Re: How to pm3d plot a kind of randomized data set

Show all headers | View raw

I have a relating question, so I'm reviving my own thread.

The Data file 3dRnd.dat is given in
x1 y1 z1

x2 y2 z2

x3 y3 z3

....

So there is an empty line between each data points.

I'm plotting it now with Karl's Suggestion
set dgrid3d
set palette rgbformulae 22,13,-31
set view map
set nokey
splot "./DATA/3dRnd.dat" us 1:2:($3<1e300 ? $3 : 1/0) w pm3d


Now I want to add the Minimum (of the z value) as a special marked area in this plot. 
I already found the stats Command , given by
stats ./3dRnd.dat' using 3 prefix A

I can also plot this Minimum area with the command
splot  './DATA/3dRnd.dat' us ($3==A_min? $1 : 1/0) : ($3 == A_min ? $2 : 1/0) : ($3==A_min ? $3 : 1/0) w pm3d

how can I make a palette that especially uses some flashy colour (like purple)  if $3==A_min and in the other cases it uses the rgbformulae 22,13,-31 ? 

Thanks for your advice.
