Hi,
I have the following data:

column A:
jan
feb
mar
apr

column B:

5
9

column C:

I would like to get a chart where in the horizontal axis I have the
monthes and I have 4 points, connected by lines.
The first point will have the value 3 in correspondence of the left
vertical axis and the value 26 in correspondences of the right vertical
axis.
....
The fourth point will have the value 9 in correspondence of the left
vertical axis and the value 38 in correspondences of the right vertical
axis.


How can I can do it?

Thanks
