adding autoscale button

[Eldad]

hi

im trying to add an AutoScale button to both X & Y scales of my graph.

i know about the right click and x scale, y thing.. but i wang the user to have AutoScale button.

i also tries this:

and the vi that comes with it.. but it doesnt seems to do the job.

any suggestion?

[Eldad]

i must say im also familier with visible Item->Scale Legend

it doesnt seem to do the job when i use high frequencies...

[Harold_Timmis]

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

here is the code:

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.

[Harold_Timmis]

lol sorry I modified this code and forgot to take that out

[Eldad]

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...
