Is it possible to change color of slider on different values?

Question

I'm trying to set up an instrument that receives data from a sensor. My idea is to show a sliders with the values read and accordingly  represent acceptable levels in one color and whatever is above it on a different color (lets say green and red).
Any ideas would be appreciated.

You're going to have to use a Property Node for the slider to change it's color.
The attached VI shows a simple example of how to do this.
Right click on the indicator and select 'Create>Property Node'.
Right click on the property node and select, 'Change to Write'.
Right click on the node again and select 'Properties>Fill Color' (or other property you want to change).
Create the logic to watch for the value over limit.
You do have to be careful using property nodes. They are very useful,
but they also have a performance hit on your application. You should
construct a way to only write to the node when you need to change
something. Constantly writting the same value to the node (as my quick
example is doing ) is not good programming practice.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
