This is ***a patched version of*** tikzplotlib, a Python tool for converting matplotlib figures into
[PGFPlots](https://www.ctan.org/pkg/pgfplots) ([PGF/TikZ](https://www.ctan.org/pkg/pgf))
figures like

![](https://nschloe.github.io/tikzplotlib/example.png)

for native inclusion into LaTeX or ConTeXt documents.

This version contains patches from [`JasonGross/tikzplotlib/patched`](https://github.com/JasonGross/tikzplotlib/tree/patched).

The output of tikzplotlib is in [PGFPlots](https://github.com/pgf-tikz/pgfplots/), a TeX
library that sits on top of [PGF/TikZ](https://en.wikipedia.org/wiki/PGF/TikZ) and
describes graphs in terms of axes, data etc. Consequently, the output of tikzplotlib

-   retains more information,
-   can be more easily understood, and
-   is more easily editable

than [raw TikZ output](https://matplotlib.org/users/whats_new.html#pgf-tikz-backend).
For example, the matplotlib figure

```python
import matplotlib.pyplot as plt
import numpy as np

plt.style.use("ggplot")

t = np.arange(0.0, 2.0, 0.1)
s = np.sin(2 * np.pi * t)
s2 = np.cos(2 * np.pi * t)
plt.plot(t, s, "o-", lw=4.1)
plt.plot(t, s2, "o-", lw=4.1)
plt.xlabel("time (s)")
plt.ylabel("Voltage (mV)")
plt.title("Simple plot $\\frac{\\alpha}{2}$")
plt.grid(True)

import tikzplotlib

tikzplotlib.save("test.tex")
```

<!--close the figure and reset defaults
<!--pytest-codeblocks:cont-->

```python
import matplotlib as mpl

plt.close()
mpl.rcParams.update(mpl.rcParamsDefault)
```

-->
(see above) gives

```latex
\begin{tikzpicture}

\definecolor{color0}{rgb}{0.886274509803922,0.290196078431373,0.2}

\end{axis}

\end{tikzpicture}
```

(Use `get_tikz_code()` instead of `save()` if you want the code as a string.)

Tweaking the plot is straightforward and can be done as part of your TeX work flow.
[The fantastic PGFPlots manual](http://pgfplots.sourceforge.net/pgfplots.pdf) contains
great examples of how to make your plot look even better.

Of course, not all figures produced by matplotlib can be converted without error.
Notably, [3D plots don't work](https://github.com/matplotlib/matplotlib/issues/7243).

### Installation

tikzplotlib is [available from the Python Package
Index](https://pypi.org/project/tikzplotlib/), so simply do

```
pip install tikzplotlib
```

to install.

### Usage

1. Generate your matplotlib plot as usual.

2. Instead of `pyplot.show()`, invoke tikzplotlib by

    ```python
    import tikzplotlib

    tikzplotlib.save("mytikz.tex")
    # or
    tikzplotlib.save("mytikz.tex", flavor="context")
    ```

    to store the TikZ file as `mytikz.tex`.

3. Add the contents of `mytikz.tex` into your TeX source code. A convenient way of doing
   so is via

    ```latex
    \input{/path/to/mytikz.tex}
    ```

    Also make sure that the packages for PGFPlots and proper Unicode support and are
    included in the header of your document:

    ```latex
    \usepackage[utf8]{inputenc}
    \usepackage{pgfplots}
    \DeclareUnicodeCharacter{2212}{−}
    \usepgfplotslibrary{groupplots,dateplot}
    \usetikzlibrary{patterns,shapes.arrows}
    \pgfplotsset{compat=newest}
    ```

    or:

    ```latex
    \setupcolors[state=start]
    \usemodule[tikz]
    \usemodule[pgfplots]
    \usepgfplotslibrary[groupplots,dateplot]
    \usetikzlibrary[patterns,shapes.arrows]
    \pgfplotsset{compat=newest}
    \unexpanded\def\startgroupplot{\groupplot}
    \unexpanded\def\stopgroupplot{\endgroupplot}
    ```

    You can also get the code via:

    ```python
    import tikzplotlib

    tikzplotlib.Flavors.latex.preamble()
    # or
    tikzplotlib.Flavors.context.preamble()
    ```

4. [Optional] Clean up the figure before exporting to tikz using the `clean_figure`
   command.

    ```python
    import matplotlib.pyplot as plt
    import numpy as np

    # ... do your plotting

    import tikzplotlib

    tikzplotlib.clean_figure()
    tikzplotlib.save("test.tex")
    ```

    The command will remove points that are outside the axes limits, simplify curves and
    reduce point density for the specified target resolution.

    The feature originated from the
    [matlab2tikz](https://github.com/matlab2tikz/matlab2tikz) project and is adapted to
    matplotlib.

### Contributing

If you experience bugs, would like to contribute, have nice examples of what tikzplotlib
can do, or if you are just looking for more information, then please visit
[tikzplotlib's GitHub page](https://github.com/nschloe/tikzplotlib).

### Testing

tikzplotlib has automatic unit testing to make sure that the software doesn't
accidentally get worse over time. In `test/`, a number of test cases are specified.
Those run through tikzplotlib and compare the output with a previously stored reference
TeX file.

To run the tests, just check out this repository and type

```
pytest
```
