Re: [Gnuplot-info] using different line styles for multiple plots - from one data file

[doug b. <dou...@ho...>]

Hi,

Thank you for suggesting the use of index.

However, I have many data set and writting them all out using index is 
painful.

So, here is what I would like to do: I have many data sets in a file. The 
data sets are separated by two blank lines. I would like to plot all the 
data sets on one plot and have each one have its own "key"

I have come up with a solution, but it is not to neat. My problem is that it 
appears that the "key" does not allow one to write out a variable as you can 
do with label. Is this true?

To get around this I have made the following do loop to loop over the data 
sets and
to have a key for each data set and label it. Is there a better way to do 
this.

set multiplot
n=0; n2=10
load 'cmd'

Where the file 'cmd is:
r=(n+1)/12
set label "%g",n at screen .6,r
set key screen .9,r
plot 'junkresidl' index n:n u 3:4 w l lt (n+1)
pause 0
n=n+1
if(n<n2) reread

Thank you,
