How to Increase the Figsize of Plot or Diagram?

[Jerry2001]

Hello everyone, I'm trying to increase the figure size of the chromaticity diagram but haven't found much luck. I tried to insert figure=plt.figure(figsize=(20, 20)) in plot_chromaticity_diagram_CIE1931. But, the resulting figure size has 0 axes and the saved file is just a transparent file. Thank you so much!

Hi @Jerry2001,

Great questions, there are a few ways to do it! All the Colour plotting definitions starts by creating a figure and an axes with the colour.plotting.artist definition which can either use an existing axes or create a new figure using plt.rcParams['figure.figsize'].

With that in mind:

Defaults

colour.plotting.plot_chromaticity_diagram_CIE1931()

Using an Existing Axes

figure = plt.figure(figsize=(19.2, 10.8))

colour.plotting.plot_chromaticity_diagram_CIE1931(axes=figure.gca())

Using a Temporary Override

with plt.style.context({'figure.figsize': (12.80, 7.20)}):
    colour.plotting.plot_chromaticity_diagram_CIE1931()

Using a Definition with the Colour Decorator

@colour.plotting.override_style(**{'figure.figsize': (8, 6)})
def plot_custom_chromaticity_diagram(**kwargs):
    return colour.plotting.plot_chromaticity_diagram_CIE1931(**kwargs)

plot_custom_chromaticity_diagram()

This Google Colab Notebook has the above code and defaults plots to show that the state is restored properly after each custom figure size.
