sequence programming in a diagram as a control element

Hello,

i want to program a sequence in a diagram. That means (for example on x-axis: time on y-axis: frequency): a frequency begins at time 1sec with 3 Hz ... then i set a point in the diagram at x 1 and y 3.

The frequency will raise and at time 10 sec it will be at 10 Hz ... so i set the second point at x 10 y 10. etc. A line will be drawn from 1,3 to 10,10.

Then i set a new point for the new frequency and time etc.

Maybe i'm searching for not with the right words, but i couldn't find a similar example for this as a control element in LabView.

Does anybody have some ideas how i can realize this in LabView?

Thanks in advance.

best wishes

Erik
