Munin / rrdtool how to create graph with Y axis has different down and up scales

graphrrdtoolscale

It is possible to tell MUMIN plugin draw graph with different up and down Y axis scales? I looked for this on Internet but found nothing. I read mumin docs, but this points to RRDtool docs. In last one I found nothing.

RRDTool (as of version 1.4) does not allow you to have different scales on the Y-axis above and below.

What it does allow you to do is to create a secondary Y-axis with a scale shift argument. Items are still plotted according to the primary Y axis, though, so you need to perform any necessary calculations yourself. The necessary parameter is --right-axis.
