绘图点大小不变

Plot point size not changing

this answer 中所述,ps 设置可用于更改绘图的点大小:

plot "./points.dat" using 1:2 pt 7 ps 10     # small point size
plot "./points.dat" using 1:2 pt 7 ps 100    # large point size

然而 ps 在使用字符点类型时似乎被忽略了:

plot "./points.dat" using 1:2 pt "X" ps 10     # small point size
plot "./points.dat" using 1:2 pt "X" ps 100    # small point size

如何更改 "X" 等字符点类型的点大小?

试试这个:

plot '+' u 1:1 w p pt "X" font ",10"
plot '+' u 1:1 w p pt "X" font ",100"
