Chart displaying "Trendline Error"
blaughlin1992 I deleted that series causing the error and added it back. Error gone. A mystery.
I am surprised to read that the problem is still occurring. A while back the problem went away for me (Excel 365) and all of the workbooks that exhibited the problem started to work properly. I did report it by posting a "Comment" to Microsoft and the problem went away a few weeks later. I thought that they had fixed it.
Hello there,
a week ago I downloaded a new language tool for Portuguese, when I did it, Microsoft made minor update to my 365 office, I saw that Outlook installed a better search tool....etc... etc, after this, I started having the issue with Excel, that label indicating trendingline error is in one of my workbooks in all its sheets, I have tested everything but the label remains there, there isn't a clear way to get rid of that label.
