Controlling Graph/Control with start/stop button

[iCamps]

Hi all,

I am new to LabView. I am trying to control a measurement (simulated here as a graph) whith a start/stop button.

What I am trying is:
1-) The start/stop button is disable when the VI began (I put the VI as Auto-Run)
2-) I change the parameters (Vo, Vf, NPoints)
3-) I choose the type of ramp (Up or Down)
4-) I click the start/stop button and the graph (or the measurement) appear.

One the start/stop button is active, the ramp type control selector must be disable. If I would like to change the type of ramp or the initial values, I should stop (clicking the start/stop button) the process.

Here I attach what I did so far.

I will really appreciate any help.

Thanks in advance,

Camps
