Overlay runtime data on top of excel data

[Matt-UHart]

Hi all,

I have data from Excel that I would like to plot on a graph in LabView, then as the program is collecting data, I would like to overlay the current data on top of the Excel data as a visual to make sure that the test is running well.

Does anyone know where an example of such a vi might be?  Or maybe you can give me some hints on how to do this?

Thanks for any help,

Matt

Hello,

Basically, you would first load your data into LabVIEW and have that be your initial array. You would then build an array within a loop that reads your runtime data. The attached example shows the general concept.

Zach,

thanks so much for getting back to me.  How would you manipulate this code so that if I were to hit a stop button that it would stop execution of the for loop?

Thanks again,

Matt

Hello,

If I did not have a maximum number of iterations, I would use a while loop instead. Otherwise, if there is a maximum number of iterations, a stop terminal can be added to a for loop by right clicking the loop border and the selecting the option for a conditional terminal.
