Thank you! I see the problem. In Multi-plot Main, under Trim Data Samples, the Tail value is set to 50. This causes multiplot to ignore the last 50 points. You'd need to normally set Tail to 0 process all of the data points. However, in the measurements table you sent, I noticed that the last 4 rows in the data are non-standard (labeled Mean, SD, Min, Max). You may want to remove those rows or set the Tail value to 4 (you'd still get 4 NaNs at the bottom).

By the way. there is a shortcut to access the "Add new data columns" functionality in Multi-plot Y-data. If it helps, you can simply click on the "New Col" icon on the left hand side of the row you are interested to work with.
