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.

Create a Text instance at x, y with string text.

Valid keyword arguments are:

draw(self, renderer)[source]

Draws the Text object to the given renderer.

get_window_extent(self, 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.

rendererRenderer, 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 first draw. In practice, it is usually easier to trigger a draw first (e.g. by saving the figure).

dpifloat, 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.
