Export data from a bunch of rrds. Specify a prefix per rrd to be put onto legend. Note that each rrd *must* have the same timestep and have been updated at the same time, and *must* have homogeneous rras too. If not, those that dont look like the 1st one will be silently dropped. The export format is the rrdtool 'xport' format.
