[Octave-bug-tracker] [bug #49194] Surface color incorrect under gnuplot 4.4.0

[Mike Miller]

Follow-up Comment #7, bug #49194 (project octave):

I get a slightly better looking plot with this change applied, but I now get
the following error messages printed to the terminal:


>> graphics_toolkit gnuplot
>> demo waterfall 1
waterfall example 1:
 clf;
 colormap ("default");
 Z = peaks ();
 waterfall (Z);
 title ("waterfall() plot of peaks() function");


gnuplot> if (GPVAL_TERM eq "qt") {set obj 1 rectangle from screen 0,0 to
screen 1,1 behind fc rgb "#ffffff" fs solid noborder}
                                 ^
         line 0: invalid complex constant

>> 
gnuplot> unset obj 1;
                    ^
         line 0: object not found



These messages did not appear before, when the surface had a yellow
background. Now there is no yellow, but the surface is transparent instead of
opaque as it is under gnuplot 4.6 or 5.
