Incorrect data appearing on waveform chart

[jdamato3]

I have two waveforms charts in my vi, both plot current vs. voltage. After I build an array of data points, I send them to waveform charts. The datapoints are completely incorrect when plotting (Scale, no points, not autoscaling) although, when I export my data to excel it is perfect. Any possible solutions on how to fix this? I've attached my vi for reference (sorry if it's a bit messy). I'm using tab control and my problem is falls under the case "Ids vs. Vgs".

If you want current on one axis and voltage on the other, you need to be using the XY Graph. A chart is not at all appropriate. Turn on Context Help.

Thanks, I got it to work, BUT I'm trying to get the graph to update inside of a while loop. The problem is the cluster the XY Graph accepts needs to be placed outside of the loop for indexing purposes. Any way around this?

You can cheat and use the Express XY Graph or use a couple of shift registers to build the separate X and Y arrays. There is also the shipping example called XY Chart.

You are the man, got it. Thanks for the help!
