默认的7种颜色有时候不够用, 可以利用lc rgb进行自定义, 更方便的是利用set style line命令. 下面定义了与Origin默认一致的颜色.

# Language: bash
set style line 1 lc rgb "black"
set style line 2 lc rgb "red"
set style line 3 lc rgb "green"
set style line 4 lc rgb "blue"
set style line 5 lc rgb "cyan"
set style line 6 lc rgb "magenta"
set style line 7 lc rgb "yellow"
set style line 8 lc rgb "dark-yellow"
set style line 9 lc rgb "navy"
