Hi Himanshu.

Yes, you can do this CSS BOY using a script. Firstly, you put a local pv for X PV. In the script, you can write whatever value you want to this local PV and stop writing after 5 for example. Then you can configure the trace to update on X PV only.

Thanks,
Xihui

Subject: Re: Relative time in XY graph

can we do this in control system studio also?

i have another question from where does the waveform PV gets its time for plotting in XY graph?
i am plotting a PV of waveform type record but I am somehow getting the wrong time displayed in graph.
please suggest

at least in EDM there is a TriggerPV somewhere in the grap settings that
should do what you describe. Down side is that your graph gets updated
even if the value hasn't changed.

The trigger pv could be a calc which gets updated every 1 second and
counts up to 5 where an additonal condition stops the counter/trigger-value.
