[Octave-bug-tracker] [bug #35144] trisurf.m demo failure

[marco atzeri]

Follow-up Comment #4, bug #35144 (project octave):

both. With gnuplot, I get the error and no plot

octave:1> demo /usr/local/share/octave/3.5.90+/m/plot/trisurf.m
/usr/local/share/octave/3.5.90+/m/plot/trisurf.m example 1:
 clf
 old_state = rand ("state");
 restore_state = onCleanup (@() rand ("state", old_state));
 rand ("state", 10);
 N = 10;
 x = 3 - 6 * rand (N, N);
 y = 3 - 6 * rand (N, N);
 z = peaks (x, y);
 tri = delaunay (x(:), y(:));
 trisurf (tri, x(:), y(:), z(:));

error: __go_draw_axes__: operator *: nonconformant arguments (op1 is 0x0, op2
is 3x1)
error: called from:

The error arises from trisurf call
