Previously posted as how to graph numbers significantly smaller than 1, but greater than 0.

I've added:
push @params,'--alt-y-grid' if($RRDs::VERSION >= 1.2);

I'm not sure when the feature was added to rrdtool, so I put the restriction that it must be at least 1.2, but this allows me to use the 'rescale' function in routers2 to get the y-grid to step dynamically in terms of values like 0.00008 to 0.0001 and so forth.

The only thing would be to have routers2 realize the value of the graph and choose the correct scale automatically, but this might be a bit too much to ask.

v.2.20 now has a new option in the oruters2.conf, 'altygrid=y' to enable this sort of behaviour.
