I want to make a curve spline with points like excel but gnuplot 5.2 doesn't have the option "smooth path". I can see that the version 5.4 or 5.5 have the option "smooth path" but I could not install that versions. Someone to help me?
Linux version is available at
https://sourceforge.net/projects/gnuplot/files/gnuplot/5.4.0/
Development version
git clone https://git.code.sf.net/p/gnuplot/gnuplot-main gnuplot-gnuplot-main
Under Windows, you should not build it from the source files, and just download the ready-to-install package (a normal Windows installation), but this is not true for the very last version (5.4.0). If you need features from the 5.4 version, and don't want to build the executable file from the sources, then you should wait for the executable file to be downloadable (they say this will happen, sooner or later).
