Hi Tva !
There is little chance that you could get help from people taht disappeared from the LV forum in 2002 !
Modifying a control/indicator is not that difficult : Here, a simple gauge control was used. A right click on the control gives access to some possible modifications, such as adding a needle, or changing the scale display (add minor scale ticks). Then you can rotate the scale position : just fly the mouse pointer over the scale and you will see that it changes for a circular arrow. Click and you will be able to move the scale.
Deeper modifications can be achieved by editing the control : select, then go to menu Edit>Customize control...
refer to the LV help to get more infos.
