tab control with a case structure

[jpm0887]

I am having trouble getting my tab control to work with case structure. I have 4 tabs that i want displayed on my front panel, each with a separate graph. When I click on any tab besides the first one there is nothing shown on the graph. I think i have some wiring issues. Any ideas?

Merging the tab control with the signals and then wiring that to a case statement makes absolutely no sense. Trying to wire the case selector boolean to a graph makes even less sense.

Do not merge the tab control with anything. Do not place case statements inside your outer case statement. Just place the graph inside the outer case statement and wire the signal to it.

I don't think you need the inner case structures or the merge signal functions.  The way you have it wired, you will have to click on the correct tab BEFORE you run the program.  This is because you are only populating one graph due to your case structure being wired to the tab selector.

Alternately, you could eliminate the outer case structure and populate all the graphs, then just click on the tab of your choice to see each graph.

Interesting VI. But, what do want to do?

The whole ting seems to be infected by a bad case of the "express VI abuse" syndrome.

how would i go about doing that?

Make your block diagram look like this:

See also this and this discusion. Most of the time, tab controls don't need any code. 😄

(You also have a couple of breakpoints (one on the entire diagram and one on the while loop). Make sure you remove them. Look for the red outlines.
