Problem:

MAC: Numbers: I managed to obtain a scatterplot with 2 y-axes and a common x-axis. The data are represented OK; the set using the left y-axis is represented by points, but the set using the right y-axis is represented by columns. How do I replace te columns by points (with a colour different from the first set of course)? I could not find how!

I run Numbers version 6.2.1

Thank you in advance, Dirk
