How do you create a column plot that is just like a normal column plot with two y-columns (grouped colums), but both column series have y-axis of their own? The problem is in adjusting the column offsets and spacing when two layers are used.

Hi emk:
This requires a bit of fiddling but it can be done.
- Insert an empty column between the two Y columns of your worksheet. Now you have three Y columns.
- Select the first two columns (the second Y column will be empty, of course) and make your column graph
.
- Add a linked "Right Y" axis to your column graph (Edit:New Layer(Axes):Linked:(Right Y). The column graph now has two layers. You may need to adjust the right Y axis' From and To values.
- Click once on the graph's layer 2 icon to make sure that layer 2 is active, then select the second and third Y column (again, the second column is empty) and drag your selection to the graph.
- Open the graph's Plot Details dialog box. Select the layer 2 data sets and on the Group tab, set Edit Mode to Independent. Once done, you can change the appearance of the third Y column plot to suit you.
So what you are doing is creating and twice plotting an empty data set, which then acts as a "placeholder." Let me know if I haven't been clear enough. Good luck to you.

Thanks Mike! This is just what I was looking for. I tried something similar with dummy data not plotted but used to direct the formatting. Now I realize that the problem I had was due to my x-axis not being categorical (for some reason Origin seems to rescale the x-axis for the second layer and if the x-axis is not categorical, the columns are misplaced). I created a template to plot similar data, now I only need to create the dummy column in btw the real data and plot/template does the rest.
(One might ask why to plot columns with two y-axes as you normally use this plot to facilitate column height comparisons, but we want to show that the paired colums behave similarly relative to the category)
