This is matplotlib2tikz, a Python tool for converting matplotlib figures into
[PGFPlots](https://www.ctan.org/pkg/pgfplots)
([TikZ](https://www.ctan.org/pkg/pgf)) figures like

![](https://nschloe.github.io/matplotlib2tikz/example.png)

for native inclusion into LaTeX documents.

The output of matplotlib2tikz is in
[PGFPlots](http://pgfplots.sourceforge.net/pgfplots.pdf), a LaTeX library that
sits on top of TikZ and describes graphs in terms of axes, data etc.
Consequently, the output of matplotlib2tikz 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,test
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)

from matplotlib2tikz import save as tikz_save

tikz_save("test.tex")
```
(see above) gives
```latex

\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 LaTeX
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 plot don't work](https://github.com/matplotlib/matplotlib/issues/7243).

### Installation

matplotlib2tikz is [available from the Python Package
Index](https://pypi.org/project/matplotlib2tikz/), so
simply type
```
pip install -U matplotlib2tikz
```
to install/update.


### Usage

1. Generate your matplotlib plot as usual.

2. Instead of `pyplot.show()`, invoke matplotlib2tikz by
    ```python
    tikz_save('mytikz.tex')
    ```
   to store the TikZ file as `mytikz.tex`. Load the library with:
    ```python
    from matplotlib2tikz import save as tikz_save
    ```
   _Optional:_
   The scripts accepts several options, for example `height`, `width`,
   `encoding`, and some others. Invoke by
    ```python
    tikz_save('mytikz.tex', figureheight='4cm', figurewidth='6cm')
    ```
   Note that height and width must be set large enough; setting it too low may
   result in a LaTeX compilation failure along the lines of `Dimension Too Large` or `Arithmetic Overflow`;
   see information about these errors in [the PGFPlots manual](http://pgfplots.sourceforge.net/pgfplots.pdf).
   To specify the dimension of the plot from within the LaTeX document, try
    ```python
    tikz_save(
        'mytikz.tex',
        figureheight='\\figureheight',
        figurewidth='\\figurewidth'
        )
    ```
    and in the LaTeX source
    ```latex
    \newlength\figureheight
    \newlength\figurewidth
    \setlength\figureheight{4cm}
    \setlength\figurewidth{6cm}
    \input{mytikz.tex}
    ```

3. Add the contents of `mytikz.tex` into your LaTeX source code; a convenient
   way of doing so is via `\input{/path/to/mytikz.tex}`. Also make sure that
   in the header of your document the packages for PGFPlots and proper Unicode
   support and are included:
    ```latex
    \usepackage[utf8]{inputenc}
    \usepackage{pgfplots}
    ```
   Additionally, with LuaLaTeX
    ```latex
    \usepackage{fontspec}
    ```
   is needed to typeset Unicode characters.
   Optionally, to use the latest PGFPlots features, insert
    ```latex
    \pgfplotsset{compat=newest}
    ```

### Contributing

If you experience bugs, would like to contribute, have nice examples of what
matplotlib2tikz can do, or if you are just looking for more information, then
please visit
[matplotlib2tikz's GitHub page](https://github.com/nschloe/matplotlib2tikz).


### Testing

matplotlib2tikz 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 matplotlib2tikz and compare the output with
a previously stored reference TeX file.

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

### Distribution

To create a new release

1. bump the `__version__` number,

2. publish to PyPi and GitHub:
    ```
    $ make publish
    ```
