[Octave-bug-tracker] [bug #35761] surf() fails when Z values are within eps of each other

[Marco Caliari]

Follow-up Comment #8, bug #35761 (project octave):

Rik,

probably you are right, it is just a problem of gnuplot. Restoring graphics.cc
at the original state and changing


fprintf (plot_stream, "set cbrange [%g:%g];n", clim);


with


fprintf (plot_stream, "set cbrange [%.15e:%.15e];n", clim);


around line 1440 of __go_draw_axes__.m, I get all the examples mentioned in
this thread working. In that file, three lines above there is a similar one
that probably should be changed, too. Can you confirm that *both* lines should
be changed?

Thanks,

Marco
