When creating a plot from two data sets on two y axis with plotyy the interactive zoom tool misbehaves in multiple ways:
- The zoom does only work on datasets for the left y axis.
- Data sets for the right axis are not zoomed
- This leads to two different but overlapping x-axis. Obviously the x-axis is created twice.

1. I recommend removing the second instance of x-axis. I guess this should be done in plotyy implementation.

2. The qt interactive zoom tool has to be made aware of the second y axis and the data sets belonging to it.

Example code to create a plotyy:

Test with other graphics toolkits may be needed.
