Set were Y-axis crosses X-axis
But, isn't the purpose of having two axis to be able to show data series of different magnitudes in the same graphing area? If you really want to have -zero- at the same height on both axis you should have the relationship of both axis (minimun - zero - maximum) and the number of gaps between grid lines exactly the same. In your case, the primary axis goes from -600 to 300 in 9 steps. Your secondary axis goes from -200 to 1000 in 6 steps. I guess that when you set the maximum on your primary axis to 3000, and the gap width (=majorn unit) to 600, that your horizontal axis will be at the same level on both verticals. But then you might not like what you get either. Having both series on the same axis would be preferable, I believe.
I'm using the same typ of diagram for several different cases and all other diagram starts with zero (no negative values), so this is the only one with this issue. And normally the magnitudes differs more the ten times. I also like have the same structure for all diagrams. But as you pointed out the magnitud for all series can, in this case, be presented in the same scale. So in order to keep the same structure I have now set the primary and secondary scale to the same max/min that envelope all series. This looks way better!
Really a obvious solution but I couldn't see the forest for all the trees.
Thanks.
