The smaller this number, the more rough mesh you get. The zero value is the default threshold for values approaching 0.

Executing the gnuplot program file will open a command line program. Gnuplot will not plot a point if its imaginary part is greater in magnitude than the zero threshold. Converting this plot to a twodimensional map style view like a plan view of the current plot, and sometimes known as a raster plot, can be done with the set view map command try it with the plot above, without changing the other commands. Thread view gnuplotinfo splot 3d vectors given in component form. Version contents index view the set view command sets the viewing angle for splots. Gnuplot is a portable commandline driven graphing utility for linux, os2, ms windows, osx, vms, and many other platforms. Gnuplot is used by other projects as a graphing engine. In the splot, the zeropoint of zaxis is placed above the xy plane. Gnuplot draws 3d figures with lines and or points, in addition, ver.
