deleting data from xy graphic

[asa]

Hello.I am plotting a continuous XY graphic(into a while loop). After I finish the collection of data and I stop the program ,I clear the XY graphic but when I run the program again for a new measurement the old information appears in the XY graphic with the new one.How can I delete the previous data to sart a new data collection.Thanks in advance, Asahel

Just a wild guess, but are you using a shift register to hold your graph data?

Make sure you initialize it at the left edge. (Simply click on the left shift register and select "create constant".

If this is not it, please post the code.
