From: Satyarth Negi Date: Wed Jun 15 05:41:44 2005 Subject: DBDGraph Plotter Help Needed !!!
I running the following script .
------------------------------------------------------------------------
#!/usr/bin/perl
use lib '/home/satyarth/GD_LIB';
use GD;
use DBD::Chart ;
use DBD::Chart::Plot;
my $img = DBD::Chart::Plot->new();
my @xdataset = (1,2,3,4,5,6);
my @ydataset = (3.2,1.1,5.5,6.2,0,7.9);
$img->setPoints(\@xdataset, \@ydataset,'blue line');
$img->setOptions (
horizMargin => 75,
vertMargin => 100,
title => 'My Graph Title',
xAxisLabel => 'my X label',
yAxisLabel => 'my Y label' );
open(FILE,'>output.gif');
binmode FILE;
print FILE $img->plot;
close(FILE);
---------------------------------------------------------------
When i run the script , file output.gif is created in the directory
but it is empty , doesnt contain anything .
Can you tell me why is this happening ? Where did i go wrong ?
Also Im using DBD because i want to draw multiple plots on a single
graph . Is there any better way i can do it ?
Thanks in anticipation .
