Channel not plotting on chart

Solved!
Go to solution

I've got a task that reads data from 5 different channels, which are all showing up fine on the task tab. But, when I try to plot them on a chart in a VI, I only see 4 channels - the first channel isn't showing up.

Is there a way to see all 5 channels on the chart at once? I've attached screenshots to show what I've got so far

Thanks in advance!

Hello mgodfrey,

 

I think I know where is the issue comes from.

I've tried the same and get the exact same result.

I paid attention to the plot legend, and find that the first plot's checkmark was not checked.

I have added or make it visible first plot (Input0) and it shows up. See screenshot below:

I have no idea why this happens but placing a checkmark on it solves the issue.
