plot_histogram_and_save()[source]#

Plot and save a histogram of the height map

Returns:

  • fig (plt.figure.Figure) – Matplotlib.pyplot figure object

  • ax (plt.axes._subplots.AxesSubplot) – Matplotlib.pyplot axes object

plot_and_save()[source]#

Plot and save the images with savefig or imsave depending on config file parameters.

Returns:

  • fig (plt.figure.Figure) – Matplotlib.pyplot figure object

  • ax (plt.axes._subplots.AxesSubplot) – Matplotlib.pyplot axes object

save_figure()[source]#

This function saves figures as plt.savefig objects.

Returns:

  • fig (plt.figure.Figure) – Matplotlib.pyplot figure object

  • ax (plt.axes._subplots.AxesSubplot) – Matplotlib.pyplot axes object

save_array_figure() → None[source]#

This function saves only the image array as an image using plt.imsave

topostats.plottingfuncs.add_bounding_boxes_to_plot(fig, ax, shape, region_properties: list, pixel_to_nm_scaling: float) → None[source]#

Add the bounding boxes to a plot.

Parameters:

  • fig (plt.figure.Figure) – Matplotlib.pyplot figure object

  • ax (plt.axes._subplots.AxesSubplot.) – Matplotlib.pyplot axes object

  • shape (tuple) – Tuple of the image-to-be-plot’s shape.

  • region_properties – Region properties to add bounding boxes from.

  • pixel_to_nm_scaling (float) – The scaling factor from px to nm.

Returns:

  • fig (plt.figure.Figure) – Matplotlib.pyplot figure object.

  • ax (plt.axes._subplots.AxesSubplot) – Matplotlib.pyplot axes object.
