Install

This package requires \(\LaTeX\) to be installed. Ensure that the latex executable is available on your system’s PATH.

pip install texplot

conda install s-ameli::texplot

Set Theme

texplot can set theme either globally or locally:

Set Theme Globally

Call texplot.set_theme function to set the texplot theme globally in your script:

>>> import matplotlib.pyplot as plt
>>> import texplot
>>> texplot.set_theme()

>>> # Plot an example function
>>> fig, ax = plt.subplots()
>>> texplot.examples.plot_function(ax)
>>> plt.show()

The theme set as described above will affect your entire Python script for its duration. However, you can revert to the default matplotlib theme at any time by calling the texplot.reset_theme function as shown below:

>>> # Resetting to default matplotlib theme
>>> texplot.reset_theme()

>>> # Plot another example function
>>> fig2, ax2 = plt.subplots()
>>> texplot.examples.plot_function(ax2)
>>> plt.show()

>>> import matplotlib.pyplot as plt
>>> import texplot

>>> with texplot.theme():
>>>     fig, ax = plt.subplots()
>>>     texplot.examples.plot_function(ax)
>>>     plt.show()

>>> import matplotlib.pyplot as plt
>>> import texplot

>>> @texplot.theme()
>>> def plot():
>>>     fig, ax = plt.subplots()
>>>     texplot.examples.plot_function(ax)
>>>     plt.show()

>>> plot()

Theme Options

You can customize the theme by passing arguments to either the texplot.set_theme or texplot.theme functions. The parameters for both functions are identical and detailed in the API reference. The available arguments are as follows:

In the example below, we configure a dark background style, increase the font size by a factor of 1.2, and set the font family to sans-serif:

>>> import matplotlib.pyplot as plt
>>> import texplot

>>> with texplot.theme(
...         rc={'font.family': 'sans-serif'},
...         style='dark_background',
...         font_scale=1.2):
>>>
>>>     # Plot an example diagram
>>>     fig, ax = plt.subplots()
>>>     texplot.examples.plot_bifurcation_diagram(ax)
>>>     plt.show()

Show and Save Plots

When working on a machine without display graphics, such as a remote server that lacks X11, displaying plots is not possible. Instead, plots should be saved. The texplot.save_plot function provides a simple wrapper around matplotlib.pyplot.savefig to facilitate this. Additionally, the texplot.show_or_save_plot function attempts to display plots initially. If no graphical backend is available, it saves the plot instead. Additionally, you can configure it to both show and save the plot. Here is an example:

>>> import matplotlib.pyplot as plt
>>> import texplot

>>> with texplot.theme(rc={'font.family': 'sans-serif'}):
>>>
>>>     # Plot an example function
>>>     fig, ax = plt.subplots()
>>>     texplot.examples.lorenz(ax)
>>>
>>>     # Show and save plot
>>>     texplot.show_or_save_plot(plt, default_filename='lorenz.pdf',
...                               transparent_background=True, dpi=200,
...                               show_and_save=True, verbose=True)
plot saved to '/home/user/lorenz.pdf'.
