thanks! i was hoping for reply!
i understand the electric field applet better now


but i actually want to record for different runs of the experiment like 15 to 20 different play and initialize.
like in datalogger, different "runs" can be captured as different data sets?
maybe need to store in txt files? i am just guessing.

it will have to involve clicking the initialize button, any way to still collect data?

i upload this applet to illustrate my intent more clearly in the applet i have been remixing ;D
