#2145 — Splot 3d data with interpolated pm3d colors at b

Hi,

I'd like to plot a simple 3d mesh (uncoloured surface plot) with interpolated pm3d colors at bottom representing the same data. Thus, I typed in:

set dgrid3d
set pm3d at b interpolate, 30,30
splot 'file.txt' w l

But all what I get is a coloured surface plot. What's wrong, where's the mistake and how can I fix it.

Thanks for help!

I can pretty much guarantee that you don't want "interpolate 30,30".
That instructs the program to break each rectangle of the mesh into
900 subrectangles, eating up lots of CPU time but accomplishing very
little.

But yes, it does seem that giving any interpolation values other than 1
has the unintended side effect of cancelling the "at bottom".

Ok, maybe 30,30 is a bit too much.

But I assume that there should be any solution to this problem?

Issue your default splot command and  make a note of the Z coordinate
of the xy-plane at the bottom.  Let's say it's ZBOT.
Now replot as below forcing the pm3d-colored surface to lie in this
plane.


ZBOT = <whatever it was before, or your choice of something else>
set pm3d interpolate 3,3 noimplicit
set xyplane at ZBOT
splot 'data' using 1:2:(ZBOT):3 with pm3d, '' using 1:2:3 with lines

Sry, don't really understand. If you mean with ZBOT the values of my Z coordinate, then it doesn't work (Gridding of the color column is not implemented).
