Display partial data graph with numeric control and cursor!

Hello,

I have problem to fit the ida to use numeric control to fix partial data to show in another graph from data graph entry file.

With numeric control it works ok. I fitted to no over range from data input.

I would like to can choose the data to show in the bottom graph with both controls and cursors, but I dont know the best way to get it. I tried but I only can get works it in both case separately.

Check vi attached I believe it shows clear the idea I want to get.

Any help would be great!.

Thanks for all guys.

Regards, Fred.
