使用gnuplot绘制具有多行的CSV文件 [英] Plot csv file with multiple rows using gnuplot

问题描述

我有一个csv文件，其中包含500行和100列.

I have a csv file which contains 500 rows and 100 columns.

我想按以下方式绘制数据:

I want to plot the data in the way that:

1. 每一行代表图形上的一条曲线.每列代表一个曲线上的值(100个值).
2. 在图形上有500条这样的曲线.

代码:

set xrange [0:100]
set yrange [0:20]
set term png
set output 'output.png'
set datafile separator ','
plot 'myplot.csv'

但这似乎不起作用.我该如何配置gnuplot来实现这一目标?

But this does not seem to work. How can I configue gnuplot to achieve that?

数据采用以下格式(变短):

The data is in this format (Shortened):

推荐答案

set datafile separator comma
plot for [row=0:*] 'myplot.csv' matrix every :::row::row with lines

但是我怀疑有500条线会导致情节过于拥挤而无法解释.

However I suspect that with 500 lines the plot will be too crowded to interpret.
