Hi All,

I am trying to create a barchart to display progress of various open projects. Progress data is stored in database.

I am able to extract data from database and plot the graph but if i try to set legends through a variable, my script fails. Here is the code:- 


$sql="SELECT pno,pname FROM t1 WHERE status=? AND ctry=?";
my $sth = $dbh->prepare($sql);
$sth->execute('O','GB');
while(my $row=$sth->fetchrow_hashref){
  push @projects,$row;
}

##Now get progress data from table
$sql="SELECT NVL(progress,0) FROM chart WHERE pno=? AND chartyear = 20
+05 AND chartmonth in(6,7,8) ORDER BY chartmonth";
foreach (@projects){
  $pno= $_->{'PROJECTNUMBER'};
  @dat=getMultiRows($sql,1,$dbh,$pno);
  push(@data,\@dat);
  $projectname .= "'".$_->{'PROJECTNAME'}."'".",";
}
chop $projectname;

##Now plot the graph

my $mygraph = GD::Graph::bars->new(500, 300); 
$mygraph->set(
    x_label     => 'Months',
    y_label     => '% Completed',
    title       => 'Project Log progress',
    bar_width   => 2,
    bar_spacing     => 2,
    long_ticks      => 1,
    show_values     => 1,
    x_label_position => 0.5,
    t_margin         => 10,
    b_margin         => 10,
    l_margin         => 10,
    r_margin         => 10,
) or warn $mygraph->error;
 
$mygraph->set_legend_font(GD::gdMediumBoldFont);


$mygraph->set_legend('Dynamic reconfiguration FY06 Initiative','Rmg Es
+calation Management Tool'); # Works fine

##Above works but when I try following it fails though value of $proje
+ctname is same as above value supplied to set_legend function.

#$mygraph->set_legend($projectname); #This fails

my $myimage = $mygraph->plot(\@data) or die $mygraph->error;
 
print "Content-type: image/png\n\n";
print $myimage->png;
