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.
