Hi every body,

First of all sorry for my bad English, it's not my main language.

So, I try to do a linear graph with a scroll bar for X axis and one other for Y axis.

That is OK, it works fine.

Now I want to add a secondary Y axis and that is the problem.
When I scroll on Y axis the secondary scale don't move but the data, based on the second axis, does so the data is no more "in front of" the scale.

I see 2 possibilities:
- create a second scroll bar for the secondary axis => this one move the axis but not the data and the primary scroll bar does the same than before. I probably do a mistake somewhere or something is missing.
- synchronise the secondary axis with the primary scroll bar => I didn't know how to do this.

For now, I don't really know if I will choose solution 1 or 2, so if it's possible tell me how to do both.

Thanks for all the reply.

EDIT: The 2 axis didn't have the same range, one is -1000 to 1000 the other is 0 to 100, I didn't know if it make a difference.
