Yes:
xdata, ydata = ax.transData.invert

Hi,
I want to implement a cursor on a diagram using native Qt routines. For
this, I would need to transform data (axis) coordinates to display
coordinates.
The manual of matplotlib, API "axes" just jays that there are some
public attributes 'transData' and 'transAxis', but without an
explanation.
