autogalaxy.plot.subplot_basis_image#

subplot_basis_image(basis, grid, output_path=None, output_format=None, colormap='default', use_log10=False, positions=None, lines=None)#

Create a subplot showing the image of every light profile in a basis.

Produces one panel per profile in light_profile_list, arranged in rows of up to four columns. Each panel title is taken from the profile’s coefficient_tag attribute.

Linear light profiles cannot be plotted directly (their intensity is solved via inversion), so an error is raised if any are present.

Parameters:

  • basis (Basis) – The basis (e.g. MGE or shapelet set) whose component images are to be plotted.

  • grid (aa.type.Grid1D2DLike) – The grid on which each light profile image is evaluated.

  • output_path (str or None) – Directory in which to save the figure. None → plt.show().

  • output_format (str) – File format, e.g. "png".

  • colormap (str) – Matplotlib colormap name, or "default".

  • use_log10 (bool) – Apply a log₁₀ stretch to the image values.

  • positions (array-like or None) – Point positions to scatter-plot over each panel.

  • lines (list or None) – Line coordinates to overlay on each panel.
