我试着像其他帖子中建议的那样去做。但是这些点没有打印出来。我的错误在哪里:
set decimalsign locale
set datafile separator ";"
set table 'point_data.dat'
unset dgrid3d
splot './points.csv' u 1:2:3
unset table
#set pm3d implicit at s
#set pm3d interpolate 1,1 flush begin noftriangles hidden3d 100 corners2color mean
set dgrid3d 50,50,50
set output 'field.pdf'
splot './point_data.dat' u 1:2:3 w points pt 7, \
'./field.csv' u 2:1:3 with lines lt 5 lc rgb "#000000"
set output
exit
