Set the coordinate system to use for Annotation.xyann. Necessary to pass this argument when calling get_window_extentīefore the first draw.

Return the Bbox bounding the text and arrow, in display units. get_window_extent ( self, renderer=None ) ¶ Return the coordinate system to use for Annotation.xyann. Returns:ĭraw the Annotation object to the given renderer. In the case of text, a hit is true anywhere in theĪxis-aligned bounding-box containing the text. Test whether the mouse event occurred in the patch. If None, the annotation will only be drawn when xy isĭeprecated since version 3.0: arrow was deprecated in Matplotlib 3.0 and will be removed in 3.2.If False, the annotation will always be drawn.If True, the annotation will only be drawn when xy is.Whether to draw the annotation when the annotation point xy is Head_length=0.5,head_width=0.5,tail_width=0.2ĭefaults to None, i.e. If arrowprops contains the key 'arrowstyle' theĪbove keys are forbidden.
