combo box choose several

[TobiasMeier]

Hello

I try to make a combo box, where it should be possible to choose several values at the same time. The item list contains a bunch of historical traces and I want to do a graph showing only the chosen ones. Is ther any possibility to set a bool for each item, which is per default false and can be changed to true, so this plot is shown in the graph?

thanks

Hello,

Using property node of the graph you can. Property 'active trace' and 'trace vible', active trace to choose wich one and visible set to true or false to be visible or invisible (hidden ?). But in beginning you should transfer all traces to the graph.

Hope it will help you

A listbox might work better to select the traces you want.

See the attached vi.

thanks for your help

sadly this does not work

@gregory 45: I can not find "active trace" in the property node from the graph, either not in the one of the combo box.

@vt92: sadlz I can not use zour added vi, because I run LabView 8.6 and your vi is built with a newer version.

Hi,

Here come an example for trace visible or not on graph.

thanks again.

but this is not what I want. I have a long list of signals. It should be possible to choose several channels and show them in a graph. I already can create either a combo box or a listbox with the names of the channels. What now is my problem, is to show only the chosen channels.
