Excel Graph and Print Preview Disagree

I'm having a strange issue with Excel Graphs. I have data added, and add a trendline, but print preview shows the trendline running in a different direction altogether. The one shown in the spreadsheet is correct, and the print preview is incorrect. Any suggestions?

 

Print it out and see who wins. Print preview is more about showing extent than specific content.

 

Unfortunately Print Preview wins, which is the incorrect graph information. I've tried duplicating the data into a new spreadsheet, by copying and pasting, and receive the same results. Any other suggestions?

 

A couple of things for you to try:

If this is a custom graph that you have created and subsequently added the trendline, try going back and reselecting Custom graph and user defined from the Type tab and see if redefining it makes it print correctly.

If that doesn't work, here is a link with several things some of which may be relevant. Even if not, it's a good resource to have in your Favorites.

Good luck.
