Hi; I suggest to you to take some basic labview courses that could be useful to solve questions like these.
For the probelem you submitted, you should keep in mind that, to graph the charge/discharge values, tou must use the time as a variable inside your formula.
Time begins from zero and goes on.
So when the loop is running, you should calculate the iteration's delay and put it (in seconds) inside your formula, to extract the output Vc value at that time.
Remebmer to put ALWAYS a fixed delay (0.005 s in the case) inside your while loops to leave time to the CPU.
You could use the Waveform Charts to refresh your output graph at each iteration.
In this example the x axis is the nr of point. Each nr of point means a delay of 0.005 s sampling time.
The Output Waveform chart nr 2 uses a formula node, that is more practical to calculate the output and gives the same results.
The waveform graph (the output outside the loop), gives you the exact timing correlation and it is available after the STOP.
You will be able evaluate the first ms instants by using the graph zoom tools.
Now you could be able to do by yourself the discharging vi, that could be a useful exercise.
Kudos are well-accepted!
Bye,
Marco
