Use an enumeration to select local variable to plot

[Hummer1]

I have some arrays of 2D point locations stored in local variables.  For diagnostic purposes, I would like to be able to select one (any) of these current local variables and plot them.  I can do this one at a time by indexing the array, and adding a 255 to the z value of each array coordinate pair and then passing them all indexed to an intensity graph.  Setting a time delay lets me "look" at the relative positions of array points as they are plotted.  I know none of you have had problems with row,col x,y reversals and the like, but I need something to help me visualize these interactions.  Stepping through the simultaneous plot of two of these arrays would let me see which points relate to others as I work on the arrays.  Rather than having to "program" each time I wanted to have the point locations display, I would rather choose them from a list from some little sub vi that I could run any time I wanted...How might one go about that?  Or, is there a better way.

Basically, how do you populate an enumeration control with the list of local variables?

Thanks.

I believe there's a property node for an enumeration control that you can use to set the entries in it.  You might want to post to the LabVIEW forum - they'll probably be able to help you more!

You can't change the labels for an enum during runtime.  However, you can use a pull down list (right next to enum) that will do exactly what you want.  Just use the property "Labels" to set all the items for the control.
