[Gnuplot-info] plot matrix as many graphs with different colors

[Torquil M. S. <to...@gm...>]

Hi!

I'm am plotting many graphs in one plot, by using

plot 'data.txt' matrix using ($1/M):($3) notitle with lines

where M is the number of data points in one of the directions (but that 
is not important here). The M is necessary to normalize the axis scale 
in the x-direction.

I get one graph in the plot for each line in the data file. The data 
file is simply of the form

N N N N N N
N N N N N N
N N N N N N
.
.

But I would like each graph to have a different colour. Does anyone know 
how to do this? The best thing would be if the colours are chosen 
automatically.

Best regards
