Thank you
tospo.
The problem is that not each number can be combined with each evaluation name. Therefore I do need a config file. In fact I happened to populate the hash %module reading the csv-file in the following way:
open(my $fh, "<", "parameter.csv") or die "$!";
my $header = <$fh>;
while(<$fh>) {
my @line = split(/;/, $_);
my $t = $line[0];
${module}{$t}{name} = $line[1];
my $n = $line[2];
${module}{$t}{indicator}{$n}{ind} = $line[3];
${module}{$t}{indicator}{$n}{yscala} = $line[4];
}
close $fh;
The file names in the gnuplot command are generated afterwards on the fly whereby only the names are created which are allowed by config file.
After that I used the code from
wfsp from
Re^2: How to declare variables per loop in the following way:
my @cmds;
for my $number (sort keys %{${module}{$topic}{indicator}}){
my $cmd = build_command($number, %args);
push @cmds, $cmd;
}
for (my $i=0; $i<@cmds; $i++) {
if($i == 0 or $i % 2 == 0) {
$cmds[$i] = "$multiplot\n\n$cmds[$i]";
}
}
for (my $i=0; $i<@cmds; $i++) {
if($i % 2 == 1 or $i == $#cmds) {
$cmds[$i] = "$cmds[$i]\n\n unset multiplot\n\n";
}
}
my $slurpline;
for (my $i=0; $i<@cmds; $i++) {
$slurpline.=$cmds[$i];
}
The gnuplot command itself is very short now:
open my $P, "|-", "gnuplot" or die;
printflush $P qq[
$postscript
$slurpline
];
close $P;
Thanks again!

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
