empty keys in legend

[Hartmut Wziontek]

Hello,

have a problem with empty legend-entries since I upgraded to a
new machine running under SuSE10-x86_64. Both installations
have only minor differences, both running version 2.9.3 from cvs
with gnuplot 4.0.0.

if I make a plot like
   plot(x1,y1,'0^')
I've got on the old machine no entry in the legend (which was what
I wanted), but for all following plot-commands like
   plot(x1,y1,';key;')
there was an entry for the resp. graph (using hold on).

Now, on the new machine an entry is generated in any case, also
for the 1st plot command, only with a line but without description
and I get the following warning:

warning: unknown token = """ in plot command

Is there any way around generating an empty legend entry
for a specific graph?
gset key / gset nokey is not the solution since it turns
off the legend completely, not selective for some entries.

Many thanks

Hartmut
