I have a problem while creating a dual Y-axis chart.
Let's say if I have 2 sequences, the A sequence has 100 and 84, and the B sequence has 100 and 36. When I create a single Y axis line chart, it seems no problem. But if i use the left Y-axis for A sequence and the right Y-axis for B sequence, the
chart can't display correctly. Two lines will be overlap, which is obviously wrong.
I know that I can manually adjust the scales of axes but I think it is caused by the default algorithm which will auto set the scales of the axes in Excel. Normally, we will not check and adjust the scales as we trust Excel.
Can anyone help me on this issue? Is there any excel add-in could auto adjustment the algorithm for dual axes chart? Thanks.
