[Gnuplot-info] plotting sparse 4D data

[Ben E. <bj...@ai...>]

Hi.

I want to use splot to plot some 4D data (x,y,z,temp) uisng the pm3d
style:

   set dgrid3d 10, 10, 10
   set pm3d
   splot 'foo.data' notitle with pm3d

I used dgrid3d to try and construct a gridded data set, but it didn't
work.  I got:

  "foo.gnuplot", line 5: Gridding of the color column is not implemented

What other options are there for doing this?  I would really like to
do it all inside gnuplot and not have to do manual processing of the
data file.

Thanks,
Ben
