Hi Christopher,

I replied a few hours ago, but my message seems to have disappeared. Your demo works perfectly at 100% and 175% when compiled here by 10.4 with patched 1 - 3. So it looks as though there is a problem with my environment or code. Thanks for your help in progressing this issue. I'll get back to you if I find a solution.

I'm sorry your message disappeared, not at all sure what happened there. Glad to hear I may have been of some help, on the other hand - if you were to report back with any further news on this problem that would be greatly appreciated.

Found the problem. The Chart>Axis>Left/Bottom>Labels>Size settings were 33 and 27 respectively. These were fine for 100% scaling but not for 175%; setting them both to 0 fixed the problem. I wouldn't have found this problem if I hadn't been able to compare all my properties and settings with the one's in Ed's demo! I think you still need to fix your Navigator buttons for high-DPI though.

Thanks for your help with this.

Andrew

However... Just noticed that, although there is now no overlapping between axis titles and labels, the axis titles now aren't scaled up at 175%! How do I fix that?

Actually, measured them at 100 and 175% with a ruler and they are scaled up. So please ignore my comment.

Thanks, Andrew
