Is there a way to modify needle thickness in dial controls -(in CVI not LabView)

Hi,

Unfortunately there is not a built in way to change the needle in the knob; however there are a couple of things that I can recommend here:

+use the Measurement Studio ActiveX knob control. This control does not allows for a thicker needle, however it allows you to fill with color to the minimum or maximum value. The control will be a bit harder to program that the CVI controls, but the ActiveX wizard make things fairly easy.

+use a mixture of a knob and a gauge indicator to emulate a knob with the thicker needle. You overlay one on top of the other and make some components transparent. You can end up with a nice looking knob with a bigger needle.

Please take a look at the example UIR that I'm including here. Let me know if you have any fu
rther questions on this.

Thanks. The invisible gauge control is very helpful.

If you want this as an indicator only you could also put a transparent picture control where you draw a line of the thickness that you need on top of the needlr.

Just another option.

good luck with your project.
