NagiosGrapher Question

Could you explain why the values on the side of the graph don’t correlate to the Latest load averages shown below?


Found the problem in check_load.ncfg. 15min load set to rrd_plottype AREA; 5min rrd_plottype STACK; 1min rrd_plottype STACK. This was causing the values to be added together. I changed to rrd_plottype LINE for all and is displays correct values. But is not as visual appealing as the are graphs.
Is there a fix for this?
