You mean you convert one set of values to negative (or collect them
that way) so that they plot down from teh X axis, but you want the
value printed in teh legend (with gprint) to be positive ?

Just modify your definitions, eg if both are positive values then :

value1=<some rrd selection>
value2=<a different rrd selection>

value2b=value2 * -1

plot value1
plot value2b

print value1, value2

So you print the positive value2, but plot the negative value2b
derived from it.
