The curve shown in the XY graph is inconsistent with the actual data

[ChinaOliver]

Has anyone ever been in this situation? When the data is displayed on the XY graph, the Y-axis scale is inconsistent with the actual data.
However, the data exported through the XY chart menu "export data to excel" is consistent with the actual data.
That's a very strange question. Can someone tell us the root cause? Thank you very much.

I think you have multiple Y scales, so the plot that don't seems to be correct is probably using the 2nd scale that you are not showing.
FYI, if you zoom in the Excel export will only show that data, and it's very strange that it using 1k and 10k instead of 1000 or 10000

This is why "Export to Excel" is a useless feature. The data is exported using the display format of the plot's axes; since the plot uses SI formatting, it is expressed as 10k, 100k, etc. This does not help if someone wants to plot the data in Excel.

I checked the Y scale, and you were right. But this problem is really troubling, because the same display window shows that other curves are normal, only the attached curve is abnormal. Try to set each curve to correspond to the Y scale, this problem can be solved. Have a nice day.😀
