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.

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 :(
