I am trying to do a 3d surface using pm3d to color the surface by the 3rd componant of my data file.
Everything is working well, but I have problems in the corners where the interpolation is not efficient. Consequently, the z-scale is false and the surface is flaten due to the corner values.
Do anybody has hint to solve this isue?
Thanks in advance.
*** using gnuplot 4.2.5 ***
gnuplot script used:
set dgrid3d 30,30
splot 'data.dat' u 1:2:3 w l
It seems that I had numerical errors which overestimated the corners values, now it's fine.
sorry for the inconveniance.
