Access needles on a Gauge with two needles

[santima570]

I have a gauge on my front panel with a single needles. When I added another needle, the gauge indicator on the block diagram changed to a cluster type. I need to access each needle and perform operations on them. I tried using the "unbubdle" funciton but it did not work. How do I access both needles ?

Use the Bundle function (instead of Unbundle) to set the values of both needles…

The needles are being driven already by another value. To be more precise, I need to create a knob reference of each needle but before that I need to be able extract each needle from the cluster having those two needles.

Could you provide the VI that you are having problems with?  I have no idea what you are talking about.  A picture is worth a thousand words, and a VI is worth a thousand pictures, so you can see that it would be orders of magnitude easier for us to provide help if you provided the VI rather than rely on a complicated description.

It's really not clear what you want to do; but I'll take a wild guess that you want to create references that you can pass to a subVI that will allow the subVI to access the values of the needles.

This is exactly what I was trying to do. Thanks !
