I think you have got me here.The only thing I can see that's "odd" about your graph definition, is the lack of %s at the end of each gprint line, which isn't essential, and only impacts scaling, and the \n at the end of the last line.The /n will impact the appearance of the text at the bottom of your graph, but shouldn't mess up your lines.Even without the gprint statements, you still should get a graph.

How are the rrd files being generated?If it was me, I would double check every rrd file to make sure we have the correct internal field name (my first thought) and then check that each one has valid data. I have seen situations where the rrd file ended up with 2 fields due to badly formatted data coming from the client. I had the correct field and a gibberish field name. The real data was going into the gibberish field, and the correct field was going unpopulated.Also check you debug logs to see if there is a problem with the display/rendering of the graphs.

Hi Keith
Your internal field name is memused.
Is that correct for all the rrd files?This is the field name as defined in the rrd file. 
Check how the rrd file is created, or use rrdtool dump with some creative grep to confirm the field names.

Do you get a graph without the EXFNPATTERN keyword? (A long shot, but might be worth checking)

If you know the rrd files in advance, and you know the number of them, and it will not change, then why not define them manually.It's a little more of a pain up front, but it might save you a lot of grief.Check [users], [vmstat*] or [netstat*] in graphs.cfg for examples.

I have three rrds: ProcMBIM.rrd, ProcSA.rrd, and ProcOI.rrd
The definition I have in graphs.cfg is
FNPATTERN ^Proc(.+).rrd                NOTE: also tried (.*) - no differenceEXFNPATTERN ^ProcMem(.*).rrd    NOTE: for one specific rrd created i don't wantTITLE Process Memory UsageYAXIS Total Memory UsageDEF:p at RRDIDX@=@RRDFN@:memused:AVERAGELINE2:p at RRDIDX@#@COLOR@:@RRDPARAM at -b 1024-X0GPRINT:p at RRDIDX@:LAST: \: %5.1lf (cur)GPRINT:p at RRDIDX@:MAX: \: %5.1lf (max)GPRINT:p at RRDIDX@:MIN: \: %5.1lf (min)GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)

I get a graph in trends, but ONLY for MBIM. SA and OI not shown.
I get NO graph on the page itself.
So any help appreciated - I imagine I must be missing something to cause these two issues.
