User-Selectable Analog Inputs for X-Y Graph Axis?

[DtempleJGR]

Hey,
I've done a lot of looking at demos/examples, and I'm still have some issues with this one. I'd like to have a all of my analog inputs inside a drop down box on the front panel (one box for each axis). The user would be able to select which input they wanted on a particular axis from the drop down boxes. This would all be on the fron panel of course.
I found one good example (Signal Generation & Processing.vi) located in NI > Labview 7.1 > examples > apps, but I can't quite follow the sub-vi's. Note that I'd like the selected signals displayed on the X-Y graph to be real-time, not from logged data. Is an X-Y graph even the best plot for this? Thanks for the help ahead of time!

Are you sure you want an XY graph? An XY graph will take your two inputs and plot them against each other, not against time. If this is what you want, here's a VI that has four different inputs simulating four acquired channels, and lets you select which of the four you want for both the X and Y axes.
