Plotting Themes#
PyVista plotting parameters can be controlled on a plot by plot basis or through a global theme, making it possible to control mesh colors and styles through one global configuration.

- Global Configuration
pv.global_themeis one of two global configuration objects. The other,pv.global_config, holds the core non-plotting settings.
The default theme parameters in PyVista can be accessed and displayed with:
>>> import pyvista as pv
>>> pv.global_theme
Default plotting parameters can be accessed individually by their attribute names:
>>> pv.global_theme.color = 'lightblue'
Here’s an example plot of the Stanford Bunny using default plotting parameters:
>>> import pyvista as pv
>>> from pyvista import examples
>>> bunny = examples.download_bunny()
>>> bunny.plot(cpos='xy')
These parameters can then be modified globally with:
>>> pv.global_theme.color = 'red'
>>> pv.global_theme.background = 'white'
>>> pv.global_theme.axes.show = False
Now, the mesh will be plotted with the new global parameters:
>>> bunny.plot(cpos='xy')
This is identical to plotting the mesh with the following parameters:
>>> bunny.plot(
... cpos='xy', color='red', background='white', show_axes=False
... )
Creating a Custom Theme#
You can customize a theme based on one of the built-in themes and then apply it globally with:
# Create a theme based off the DocumentTheme
my_theme = pv.plotting.themes.DocumentTheme()
my_theme.cmap = 'jet'
my_theme.show_edges = True
# Apply it globally
pv.global_theme.load_theme(my_theme)
Alternatively, you can save the theme to disk to be used later with:
my_theme.save('my_theme.json')
And then subsequently loaded in a new session of pyvista with:
pv.global_theme.load_theme('my_theme.json')
Default Interactor Styles#
Themes can also control the default interactor style used by new
plotters. Built-in styles use the same names as the corresponding
enable_*_style methods.
import pyvista as pv
pv.global_theme.interactor_style = 'terrain_style'
Custom interactor styles can be registered by downstream packages and used the same way once they are installed or registered at runtime.
