graph with fixed x scale beginning

[Yves]

Hi
I'm trying to display the online data in a graph with a fixed origin and a variable end.
The x scale shows time in seconds.
The fixed origin of the x scale is 0. Within the first 15 seconds the data fills out the graph. If the acquisition is longer than 15 seconds the end of the x scale is increased while the origin ins't changed.

I hope my description is good enough.

How can I do that?

Thanks for any help.

A standard Waveform chart should do what you want.

Hmmm, somehow I'm still stuck on this small problem.
When I'm running the attached main.vi the graph is initialized correctly but the x-scale doens't stay fixed on the defined range.
WHY?

Thanks for any help.
