Re: CSS BOY Meter widget limits

[Paweł Prędki <ppredki@dmcs.pl>]

Hello,

The thing is the HIHI, HIGH, LOW and LOLO values are initialized in the 
record but BOY doesn't seem to be loading them. The record I'm referring 
to is as follows:

record(ao,DISK:FORWARDING") {
  field(DESC,"Forwarding Throughput")
  field(DTYP,"Raw Soft Channel")
  field(EGU,"Gbps")
  field(OMSL,"supervisory")
  field(DRVL,0.0)
  field(DRVH,10.0)
  field(LOPR,0.0)
  field(HOPR,10.0)
  field(HIHI,8.0)
  field(HIGH,7.0);
  field(LOW, 1.0);
  field(LOLO,0.0)
}

Maybe the problem lies here.
