If I have a chart on a form, anchoring all sides to the form will make the chart expand as I expand the form. That is simple.

If I have 2 charts or even better 3 charts stacked vertically on a form. How do I set the anchors so that when I expand the form, all charts expand proportionnally.

For the x axis this is simple, anchor both sides of the charts to the form sides.

But for the height ( Y axis) I have been playing with all kinds fo combinations for the last hours and cannot find one that does what I want.

Is this possible?

Thanks
