[Gnuplot-info] Several horizontal lines

[Daniel C. <dcl...@ya...>]

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

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

Thanks, this exactly parses the file. It will also be a good exercise to understand that.

  I supposed there would be a simpler way to do this in gnuplot. It is a common graph.

simpler ways - 'outside' gnuplot, maybe, but 'inside', i don't think so,
because you read y-values in, which are then to be used as constant
functions after reading them in, that's somehow a 'misuse' of gnuplots
plotting mechanism.

'outside' gnuplot, e.g.:

load "< awk --field-separator \",\" 'BEGIN {temp = sprintf(\"plot\")} {if
(NR>1) temp = temp \",\" ; temp = temp $2 \" title \" \"\\\"\" $1 \"\\\"\"}
END{print temp}' ts.dat"
