Follow-up Comment #2, bug #45593 (project octave):
The following code is what complains and the pm3d style of gnuplot is used:
if (numel (xcol) > 3)
error ("__go_draw_axes__: gnuplot (as of v4.2) only supports
3-D filled triangular patches");
else
if (isnan (data_3d_idx))
data_idx++;
data_3d_idx = data_idx;
is_image_data(data_idx) = false;
parametric(data_idx) = false;
have_cdata(data_idx) = true;
have_3d_patch(data_idx) = true;
withclause{data_3d_idx} = sprintf ("with pm3d");
usingclause{data_3d_idx} = "using 1:2:3:4";
data{data_3d_idx} = [];
endif
local_idx = data_3d_idx;
ccdat = NaN;
endif
If one were to write the above to use triangulation of polygons, it would be
possible to use pm3d. However, a more straightforward approach might be to
use gnuplot's polygon object. As an example:
set object 1 polygon from 2,2 to 3,2 to 3,3 to 2,3 to 2,2
set object 1 fc rgb "cyan" fillstyle solid 1.0 border lt -2
set xrange [0:10]
set yrange [0:10]
set zrange [0:10]
splot 1/0
