This is a followup to my previous message. I tried various scalings
for the second graph, and I finally got correct results.

The culprit is to be found in plot/text.m, around line 147:
atstr = sprintf("%f,%f", position(1),position(2));

str = sprintf("%f", 1e-9) 
results in ... 0!

The following patch seems to work for me:

   if position(3)!=0,
-    atstr = sprintf("%f,%f,%f", position(1),position(2),position(3));

   else
-    atstr = sprintf("%f,%f", position(1),position(2));

   endif
   command = sprintf('gset label "%s" at %s %s %s %s%s',
                    str, units, atstr, align, rotate, font);
