Is there anyway that i can make a boolean value display 3 different states?

[havok]

I'm building a vi frontpanel to simulate water and air flowing through a system. problem is that  the wate and air flow through the same pipe at different times and i'd like to show this. Is there anyway it can get the boolean variable to display two different colours in the TRUE state. ie one for air and the other for water.

Hi havok,

a boolean indicator is limited to two states. But you can change the properties of each state (including color) by using property nodes.

But then it could be easier to use a color box instead!

Hi,

You can change the color of a boolean indicator with a property node

You can use the Color Box from the numeric palette to display different colors. For shapes other than rectangular you can mask the color box with some decorations. If you want to display predefined images you can use the picture ring.
Hope this helps,
Dave

This link shows one way to use a combination of the ideas given above.

You are displaying the state of two different objects.  Why not use two LEDs side by side?

Anything that has more than 2 states is no longer a boolean! 😮

Just use a "colorbox" LED and assign colors to all the states you want, then select the state with e.g. a number, ring, enum, etc. as desired.

Here isn an old example: 4ColorLED.vi (modify as needed. For more details, check out the old thread).

If you have LabVIEW 8.0 or higher, you cold even make an Xcontrol.

Thanks guys. I actually ended up using a combination of the ideas you guys gave me. I used two booleans placed one on top of the other with different colours used to indicate the water and air and i used property nodes to make one boolean invisible depending on what i wanted to indicate as flowing throught the system
