Hello, I'm trying to clear XY graph data each iteration of the loop, but "reinit to default" invoke node doesn't function. Are there any other options to clear data?

With the 2nd option (Express XY), you could also check if i=0 and use the output of that to decide whether to reset, rather than using the shift register.

Clear XY Graph Data Between Iterations

Eventually I created a case structure when i=0 then reset, and it works :-).

Thank you all for your replies.

You shouldn't need the case structure if you just wire the result of the i=0 comparison directly into Reset, rather than into the case structure selector.
