[rrd-users] Different data on the same graph

[Piers Kittel]

Hello all,

Have started a new RRD for system sensors (CPU temp, mobo temp, CPU  
fan etc) and have made a graph for temperatures only, and I'd think  
it'd be interesting if I add in a line showing load averages (I  
already have recorded this for 2 years or so) as the higher the load  
average, the higher the temps are.  Anyway, I've made a graph with  
all 3 data - CPU temp, motherboard temp and load average.  Obviously  
the graph has a y axis of 0 - 50, so load average is almost a flat  
line at the bottom.  Here's what I mean:

Is it possible to have the load average line on the sensors graph to  
look like the one in the load average graph?  I.e. have 2 Y axis (not  
sure of the technical name for this, sorry), one on left and one on  
right, the lines refer to whichever one is relevant, a bit like this  
one http://www.scielo.cl/fbpe/img/imar/v31n2/pag49.jpg ?

Thanks very much for your time!
