When you started using RRDtool you noticed the graphics were not
made anymore.  You needed to use another program to do that.

14all is such a program, it is 14all that is now generating your
images.  However, the design goal of 14all is (as far as I know)
to provide MRTG compatible images.  You want to have some different
program so you need to use some different program.

If you go through my tutorial (it's in the doc dir) you should be
able to generate your own grapher scripts.  You need to have some
programming experience but it shouldn't be too hard.

It is possible to fetch data from two MRTG compatible databases
and plot this data onto one graph:

   rrdtool graph /path/to/imagedir/mygraph.png -A PNG
