Origin Ver. and Service Release (Select Help-->About Origin): 9.1.0 Sr3 Operating System: Windows 7
In plot details, I can't change the size of the sub windows (the list of workbooks and list of columns)
This means that if I want to select any workbook or any column I almost always have to scroll, when plotting over 20 item that gets very annoying. I want to be able to see much more of the list of workbooks and columns. In origin 8.6 I believe this was possible.
If you right click in each panel, you will see Enlarge/Shrink Panel at the bottom of context menu.
BTW, you can click the double up or down buttons on the right to hide or show top/bottom panels. And depending on which panel is showing, you can drag the top/bottom edge of the dialog window to expand/shrink.
