it is because that property node is autoscaling the x-axis you need to scale the y-axis

Harold,

 

Try not to post a VI that is set to autorun when loaded. It makes me nervous whenever a program starts before I have a chance to look at the block diagram.

Thank you Harold for the Code...

but iv seen it already in the link i have posted in the topic.

 

it doesnt seem to work,

1. iv put off the while loop.

2.iv linked the graph instead of the example wavform to the one i want to autoscale.

 

kept the case as it is

 

result: the program doest flow... only when i press the autoscale it change.

before that autoscale change, the program was running all the time.

 

and another thing: it still does not shrink the X scale to fit a proper view of a sin wave like real instrument do.

iv post my VI here

 

i think both files needed to run properly

Here is what  i have added.

 

p.s

 

i cant really use 2 while loops in the Vi right? anyway , i called support and that was their suggestion to not complicate my VI

 

WHAY AM I DOING WRONG?

Without seeing the actual code, my guess is that what you've done wrong is not wiring a timeout value to the event structure. Without that, you don't exit the event structure to run the code outside. Instead of an event, you could have used a simple case statement wired to the Boolean.

Im not sure i got what you said about the TIME OUT thing...  and i didnt connect anything to that TimeOut, i just copied the code Harold put here... and the TImeOut thing was there already.

 

Ill be more specific in what i want to achive..

 

i added a screenshot of the simulate signal im generating...

 

im sure there is a way to creat AutoScale button that gonna change the X scale so the signal wont look so dense...
