How to get two different vertical axis in one graph?

Dear reader,

We are trying to make a graph with different vertical axis (one is a scale division for a Landau fit on measurement results and the other one is a scale division for the number of hits on the detector). They both use the same horizontal axis (time). We have been leafing through the manual but so far have not been able find anything helpful.

Does anybody have some experience with this or an idea where we have to look for more info on this subject?

Thanks in advance.
