[Gnuplot-info] assign fixed color to each Z-level

[sikp <si...@se...>]

Hello,

is it possible to create 3d graph like this in gnuplot?

I need fixed color for each Z-level 0-1, 1-2 and so on..

Thanks, regards,
 Petr

you could define a color palette with discrete colors:

set cbrange [0:6]
set palette defined (0 "white", 1 "white", 1 "green", 2 "green", 2 "yellow",
3 "yellow", 3 "orange", 4 "orange", 4 "orange-red", 5 "orange-red", 5 "red", 
6 "red")
# have a look at the palette
test palette
pause -1
# do a test plot
splot 3.*(x+y) with pm3d

Thanks, I have tried, but the result is different :-(:

http://old.nabble.com/file/p31976182/test.png 

My input is data file:  http://old.nabble.com/file/p31976182/data_test.txt
data_test.txt 

I use this command to plot it:
 splot  "data_test.txt" with pm3d

Thanks, Petr
