However, if the norm only The bounding boxes are returned in display coordinates, so we transform them to axes coordinates using the inverted axes … Typically this is automatically registered as an event handler axes. or other unusual circumstances. to using a default locator. Function signatures for the pyplot interface; all but the first are also method signatures for the colorbar () method: colorbar(**kwargs) colorbar(mappable, **kwargs) colorbar(mappable, cax=cax, **kwargs) colorbar(mappable, ax=ax, **kwargs) Using different colors in a Matplotlib bar plot is a powerful technique for adding emphasis to a visualization.
