Gnuplot also lets you plot more than one graph so that they appear side-by-side on the same output screen or file.
Gnuplot使您还可以绘制多个图，这样它们可以并排显示在同一输出屏幕或文件中。
First, the data input file name is given, then we inform gnuplot what columns to plot.
首先，指定数据输入文件名，然后告诉gnuplot要绘制哪些列。
A line plot can be saved as a JPEG image, a report can be saved as HTML, and raw data can be saved as a CSV file.
线图可以另存为jpeg图像，报告可以另存为HTML，原始数据可以另存为CSV文件。
For complete flexibility, in Unix-like systems with a popen function, you can pre-process the file with text processing utilities before it is passed into the plot command.
为了获得更完全的灵活性，在具有popen函数的unix类系统中，在将文件传送给plot命令之前，可以使用文本处理实用程序对文件进行预处理。
