can slide color vary with number indicated?

[jilla]

Hello,

I have a slide indicator that I would like to use to indicate cylinder head temperature. When I right click on it and select "properties", I am allowed to select a fill color, but I would like for the color to change with the temperature indicated, ie: green for 0-400deg, yellow for 400-500 deg, and red for >500deg. This appears to be an option on meters - is it also on slide indicators? Thanks.

Simply create a property node for "Fill Color". Now create a case structure for your condition in front of the property node and place the appropriate colorbox constant in each case. Wire them the property node. See how far you get. 🙂

thanks guys,

i was just stumbling onto property nodes. so much to learn. thanks again.

Here's a more streamlined version using a case structure with ranges (LabVIEW 8.0). Also remember that if all cases of a case structure contain the same property node, the property node itself belongs outside the case structure.

(I also made the slide an indicator as apparently desired. ;)) Remember that property nodes are relatively expensive, so it might be worth to place it inside another case structure so it only gets written when the color actually changes, and not with each loop iteration.

Here's another alternative. Sometimes, the code is easier to read, edit, and debug if you simply index into a lookup table of colors.

Now all code is completely visible and noting is hidden inside cases.

Try it!
