TikzPlot

A clean version of PltToTikz, this time as Python package. Easy to use: only replace import matplotlib.pyplot with this library.

Please let me know if you find any bugs or unexpected behaviour. Examples may be found in repository under tests/ directory.

Installation

NEW: PyPI: pip install tikzplot42. Alternativley, download this package and install using: pip install [path], where [path] is the path to the directory, containing pyproject.toml.

Python usage

Instead of using import matplotlib.pyplot (as plt), use import tikzplot.plots (as plt).

LaTeX requirements

• \usepackage{tikz},
• \usepackage{pgfplots},
• \pgfplotsset{compat=1.18} (may be lower, but compilation is not guaranteed),
• \usepgfplotslibrary{fillbetween} (if you use fill-between plots),
• \usepgfplotslibrary{groupplots} (recommended for best results, enabled by default, may be avoided by setting TikzConfig USE_GROUPPLOTS=False),
• \usepackage{xcolor} (recommended for best colors, works without but needs change of TikzConfig USE_XCOLOR=False),
• \usepgfplotslibrary{polar} required for polar axis.

Export using plt.savefig("example_graph.tex") (recommended) or plt.show(). Then use the generated file as \input{example_graph.tex}.

Currently implemented:

Some basic plot commands are already implemented with commonly used arguments:

Plotting

• plot(),
• scatter(),
• loglog(),
• semilogx()/semilogy(),
• errorbar(),
• stem(),
• fill_between(),
• hlines()/vlines(),
• histogram(),
• step(),
• imshow(),
• text(),
• magnify() (used to magnify part of a plot, but Tikz cannot handle fill_between if this one is used, which is a long known issue),
• axvline()/axhline(),
• axvspan()/axhspan() (background span).

Figures

• plt.figure() (currently only to give you figure object or to set figsize),
• plt.subplot(), plt.subplots() (with sharex/sharey fully implemented, projection polar and 3d with basic support),
• set_size_inches(),
• delaxes().

Styles

If axes and plot have different name for command with same effect, both are implemented (e.g. plt.xlim() and ax.set_xlim()).

• grid(),
• xlabel()/ylabel(),
• xlim(), ylim(),
• xscale("log")/yscale("log"),
• xticks()/yticks(),
• ax.set_xticklabels()/ax.set_yticklabels(),
• legend() (basic position control),
• ax.twinx(),
• ax.set().

There is a limited support for built-in styles (e.g. plt.style.use("default")), you may also define your own style using plt.style.set_profile(). Currently supported features are: color cycle (hex colors sequence), line width (in pt), grid (with matplotlib kwargs), background (latex style key=value), additional settings (raw latex code for optional arguments to axis: key=value).

Supported common **kwargs

• color/c (all matplotlib formats, except color schemes which are not yet implemented),
• linestyle/ls,
• linewidth/ls,
• fmt,
• marker,
• marksize/ms,
• alpha,
• label.

Colorbars

Colorbars and colormaps are implemented a bit differently than in matplotlib (simplified):

• if you use imshow(), you may use its return in Colorbar() (which you have to import as from tikzplot import Colorbar),
• you may use Colorbar(axis, cmap, lower, upper, ...) for manual colorbar. Additional kwargs may also be used by imshow() return,
• note that only one colorbar/colormap per axis is allowed (also if you use scatter with colormap/colorbar).

TikzConfig

For plot configurations (default sizes, paddings, etc.), use from tikzplot import TikzConfig:

• modifyParam(PARAM=value) (for runtime session setting),
• setPermanent(PARAM=value) (for user defined default value). Currently supported parameters are listed with their default values in src/tikzplot/config.py.

More features coming soon...

• more developed styles,
• improved 3D plots (currently only basic support: plot, errorbar, fill_between, scatter, plot_wireframe, plot_surface),
• ...
