hidden3d, linetype and linestyle

[Hagen W. <ha...@gn...>]

Hi,

the customization of the linetypes seems to have some implications on the
behavior of hidden3d.

Consider the following example:
set style line 1 lc rgb 'gray'
set parametric
set mapping spherical
set angles degrees
set urange[0:360]
set vrange[-90:90]
set isosamples 25
splot cos(v)*cos(u),cos(v)*sin(u),sin(v) w l ls 1

Until here, everything looks fine. Now we hide some lines.
set hidden3d
replot

The gray color of the plotted line has changed to red. In order to manage to get
the gray lines back, we have to apply the following commands:
set linetype 1 lc rgb 'gray'
replot

Is this behavior intended? It is not obvious that I can't use linestyle with
hidden3d, but have to use linetype to set the color.

Best regards,
Hagen
