    Dear all,

    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.

    Nicolas

    *** using gnuplot 4.2.5  ***
    gnuplot script used:

    set dgrid3d 30,30
    set hidden3d
    set pm3d
    splot 'data.dat' u 1:2:3 w l

      Dear all,

      It seems that I had numerical errors which overestimated the corners values, now it's fine.

      sorry for the inconveniance.
