用线gnuplot绘制矩阵 [英] plot matrix with lines gnuplot

问题描述

我正在制作图表，但我想使用线而不是点.

I'm making a chart but I would like to use lines rather than points.

使用线条样式，所有点均已连接，并且图形具有网络外观，这是我所不希望的.

Using the style of lines, all the points are connected and the graph has a network appearance, which I don't want.

set grid 
set ticslevel 0.1 
set samples 51, 51 
set isosamples 20, 20 
set border 1+2+4+8
unset key
splot 'matrix.dat' matrix

推荐答案

这不能自动完成.您必须确定矩阵的行和列.首先，要获取行数，请使用

This cannot be done automatically. You must determine the rows and columns of your matrix. First, to get the number of rows, use

stats 'matrix.dat' using 1 nooutput
rows = STATS_records

有关列数，请使用

stats 'matrix.dat' matrix nooutput
cols = STATS_records/rows

现在绘制每一行

unset key
splot for [i=0:cols-1] 'matrix.dat' matrix every ::i::i lt 1 with lines

结果(含4.6.4)为:

Result (with 4.6.4) is:
