The VI for today is "Ramp Pattern.vi". We have probably all written our own version at some point, or just do the math in the for loop. If you look under the hood you'll see why this one brings me back to the good-old-days of LV2 and LV3. Back then, creating an integer array in a For Loop with N>100 caused a significant delay so I had to write a C version and use a CIN. Things are much better today, hardware and software wise, but I guess a few of the old techniques are around.
Here is my example (screenshot only for now)
Pretty clear what I am graphing, still looks pretty cool.
If you are new to VIOTD, see here for the basic idea.
