The loadpath setting defines additional locations for data and command files searched by the call, `load`, `plot` and `splot` commands. If a file cannot be found in the current directory, the directories in loadpath are tried.
Syntax:
set loadpath {"pathlist1" {"pathlist2"...}} show loadpath
Path names may be entered as single directory names, or as a list of path names separated by a platform-specific path separator, eg. colon (':') on Unix, semicolon (';') on DOS/Windows/OS/2 platforms. The loadpath, save and `save set` commands replace the platform-specific separator with a space character (' ').
If the environment variable GNUPLOT_LIB is set, its contents are appended to loadpath. However, loadpath prints the contents of loadpath and GNUPLOT_LIB separately. Also, the save and `save set` commands ignore the contents of GNUPLOT_LIB.
