Hi,

I have a series of datapoints on a xy scatter chart. The data points extend from x=-100 to x = 100. I am trying to shade two different regions - one -100<x<0 and the other 0<x<100. I went through the many examples on the net and figured out that a scatter chart with a 'timeline' category x axis or a bar chart with a timeline category x axis works well. However, when I change the primary x axis from -0.3 to 0.3 or so, the secondary axis range still remains the same and the shading gets messed up. I have to apparently change the secondary x scales too. I tried scaling the 2 x axes by the same numbers but I am not able to set negative values as limits. Can someone help me with this. I hope I made myself clear. I have been struggling with this for a day.

Thanks a lot.
