Clear subpanel XY graph?

[Gonso]

Hi all, 

Does anybody know  how to clear a XY graph in a subpanel? I have a sub VI that acquires some data and shows it in a XY graph (and clears graph after each iteration). The main VI calls that subVI but it seems to remember all previous data stored in the XY graph and do not clear it. I've tryed to reload the subvi but doesn't work.

Thanks

If you set the subvi's Properties > Execution > "Clear indicators when called " property to true, does that clear the XY graph when first launched? Make sure the graphs default data is a clear graph too (manually clear the graph data, then set as default data, save subVI).

Thanks, but it does not work that way as well.

You might have to clear it programmatically then. Send an empty array to the Property Node > Value property.
