Hi Doug,
The number of points store for each live PV data is 40000 points.
This is currently hard coded at that value.

For the next release I can certainly increase this value and/or make 
it controllable via an environment variable.

Subject: QEgui strip chart question

Hello,

I'm running a test setup for the QEgui tools as a possible replacement for
the EPICS striptool. The strip chart runs perfectly except for one issue.

The data cuts off after a certain amount of time depending on the number
of channels I am plotting. This is only live data haven't tried the
archive look up yet. So for one channel I get about three days of
plotting. For nine channels I get about one and a half hours. I assume
this has to do with a buffer setting somewhere but after days of searching
I have not been able to find it.

Any help would be greatly appreciated.

Thank you in advance,
Doug Lormand
