Waveform chart

[newman3108]

Hi, im having some trouble setting up a waveform chart with multiple plots. The plot gives the excel output in the picture, but i dont need to plot the channel name (102,103,104), just the values. I'd like a separate plot on the same graph for each channel. Probably something to do with the arrangement of the array but cant seem to fix it.

Thanks

You are adding the channel names for each iteration of the loop. Just don't add them or add them only the first time.

How do i only add them the first time

From your code, the simplest (no, there is always a simpler way) would be to have a case-structure around the build-array node in the loop and only do that on i=0 and on all other iterations only add the data.

Reduce your FOR loop to something like this:

...And then if you want the channel numbers on the top row you can use build array after the loop. You probably don't want that in the chart data anyway, but only when you export the data (to Excel).

Thanks for your reply,

Adding the waveform chart before building the array results in only 1 channel being plotted and showing up in excel.

Can anyone help with this? 

How do I separate the points into different plots 

Thanks

Insert a Build Array before the chart.  Make sure it is only 1 input tall.
