Spacing between points in graph in gnuplot

3D graph

As can be seen in the picture attached, the points become too cluttered after a certain point. How do I increase the spacing between points in that region? Code:

set term jpeg size 1800,900
set output "plot.jpeg"

splot "3d_ME2_31.out" us 1:2:3 lc -1 

set grid

set output

I have tried the "every" command but it increasing the spacing in the beginning region too where the point spacing is already high.

Any advice is appreciated. Thanks !

Edit: Data file ( the data to axes mapping is 1:2:3 )

Solution

  • I would say whether your data points look cluttered or cramped does not only depend on your data but also on your viewpoint. If you have so many data points why don't you simply plot it with lines? Or as Ethan suggested with linespoints and a certain pointinterval or pointnumber (check help lp).

    Script:

    set multiplot layout 2,1

    set view 60,30
    splot $Data u 1:2:3 w p pt 1

    set view 71,333
    splot $Data u 1:2:3 w p pt 1
unset multiplot

    Result: (same datapoints just different viewing angles)
