calour.experiment.Experiment.plot_hist¶

Experiment.plot_hist(ax=None, **kwargs)[source]¶

Plot histogram of all the values in data.

It flattens the 2-D array and plots histogram out of it. This gives a sense of value distribution. Useful to guess a reasonable clim for heatmap.

Parameters:	ax (matplotlib.axes.Axes or None (default), optional) – Axes object to draw the plot onto; otherwise uses the current Axes. kwargs (dict) – key word arguments passing to the matplotlib.pyplot.hist() plotting function.
Returns:	the count in each bin, the start coord of each bin, and hist figure
Return type:	tuple of 1-D int array, 1-D float array, matplotlib.axes.Axes
