NNSOM.plots.SOMPlots.gray_hist

SOMPlots.gray_hist(x, perc, mouse_click=False, **kwargs)[source]

Generates a grayscale histogram for the SOM, where the shade of each hexagon represents the corresponding value from the provided percentage array.

Parameters:

  • x (array-like) – The input data to be visualized in the histogram.

  • perc (array-like) – An array containing the percentage values to be represented by the grayscale shades, where higher values correspond to darker shades.

  • mouse_click (bool, optional) – If True, enables the plot to respond to mouse clicks, allowing for interactive functionality such as querying or modifying neuron data, by default False.

  • **kwargs (dict) – Arbitrary keyword arguments that can be passed to the event handler onpick when an interactive element is clicked. Common parameters could include data specific to the plot or visualization settings.

Returns:

  • fig (matplotlib.figure.Figure) – The Figure object containing the plot.

  • ax (matplotlib.axes.Axes) – The Axes object containing the plot elements.

  • patches (list) – A list of matplotlib.patches.Patch objects representing the inner hexagons colored based on the grayscale values.

  • text (list, optional) – A list of matplotlib.text.Text objects displaying the hit counts, included if textFlag is True in the underlying hit_hist method.
