The problem of disordering lines in waterfall graph

When I zoom in on the image, the problem seems to disappear. See the image below. I do not know why.

Does the issue toggle when you change the size of the graph or the distance between traces? Would it be possible to post an example experiment file? Which version of Igor and OS are you using? You could also create an alternative 'fake' waterfall by just plotting all traces yourself and then offsetting them via trace offset.

Hi, chozo,

Thanks for dealing with my question.

The issue persists when the size of the graph changes. I currently do not know how to change the distance between traces. But when I zoom in on the problematic area, as I said, it turns to fine. My version is IGOR PRO 9.04, 64-BIT. My computer is Windows system. 

I built a matrix using the concatenate command in another file, but the result was fine. Interesting. See the figure. in this case, there are 71 traces, less than the former figure.

Thank you.

Dear Chozo,

The problem has been solved. It was related to my data. the backgrounds of the data in the two traces were doubled compared with other traces. Thank you.

Ok great!
