I don't have any definite solutions to offer, but just thinking out loud, you could try using the "first" and "count" parameters in the graph URL when you want to see a graph with only that one data source in it (which should then scale correctly). You could also try specifying options in hobbitgraph.cfg to change the way the graph is displayed (check the rrdtool man page), by either setting a max height, or changing the scaling options.

Hello,

is it possible to create two (or more) custom graphs using the ncv to create it? My problem is that the values differ so much so one line in the graph always appear as a horizontal line. I've tried to create a second entry in hobbitgraph.cfg for the same test but only the last graph in that file appears.
