mpl_toolkits.axisartist.axis_artist.LabelBase¶
-
class
mpl_toolkits.axisartist.axis_artist.
LabelBase
(*args, **kwargs)[source]¶ Bases:
matplotlib.text.Text
A base class for AxisLabel and TickLabels. The position and angle of the text are calculated by to offset_ref_angle, text_ref_angle, and offset_radius attributes.
-
get_window_extent
(renderer)[source]¶ Return the
Bbox
bounding the text, in display units.In addition to being used internally, this is useful for specifying clickable regions in a png file on a web page.
Parameters: renderer : Renderer, optional
A renderer is needed to compute the bounding box. If the artist has already been drawn, the renderer is cached; thus, it is only necessary to pass this argument when calling
get_window_extent
before the firstdraw
. In practice, it is usually easier to trigger a draw first (e.g. by saving the figure).dpi : float, optional
The dpi value for computing the bbox, defaults to
self.figure.dpi
(not the renderer dpi); should be set e.g. if to match regions with a figure saved with a custom dpi value.
