FET Graphing

Hello, attached I have my LAbView program that I am currently working on. I am working on a Tech Project, helping a professor get a little further through out the program. we are using LabView17. When the program is ran the XY Graph of VG displays a single graph of the FET; which is good, but we are trying to get each "cycle" or "graph" of the FET to be displayed. So instead of having a single graphed line on the grpah, we would like to have multiple graphed lines. Thanks for any advice and or assistance.

For charts and graphs, context help shows all the different ways you can format the data to get different plotting results. I find this to be a really useful feature, because I always have to go check to see how such and such display requires its data to get a certain result.

For XY Graphs, each plot is a cluster containing two arrays of data. The first array is the X data and the second array is the Y data. For multiple plots on the XY graph, just make an array out of single plots. Here is a simple example of a multiplot XY Graph with dummy data. There is also a shipping example (Help >> Find Examples)

Sorry, but this program needs some serious TLC*. Do you know who wrote it?

 

You have at least four charts and graphs and nothing is labeled FET display. Can you be more specific?

 

*Some glaring issues:

  • Overlapping objects on the front panel and easter egg color theme
  • Mostly local variables and disconnected terminals.
  • "One iteration" FOR loops everywhere!
  • Deeply stacked sequences inside deeply stacked sequences! No!!!!!
  • Inner event loop with events lock the panel! Mouse down instead of value change events. Serious architectural problem.
  • Silly things such as writing terminals from their own local variable. That makes absolutely no sense. Unclear of the concept!

My professor and I are working on it together, I understand it is definitely messy. Just understand that he had been working on it for a few months before I got a hold of it, so a good chunk of the stuff is trouble shooting stuff that he added. I am simply just trying this to plot the multiple FET graphs in one graph instead of the single FET graph we are getting currently. My apologies, the cart where we have 4 DMMS and 2 separate power sources, plus an NI Elvis with the FET on it cannot be provided, so it is a lot of looking an guessing I would assume to someone just viewing the program.

There is no graph labeled FET display. Please be very specific so we don't look in the wrong place..
