The issue here is that EDM (and all other channel access clients of which I am aware) only make a get request for graphic information at connection time to limit the amount of network traffic. This has been on the list for a long time - the ability to monitor the metadata and get a dbr_graphic_double only when the metadata changes and get the value, time stamp status all other times.
What is the display limit field being used to do? I thought that all array plotting tools had scaling available through the display.

Subject: another question on custom record stuff
I have a field that is an array
And with that field I have the get_graphic_double routine that gives out
the limits for that array.
Now I have another field that is actually the limit.
So the get_graphic_double routine simply puts that field inside
upper_disp_limit
And it work well the first time.
Now the problem is that if I change the limit field then well.
MEDM just doesn't know about it.
So how do I get that part to run again?
Or is this another one of those impossible things :(
