I need to look at my custom graphs with a higher resolution (shorter timeframe) than the default "Last 48 hours".
I tried the changes below in hobbitgraph.cfg (appended ":start=end-4h" to the DEF entries), but this didn't make any difference. I was attempting to get a "Last 4 hours" display.
... [recent] TITLE Incoming Cases YAXIS Count DEF:five=recent.rrd:five:AVERAGE:start=end-4h DEF:ten=recent.rrd:ten:AVERAGE:start=end-4h DEF:fifteen=recent.rrd:fifteen:AVERAGE:start=end-4h DEF:twenty=recent.rrd:twenty:AVERAGE:start=end-4h ...
I also tried "end=start+4h", not expecting that to give me what I wanted, but as a test to see if I could get a four hour window displayed. This directive appeared to be ignored as well. The display always shows "Last 48 hours".
