Unable to implement ratio control

[altenbach]

You need a series of pictures and some software that allows stitching them into an animated gif. I use corel photopaint, but there are many others (do a google seach for "make animated gif").

(But please simply attach your VIs. Everybody will be able to open them in any newer LabVIEW version.)

OK, thanks. I know how to do this using photo software. I thought maybe there was some feature of LV capable of this that I was missing.

Here I am attaching the VI. I have done just the same thing but my VI is not running. Strange indeed!

What is going on in your false case?

You start a calculation, but then don't do anything with it.  Then you proceed to output a default array which means it is empty.  That breaks all further use of your VI.

In addition to Ravens solution, you also should change the cluster size to 4 for "Array to cluster" (right-click...cluster size) to eliminate the 5 extra chart traces at zero.
