gnuplot颜色设置及背景色设置
gnuplot作图时默认颜色7种, 命令show colorname显示预定义颜色有112种, 但去除重复后, 实际预定义的不同颜色只有97种. 在自定义设置线的颜色、更改gunuplot图的背景色时都会用到该表。

纯色系
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.
1set style line 1 lc rgb "black"
2set style line 2 lc rgb "red"
3set style line 3 lc rgb "green"
4set style line 4 lc rgb "blue"
5set style line 5 lc rgb "cyan"
6set style line 6 lc rgb "magenta"
7set style line 7 lc rgb "yellow"
8set style line 8 lc rgb "dark-yellow"
9set style line 9 lc rgb "navy"
二、更换背景色
默认背景色是白色，如这里我将默认背景色换掉，只需要设置：set terminal png x00ffff 。输出网卡的流量情况如下图：
