如何在gnuplot中绘制缺少数据点的线 [英] How to plot line with missing data points in gnuplot

问题描述

示例:

我想像上图一样绘制一个图表:一条线缺少一些数据点，这意味着该线是不连续的.

I want to plot a chart just like above one: a line with some missing data points, that means the line is discontinuous.

我该怎么做?

推荐答案

这取决于您的数据文件的外观.如果在数据文件中插入空格，它将不会连接那些相邻的点(这是最简单的方法):

This depends on what your datafile looks like. If you insert a blank space in your datafile, it won't connect those adjacent points (This is the easiest way):

考虑:

 #datafile
 1 2
 2 3

 4 2
 5 3

，然后是绘制它的脚本:

and then the script to plot it:

 plot 'datafile' u 1:2 w linespoints

您还可以使用其他技巧来处理丢失的数据:set datafile missing.内置帮助(help missing)是一个很好的参考.

There are other tricks you can play with missing data: set datafile missing. A good reference for this is the builtin help (help missing).
