Hallo All !
i made a small program that can calculate the bandwidth of the magnitude in the fourier domain resulted from this mathematical formula: (V(t) = 1/(4*((pi)*a*t)**3/2) * exp(-(x**2+y**2 + z**2)/4*a*t) ) "Where x,y,z,a have particular values".
Now i would like to illustrate the relation between this bandwidth and the time in waveform Graph. i mean a waveform graph that shows me how the bandwidth changes when the time changes for example from 0 to 200. So the time should be the x-achse and the bandwidth should be the y-achse.
How can i do it? i attached my program.
thanks in advance

You could use an XY Graph, which is a 1D array of clusters that hold the X and Y values.
By the way, you may want to get rid of your local variable (FFT) and just wire it directly to the indicator.

Why dont you try something like this:
Just subsitute in your values for A,X,Y, and Z.
You can enter a start and end for the range, and number of points to evaluate.
If you need to change a,x,y, or z, you use some string functions to concatenate a function together.
If you need help doing that, let me know and I will show you and example.
