[Gnuplot-info] traffic plotting

[Wolf D. <dre...@ve...>]

Hello,

months ago I issued a request to visualize the traffic of a small bus  
network. At that time that was preparation for a project ahead, which  
now has to be worked upon.

The task is this:

I have a list, each line contains a pair of bus stops, represented by  
cartesian coordinates and a number of passengers travelling between  
these two stops. Thomas was so kind to propose a solution for this  
issue, unluckily I could not make it work up to now. The suggestion  
was the following:

set terminal aqua font "Times,5"
number_of_busstops = 271
plot "FGZ.xls" using 2:(my_lw=$1, 0/0) every 1::0::0 notitle, for  
[i=1:number_of_busstops] "" using 2:(my_lw=$1, $3) every 1::(i-1)::i  
with lines linetype 1 linewidth my_lw notitle

Using gnuplot 4.2.5 on a Mac I get this result:

gnuplot> set terminal aqua font "Times,5"
Terminal type set to 'aqua'
Options are '0 title "Figure 0" size 846 594 font "Times,5"  
noenhanced solid'
gnuplot> number_of_busstops = 271
gnuplot> plot "FGZ.xls" using 2:(my_lw=$1, 0/0) every 1::0::0  
notitle, for [i=1:number_of_busstops] "" using 2:(my_lw=$1, $3) every  
1::(i-1)::i with lines linetype 1 linewidth my_lw notitle
                                       ^
          ')' expected


The "^" points exactly at that place:

plot "FGZ.xls" using 2:(my_lw=^

I'd be grateful for any support to make this little script work.

Greetings,

Wolf
