while loop iteration stays at 0

[marcv]

i have labview 7 student editon. i am trying to do a while loop that increments and plots a sin wave. basically i am doing chapter 1 in Advaced labview labs. but when i run it i get a line. when i run step by step it looks like the iteration is staying at 0. any ideas. thanx.

Hello, can you post the VI please ?

Well... obviously you are new to LabVIEW, don't worry we all started from the bottom just like you 😉

In the right-bottom corner of the loop you linked a TRUE constant to the "stop condition", and this stop condition is set "stop if true".
So the loop executes just once and this is normal behaviour.

Have a look at the VI attached to see how to do it differently 😉 !
