Altenbach, XY-graphic

[asa]

Hello altenbach, here is the program. I am taking continuous data from two sensors.The question were about how to clear the graphic after I stop the data collection,so when I start to collect the new data the old data does not appear,and how to detect and display in an indicator the first element of the data.Thanks, I really appreciate your help.Is there any way to contact you directly??
Regards,
Asahel

You just need to right-click on the "initializer Terminal" and select "create constant". Wire this constant also to the other terminal as shown in the attached image. (Sorry, I don't have any DAQ hardware, so I cannot test run your VI). You need to understand the operation of feedback nodes (shift registers). Unless they are initialized at the left border, they retain their data between calls or runs. A very useful feature for certain scenarios, but you need to ensure that the contents do not grow without limits.
