Hi Rupali,

I think you need to clarify a bit.

• Do you mean, you need sort of Alpha blending for your indicator?  
• What kind of indicator is it?
• Why is the visibility property not appropriate?
• Why do you need it transparent (I never came to this problem)?

The VI I'm working is for testing machine.. And it is needed that the operator should be able to see all the indicators... That's why I don't want to use visibility property.. I don't want alpha blending for this.. It's a simple indicator that you can find on function as square LED... I have changed it's on - off color.. When the decision is true it will be on showing green color and when it's false it will be off showing red color.. But when there is no decision means during testing I want those indicators to be transparent... Is there any solution for this..?

You can modify the color at runtime by writing to the Colors[4] property.

As long as there is no decision make sure the value is false and set the false color (index 0) to transparent. As soon as there is a decision, change the false color to red and set the boolean value.

If you just use it as a status indicator it might be simpler to use a color box indicator and write the color value to it.

Can you please show me how to use colors[4] property.. I tried that one also but was unable to get desired output.. 😞

The attached code shows how to make the false value transparent.

To use the color again, replace element 0 with red.
