I have a ScatterChart that I am setting
.Tooltips.Display = TooltipDisplay.MouseMove .Tooltips.Format = TooltipStyle.LabelPlusDataValue
Sometimes when I hover over the points on the chart I see the tooltip. Other times, nothing shows up unless I switch to another application without closing my application, and then back to mine. The tooltips show up then. I'm assuming that chart getting invalidated and then drawn again is fixing this, but I don't know why it happens.
Any suggestions would be greatly appreciated.
i haven't heard any reports of the problem you described. it sounds like it could be a bug in the chart DLL, though. are you able to reproduce it in a sample application?
Anyone have any suggestions?
