Is there a easy way to get points with black outline in gnuplot?

Question

Is there a easy way to get points with black outline in gnuplot? I\'m using standard color filled point types, for example:

set style line 3  lc rgb \'#4682B         


        

Answer 1

The simplest "quick and dirty" solution that comes to mind is to plot the data set twice, once with the full symbol style and then with an empty symbol style. For instance:

plot "temp" pt 9 ps 2, "temp" pt 8 ps 2 lc 0 lw 2
