Hello there,
I am using a 3Y graph. However, when I plot the data, some extra lines are shown on the graph. I don't know where they are coming from. They are not part of the data. When I enable the speed mode, these line disappear and graph appears as it is. But, as soon as I disable the speed mode, these lines again appear. Please check the screenshot below. Please let me know if anyone knows the reason and solution to this. Please note that I have a very large data set.

Hi,
it looks it is because the X data of the red curve are not monotonic ascending or descending.
In Speed mode, some data will be skipped and if the wrong data is skipped it will look fine.
However, could you try sort the XY data of the red curve first and see whether it helps. Highlight the whole two columns of XY data of the red curve, right click and choose "Sort Columns: Ascending"
