[Gnuplot-info] Plot with pm3d - hidden3d and line colours

[crashdum <fre...@cl...>]

Hello,

I'm quite new to gnuplot, and I have a question regarding a feature of splot
with pm3d.

I want to plot different 3d data (using dgrid3d) on a same graph (four
different surfaces that can be intersecting each other). 
I use the splot with pm3d in order to plot the four surfaces, and with set
pm3d depthorder, gnuplot manages nicely the surfaces drawing, as if there
was a z-buffer.
I also use transparent fill so we can see through each surface.

Now, I want each surface to have a wireframe on it. I use set pm3d hidden3d
<linestyle>  in order to do so, but in this case, all my four surfaces will
have the same line color.
However, I would like the wireframe of each surface have different colour.
How can I define different pm3d styles that I could use after during splot ?

Something looking like  splot "mydata" u 1:2:3 with pm3d style 1, '' u 1:2:4
with pm3d style 2, ...

Is it possible ?

I can of course plot one surface, change the style of pm3d, and then plot a
second surface... But, in this case, the ordering of the surfaces is no more
correctly made (the last drawn surface is on top of all the others).

Thanks in advance for any help,
John

My Gnuplot is Version 4.4 patchlevel 0-rc1
