matplotlib.axes.Axes.secondary_yaxis¶
-
Axes.
secondary_yaxis
(self, location, *, functions=None, **kwargs)[source]¶ Add a second y-axis to this axes.
For example if we want to have a second scale for the data plotted on the yaxis.
Parameters: - location{'top', 'bottom', 'left', 'right'} or float
The position to put the secondary axis. Strings can be 'top' or 'bottom' for orientation='x' and 'right' or 'left' for orientation='y'. A float indicates the relative position on the parent axes to put the new axes, 0.0 being the bottom (or left) and 1.0 being the top (or right).
- functions2-tuple of func, or Transform with an inverse
If a 2-tuple of functions, the user specifies the transform function and its inverse. i.e.
functions=(lambda x: 2 / x, lambda x: 2 / x)
would be an reciprocal transform with a factor of 2.The user can also directly supply a subclass of
transforms.Transform
so long as it has an inverse.See Secondary Axis for examples of making these conversions.
Returns: - axaxes._secondary_axes.SecondaryAxis
Other Parameters: - **kwargs
Axes
properties. Other miscellaneous axes parameters.
Warning
This method is experimental as of 3.1, and the API may change.
Examples
Add a secondary axes that converts from radians to degrees
