Gnuplot is not plotting any points under X11! How come?
Very probably, you still are using an old version of gnuplot_x11. Remove that, then do a full installation. On VMS, you need to make several symbols: $ gnuplot_x11 :== $disk:[directory]gnuplot_x11 $ gnuplot :== $disk:[directory]gnuplot.exe $ def/job GNUPLOT$HELP disk:[directory]gnuplot.hlb Then run gnuplot from your command line, and use gnuplot> set term x11 Q7.
