Problem with mesh plots and hidden line removal

[Kai H. <kai...@gm...>]

Hello,

I noticed the following problem in octave3.0.0/gnuplot4.2.2 using the wxt terminal. When I try to plot a 3D mesh with "hidden on" and a rgb color set, only the white facets without grid are drawn.

Please have a look at the script below. If I change "set hidden" to "unset hidden" a magenta grid is drawn as expected, but with "set hidden" it is not (only white facets).

Also, if I I use

'set style line 1 default;'

instead of

'set style line 1 linewidth 0.500000 pointsize 1.000000 linecolor rgbcolor "#FF00FF";'

and 'set hidden' it works as expected - a grid, with hidden line removal and the default (green) color is drawn.

Is this a bug in the script or a gnuplot problem?

Thanks in advance,
Kai
