HI, I have made 3 vi, for keithley model 6430 (voltage current source meter), 6487 (voltage source), 3390(function generator). Now I need to plot a 3-d plot that uses current voltage sweep made from 6430, and voltage sweep made from 6430 and frequency sweep made fro 6430. I will make it more clear..it will be like for one frequency, their will be a sweep of voltage from 6487 and for each voltage from 6487 their should be voltage sweep from 6430. So basically it will be a nested loop structure. As I am a newbie to labview I dont know how would i take data from the innermost vi (6430) and send it to outermost vi and I dont know how to plot a 3d surface that also in real time. I am attaching .jpg to make it more clear I need to make a table like this and plot 3d curve that should can be saved as thay will keep changing as the loop will go on. Thanks a lot
