matplotlib.axes.Axes.twiny#

Axes.twiny()[source]#

Create a twin Axes sharing the yaxis.

Create a new Axes with an invisible y-axis and an independent x-axis positioned opposite to the original one (i.e. at top). The y-axis autoscale setting will be inherited from the original Axes. To ensure that the tick marks of both x-axes align, see LinearLocator.

Returns:
Axes

The newly created Axes instance

Notes

For those who are 'picking' artists while using twiny, pick events are only called for the artists in the top-most Axes.
