Hi Peter,

You can use XY Graph widget in BOY. Set "Y PV" as your waveform PV
and set "Concatenate Data" to false.
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Yes, of course. That makes sense. At first there was this display that seemed to do nothing, then after a few minutes it morphed into a huge scrolling ..concatenation.. of all the data that had gone past.

Shoulda asked earlier, my waveform source is now c/o FEDEX.


See /BOY
Examples/Miscellaneous/ArraysOperation/PlotFirstNPointsExample.opi

Great, looking forward to trying this

Thank you!

FAQ: howto plot a live waveform record cartesian plot

Hi Chen

Is there an example of this?. In a recent demo, I'd success
plotting a live scalar PV to a stripchart with CSS data browser,
but no joy in getting a live waveform record to plot (refresh
1..10Hz, complete redraw each time, like a scope). Luckily for me
the MEDM cartesian plot still worked fine, but I'd far prefer to
have it all under CSS.

If we have to create an an actual OPI/BOY display to do this, that
would be OK too, but an example to copy would be helpful.

Thanks

Peter
