multiple graphs in XYgraph!

[Fonsi]

Hi guys!
I have a litle problem. I am using a program, to draw several curves in a only one xygraph, I have a while loop, i read from the file (spreadsheet file), each file take 2 curves (4 arrays). I want to open differents files into the graph, but when i draw one file, with i try to open other the graph is cleared and draw only the new file.
This option is for draw differents curves to compare them.
How can I do it for see several curves?.

Thanks, i would be grateful to you...! (if it possible with a example i could to see better)

Hi,

I have attached a vi which adds a new curve to xy graph without clearing the previous graph.

Change x & Y array values & press Add button to add the curve to xy graph.

Hope this works. If your problem is not solved, pl. write. Your feedbacks are welcome.
