[Gnuplot-info] Print huge data into a single plot

[Matthias_D <d00...@nt...>]

Hi,
I'm quite new to use gnuplot. Very complicated, I think. But hope I can
learn it.

My problem (I found a complicated sollution already, but maybe there is a
simple one):

There are many temperatur monitoring stations. The time of their activity
shall be plotted
as a horizontal line (x axis is the time [hours]) as well as the hours of
their malfunktion 
(set a "+" on this line).
The x axis is the time [hours] from 1 to 17544 (for 2 years).

Now I arranged the data in one file for each station. Looks like this:

First column is the time (hours), second column shows the beginning and end,
third column shows the errors.

567 1 []
678 [] 1
679 [] 1
....
17543 [] 1
17544 1 []

I inserted the brackets to tell gnuplot that here is no value to plot.
Actually the data is logical. For various stations I choose to replace the
"1" with "2", "3", .....
Then the y axis will be 1, 2, 3  and so on and the data will be plotted
horizontally for each station.
This works fine with one file. 

plot "001.txt" using 1:2 w lines,\
     "001.txt" using 1:3 w points pt1 ps1,\
     "002.txt" u 1:2 w lines,\
     "002.txt" u 1:3 w points pt1 ps1

But when I want to plot more files the output becomes miserable.

I expected to add as many files as I want, but this didn't work.

I also tried to put all the data into a single file with many columns, but
it doesn't get better.

Often comes the message "  ';' expected. "

Thanks for every hint!
