use |
|---|---|
Canvas → TikZ |
Quick way to turn data plots into LaTeX-ready TikZ code |
``tikzfigure`` API directly |
Full control — nodes, shapes, annotations, arcs, colours … |
Prerequisites
pip install tikzfigure
To actually render the figure (not just generate code) you also need pdflatex installed on your system.
[1]:
import numpy as np
import tikzfigure as tz
from maxplotlib import Canvas
Part 1 — Canvas → TikZ
The fastest path: build a plot with the standard Canvas API, then pass backend='tikzfigure' to get a TikzFigure object back.
1.1 Basic usage
[2]:
x = np.linspace(0, 2 * np.pi, 60)
canvas = Canvas(width="10cm", ratio=0.6)
canvas.plot(x, np.sin(x), label="sin", color="steelblue", line_width=1.5)
canvas.plot(x, np.cos(x), label="cos", color="tomato", line_width=1.2)
canvas.set_xlabel("x")
canvas.set_ylabel("y")
canvas.set_title("Trigonometric functions")
# backend='tikzfigure' returns a TikzFigure object
tikz = canvas.render(backend="tikzfigure")
print(type(tikz))
<class 'tikzfigure.core.figure.TikzFigure'>
Plotly preview
Before exporting to TikZ, you can preview the same Canvas interactively in a notebook using the Plotly backend:
[3]:
canvas.show(backend="plotly")
Data type cannot be displayed: application/vnd.plotly.v1+json
[4]:
canvas.show(backend="tikzfigure")
warning: The `fitz` API is deprecated and will be removed in future. Use `import pymupdf` instead.
1.2 Inspecting the generated LaTeX
str(tikz) returns the raw LaTeX source string (and generate_tikz() remains available explicitly).Each data line becomes a
\draw command connecting coordinate pairs.[5]:

1.2.1 Checking explicit width and height
When you set both width= and ratio=, the TikZ export now writes explicit pgfplots dimensions. This is useful when you want a tall figure for a column-sized layout in LaTeX.
[6]:
canvas_ratio2, ax_ratio2 = Canvas.subplots(width="10cm", ratio=2)
ax_ratio2.plot(x, np.exp(-x / np.pi), color="purple", line_width=1.5)
ax_ratio2.set_title("ratio = 2 export")
tikz_ratio2 = canvas_ratio2.render(backend="tikzfigure")
ratio2_code = tikz_ratio2.generate_tikz()
for line in ratio2_code.splitlines():
if "nextgroupplot" in line:
print(line.strip())
break
# Expected: width=10cm and height=20cm in the \nextgroupplot options
\nextgroupplot[grid=false, height=20cm, title=ratio = 2 export, axis width=10cm]
1.3 TikZ-specific kwargs
The TikZ backend passes extra keyword arguments straight to
tikzfigure.draw().Use ``line_width=`` (not matplotlib’s
linewidth=) to control stroke thickness.[7]:
canvas2, ax2 = Canvas.subplots(width="10cm", ratio=0.5)
ax2.plot(x, np.sin(x), color="navy", line_width=0.5, label="thin")
ax2.plot(x, np.sin(x) + 0.5, color="steelblue", line_width=1.5, label="medium")
ax2.plot(x, np.sin(x) + 1.0, color="royalblue", line_width=3.0, label="thick")
ax2.set_xlabel("x")
ax2.set_title("Line width comparison")
tikz2 = canvas2.render(backend="tikzfigure")
print(tikz2.generate_tikz())

1.4 Layer-aware TikZ output
Assign data to layers with
layer=N.The TikZ backend respects the layer filter — useful for generating incremental reveal figures (e.g. in Beamer).
[8]:
canvas3, ax3 = Canvas.subplots(width="10cm", ratio=0.55)
ax3.plot(x, np.sin(x), color="steelblue", line_width=1.5, layer=0, label="sin")
ax3.plot(x, np.cos(x), color="tomato", line_width=1.5, layer=1, label="cos")
ax3.plot(
x, np.sin(x) * np.cos(x), color="seagreen", line_width=1.0, layer=2, label="sin·cos"
)
# All layers available on the canvas
print("Available layers:", canvas3.layers)
# Render only layer 0 — one \draw command
tikz_l0 = canvas3.render(backend="tikzfigure", layers=[0])
print("\n--- Layer 0 only ---")
print(f"\\draw count: {tikz_l0.generate_tikz().count(chr(92) + 'draw')}")
# Render layers 0 and 1
tikz_l01 = canvas3.render(backend="tikzfigure", layers=[0, 1])
print("\n--- Layers 0 & 1 ---")
print(f"\\draw count: {tikz_l01.generate_tikz().count(chr(92) + 'draw')}")
Available layers: [0, 1, 2]
--- Layer 0 only ---
\draw count: 0
--- Layers 0 & 1 ---
\draw count: 0
1.5 Saving TikZ code to a file
You can embed the generated code directly in a LaTeX document:
[9]:
tikz_all = canvas3.render(backend="tikzfigure")
with open("figure.tex", "w") as f:
f.write(tikz_all.generate_tikz())
print("Saved figure.tex")
# In your LaTeX document:
# \input{figure.tex}
# or wrap it:
# \begin{figure}[h]
# \centering
# \input{figure.tex}
# \caption{My caption}
# \end{figure}
Saved figure.tex
1.6 Rendering the figure (requires pdflatex)
If pdflatex is installed, tikz.show() compiles the code and opens the PDF:
[10]:
# Requires pdflatex:
tikz_all.show(transparent=False)

For unsupported primitives, the Canvas API raises NotImplementedError; use the direct tikzfigure API for advanced TikZ shapes (Part 2 below).
Part 2 — The tikzfigure API
The tikzfigure package gives you a full Python interface to TikZ primitives. You build figures by adding nodes, paths, shapes, and annotations, then call generate_tikz() (or show()) to obtain the output.
import tikzfigure as tz
tf = tz.TikzFigure()
2.1 Drawing paths with draw()
tf.draw(nodes, ...) produces a \draw path through a list of (x, y) coordinates.
[11]:
tf = tz.TikzFigure()
x = np.linspace(0, 2 * np.pi, 60)
sin_nodes = [(float(xi), float(np.sin(xi))) for xi in x]
cos_nodes = [(float(xi), float(np.cos(xi))) for xi in x]
tf.draw(sin_nodes, color="steelblue", line_width=1.5)
tf.draw(cos_nodes, color="tomato", line_width=1.2)
print(tf.generate_tikz())

2.5 Custom colours with colorlet()
TikZ colour mixing syntax (blue!70!white) lets you define reusable named colours.
[15]:
tf5 = tz.TikzFigure()
# Define named colours
tf5.colorlet("myblue", "blue!70!white")
tf5.colorlet("myred", "red!80!black")
tf5.colorlet("myfill", "blue!10!white")
# Use them in draw calls
tf5.draw(sin_nodes, color="myblue", line_width=1.5)
tf5.draw(cos_nodes, color="myred", line_width=1.5)
# Filled polygon using the fill colour
closed_nodes = sin_nodes + [(float(x[-1]), 0.0), (float(x[0]), 0.0)]
tf5.draw(closed_nodes, fill="myfill", draw="none", cycle=True)
print(tf5.generate_tikz())

The generated code is a standalone
tikzpicture environment.Drop it into any LaTeX document:
\usepackage{tikz}
\begin{figure}[h]

\input{complete_figure.tex}
\caption{Trigonometric functions with shaded region.}

Or compile a standalone PDF with tikzfigure’s generate_standalone() method:
standalone_src = tf_final.generate_standalone()
with open('standalone.tex', 'w') as f:
f.write(standalone_src)
# Then: pdflatex standalone.tex

Part 1.8 — Canvas primitives supported by TikZ
The Canvas TikZ backend supports line, scatter, bar, horizontal-bar, filled-region, and error-bar plots. The following example renders the canvas as TikZ source.

from maxplotlib import Canvas
x = np.arange(5)
y = np.array([1.0, 2.2, 1.4, 3.0, 2.5])

primitive_canvas.plot(x, y, color="black", linewidth=1.5)
primitive_canvas.scatter(x, y + 0.35, color="crimson")
primitive_canvas.bar(x, y * 0.35, color="steelblue", alpha=0.7)
primitive_canvas.fill_between(x, y, 0, color="gold", alpha=0.2)
primitive_canvas.errorbar(x, y, yerr=0.15, color="darkgreen")
primitive_canvas.configure(

The next cell shows the TikZ generated from the canvas. Unsupported primitives now raise NotImplementedError instead of being silently omitted.
Part 1.9 — More TikZ-supported primitives
Step and stairs plots, stems, reference lines, spans, and polygon fills are also translated to TikZ. The generated TikZ is printed below.
