A Thicker Gauge Needle?

[Justin Goeres]

As a relatively new LabView user, I'm a little stumped by some of the uses
for 'Attribute Nodes' and such. Hopefully this isn't too obvious a question:

I would like to programmatically change the thickness of the needle in a
gauge, but I can't find an attribute node selection that lets me do it.
Am I going about it in the right way?

Actually, just being able to replace the skinny needle with a thicker one
in a gauge (indicator) would be enough for my current application. I've
tried the "Edit Control..." environment, but when I try to select the thicker
needle from the "Picture Item" popup in Customize mode, it doesn't do anything!
How do I accomplish this?

Note: just importing a bitmap of a thicker needle is not an option in
this
case -- I need to be able to change its color programmatically, something
that I do not believe I could do with an imported bitmap.

Thanks in advance for any advice!

The attribute node will not help you any in this case

I tried this also with the same results. My feeling is that this control is
composed
of other controls. The needle being part of a sub control (if you will believe
that).

Not sure about this.

Go in the control editor with the control and add a second needle. This
needle will be thick.
Copy the thick needle pict to the clipboard. Undo the changes to revert to a
single needle.
Import the thick needle "at same size" in place of the thin needle. Exit the
control editor.
It is done.
