HgTX,
Three things that may be of help:
1. Once you have a secondary Y-axis set up, you can select Chart/Options from the menu, and go to the Axes tab. Magically, you are now allowed to tick also the Secondary Value (X) axis!
2. If you - at some point - want two overlapping charts, the way to do it is to place the "background" chart into a chart sheet (Chart/Location - Place chart as new sheeet)
and then place the second chart "as object in Chart1"
3. If you have a mix of a chart and a scanned image (for example), you can select the chart area, and then format the fill pattern with the Fill Effects button to show a picture, which can be any image file.
Good luck experimenting.
Cheers,
Joerd
