# autolens.plot.PatchOverlay¶

class autolens.plot.PatchOverlay(**kwargs)

Adds patches to a plotted figure using matplotlib patches objects.

The coordinate system of each Patch uses that of the figure, which is typically set up using the plotted data structure. This makes it straight forward to add patches in specific locations.

This object wraps methods described in below:

__init__(**kwargs)

An abstract base class for wrapping matplotlib plotting methods.

Classes are used to wrap matplotlib so that the data structures in the autoarray.structures package can be plotted in standardized withs. This exploits how these structures have specific formats, units, properties etc. This allows us to make a simple API for plotting structures, for example to plot an Array2D structure:

import autoarray as aa import autoarray.plot as aplt

arr = aa.Array2D.manual_native(array=[[1.0, 1.0], [2.0, 2.0]], pixel_scales=2.0) aplt.Array2D(array=arr)

The wrapped Mat objects make it simple to customize how matplotlib visualizes this data structure, for example we can customize the figure size and colormap using the Figure and Cmap objects.

figure = aplt.Figure(figsize=(7,7), aspect=”square”) cmap = aplt.Cmap(cmap=”jet”, vmin=1.0, vmax=2.0)

plotter = aplt.MatPlot2D(figure=figure, cmap=cmap)

aplt.Array2D(array=arr, plotter=plotter)

The Plotter object is detailed in the autoarray.plot.plotter package.

The matplotlib wrapper objects in ths module also use configuration files to choose their default settings. For example, in autoarray.config.visualize.mat_base.Figure.ini you will note the section:

[figure] figsize=(7, 7)

[subplot] figsize=auto

This specifies that when a data structure (like the Array2D above) is plotted, the figsize will always be (7,7) when a single figure is plotted and it will be chosen automatically if a subplot is plotted. This allows one to customize the matplotlib settings of every plot in a project.
