Visible/invisible property nodes


My question is somewhat complicated...For my program I have Labview connected to a force plate through an invoke node. When the forces on the force plate reach a certain threshold I want Labview to display 1 of 10 different indicators on the front panel. I've designed my program so that a random number generator picks which indicator will be displayed. I created a case structure that has 10 different cases to make all other indicators invisible and to just show the one that was randomly selected.

The problem is that I only want Labview to display just one indicator. For some reason when I run the program Labview is constantly polling the force plate data, and it gives me mulitple indicators, even before the force plate reaches the desired threshold. I tried using a stacked sequence to make sure that the random number generator doesn't fire until the threshold is reached, but for some instances Labview will show 2 indicators on the front panel by flashing one quickly, then finishing on another.

Does anyone have any suggestions as to how to get Labview to only show me one indicator?

you may use

- a tab container with 10 tabs/pages, each with a single indicator on it. Just switch the pages...

- a picture ring with 10 pictures. Just switch the ring...


How fast/often do you switch the visibility of all those indicators?

I want them to be invisble at the start of each trial, and then when the threshold is reached I only want Labview to make one visible. Some times it works as I would like, but other times it doesn't not. I'm not sure what the inconsistancy is.

It would be a lot easier to find the issue if you post the code.

Never mind, I figured it out. I had my indicators on the outside of my case structure, and they needed to be on the inside.

Thanks for your help

You have a few problems.


#1 you just are not generating a random number between 1 and 10.

try this:


All those comparisons to DBLS aren't doing much for you either.  to enter any case integer must equal the case value. 

All the F constants can be removed too, just use default if unwired and the F is implied unless you wire T to the tunnel.


#2 why are you using 10 booleans when one would do?  You have shown you know what a property node is.  look for Text.Text, Text.Color and Colors[4]

     Forgive me for being so picky.  A Gaussian distribution (usually spelled with two s's) is also called the Normal Distribution, or "The Bell-shaped Curve".  What you generated was a Uniform distribution.

Thanks for keeping me on my toes.  Yes that is a discrete uniform distribution.  (School was a long time ago)
