hi friends,

I have some plots in my chart plot legend box, and they are not useful, so how can I delete them? please see attached for the screenshot, thanks.

for example, how can I delete plot34---plot41?

The number of plots displayed depends on the dataset wired to terminal, so as a first step, change the data. Unfortunately you have not attached your VI and from the picture we cannot tell what's going on.

You did not attach the VI.
