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

I want to plot the data in the way that:

  1. Each row represent a curve on the graph. Every column represents a value on the curve (100 values).
  2. 500 such curves on the graph.

The code:

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

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

Edit:

The data is in this format (Shortened):

  • Could you give us the error or something? It's impossible to help troubleshoot without any diagnostic data. Commented Jun 25, 2018 at 20:45
  • There is no error. I got an empty output file. Commented Jun 25, 2018 at 21:14
  • maybe stackoverflow.com/questions/8646446/… can help Commented Jun 26, 2018 at 4:46
  • Can you easily invert the data so each row has a value on the curve and each column is a curve? Commented Jun 26, 2018 at 20:24

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

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