Different colours to different bars (perl graph)

[JackTheRussel]

Hi,

I have program which draw picture where are min, max and avg bars.

I have tried everything, but I can't set different colours to different bars.

Here is the program

#!/usr/bin/perl

use GD::Graph::bars3d; 
my $graph = new GD::Graph::bars3d( 400, 300 );

my @data = (
	    ["Min", "Max", "Avg"],
	    [ 2,  10,  5]
	    );

$graph->set(
	    x_label           => 'x_label title',
	    y_label           => 'y_label title',
	    title             => 'Head title',
	    dclrs             =>  [ qw(gold blue green) ],
	    );

my $gd = $graph->plot( \@data );
open(IMG, '>picture.png') or die $!;
binmode IMG;
print IMG $gd->png;

Here I try to set different colours to different bars

dclrs             =>  [ qw(gold blue green) ],

But it set all bars to gold-color.

And if I change order like this:

dclrs             =>  [ qw(blue gold green) ],

It set all bars to blue.

So what I have to do that I can set all tree bars into different colours ?

change the color, plot the next line, instead of doing it all in the one plot

Did you mean something like this?

my @data1 = (["min"],[2]);
my @data2 = (["max"],[8]);
my @data3 = (["avg"],[4]);

$graph->set( dclrs => [ qw(red) ] ); 
   my $gd = $graph->plot( \@data1 )

$graph->set( dclrs => [ qw(blue) ] ); 
   my $gd = $graph->plot( \@data2 )

$graph->set( dclrs => [ qw(yellow) ] ); 
   my $gd = $graph->plot( \@data3 )

If I do like this, then I get three bars which are
one after the other and it's not looking good ?

where did you see this?

dclrs => [ qw(gold blue green) ],

the GD::Graph module makes no mention of such a setting.

$graph->set( dclrs => [ qw(green pink blue cyan) ] );

I look at example which was here:

OK, I see it now.

Just below that it says:

The first (fifth, ninth) data set will be green, the next pink, etc.

do you understand what that means? I don't because the documentation is quite long so I didn't read through it to try and find out.
