you need gnuplot 4.3-cvs
set datafile separator ","
t=""
plot for [i=0:4] 'ts.dat' us ((i==0&&$0==0)?(b=$2,t=stringcolumn(1)):99 , $0==0?(a=b):99, $0==(i+1)?(b=$2,t=stringcolumn(1)):99 , $0):(a) with lines title t

Hi, I look for orientation on how to plot a graph I have seen no examples for.
Imagine you have this data consisting of tower_name+tower_height:
Burj Dubai, 818
KVLY-TV mast, 628.8
CN Tower, 553.3
Sears Tower, 527.3
Taipei 101, 509.2
I want a graph with 5 horizontal lines, each at the height specified by the second parameter.
Similar in nature to this graph:
https://eshu.ubuntu-eu.org/cgi-bin/munin-cgi-graph/ubuntu-eu.org/eshu/smart_sdb-month.png I could do manually: plot 818 title "Burj Dubai", 628.8 title "KVLY-TV mast", 553.3 title "CN tower", 527.3 title "Sears Tower", 509.2 title "Taipei 101"
But I want the data to be read from a file.
Can this be done with a gnuplot command?
Thanks,
Daniel
