How ot change knob range shown on front panel programmably?

[Wang Shen]

Using the property node of my knob control I can change the real data range programmably.But I want to change the data range shown on the front panel ,too. LabVIEW only limit the needle in the range I set before, but the range shown never change.

How can I change the range shown on font panel?
Thanks.

Hi,
If I've got the problem you are trying to change the range of scale shown around the knob. If so you must use the property node items from
Properties->Scale->Range

I've attached the example.

Good luck.

Hm... I've got a german Version of LV 6i here. But I'll try to translate.
I found something under Axis, Range (german: "Achse Bereich"). It's in
the submenu for the axis.
I've made a little example. You can find it on
http://marco.tedaldi.net/labview/vis/
It's named range-knob.vi

hope, i could help you a little bit.
