[Gnuplot-info] pm3d depthorder

[Dr. E. E. <en...@th...>]

Dear gnuplot specialists,

I am trying to produce plots in which spatial densities (density
color-coded) are combined with structure data (positions, lines in
space). An example for the kind of plot is attached, with the problem
reduced to the minimum. In this example

"densityfile"  using 1:2:3:4 with pm3d

is used to generate the density in a particular area of space,

"linefile"  using 1:2:3 with lines lc rgb "black" lt 1 

etc generates the additional structures around. What I do not manage to
achieve in this way is proper ordering of the various elements in space.
I am aware of the discussion triggered by user joanpau in May of this
year. For that reason I am using gnuplot 4.4.2 (on Ubuntu Lucid). Still
the pm3d element always stays on top (rotate the example to see what I
mean). Is there a way around this?


Thanks for your help!
