gnuplot:在键中同时显示中心线和误差带 [英] gnuplot: showing both center line and error band in a key

问题描述

我想通过使用以下命令来绘制一个带有错误带的数据集，它为每个数据集创建单独的键(一个键用于频段，一个键用于中心线)，但我希望这些键彼此显示在一个键中

I want to plot a data set with it's error band by using the following commands, it creates separate keys for each of them (one for band and one for central line) but I want these keys shown in one key on each other.
