gnuplot: How to plot homogeneous spheres in 3D with different diameters?
问题 I want to make a 3D representation of a large number of spheres of different diameter using gnuplot and whose information are in a file called 'data.dat' . If I do: splot 'data.dat' u 1:2:3 w p lt 7 I get a series of points of small dimensions of a homogeneous color. How can I add the real size of the spheres (read from the 4th column of the file 'data.dat' ) using the splot command? Something like: splot 'data.dat' u 1:2:3:4 ... 回答1: Since gnuplot 5.4, I guess you have the plotting style
