NAME
GD::Graph3D - Create 3D Graphs with GD and GD::Graph

SYNOPSIS
use GD::Graph::moduleName;
my @data = (
["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"],
[ 1203, 3500, 3973, 2859, 3012, 3423, 1230]
);
my $graph = new GD::Graph::moduleName( 400, 300 );
$graph->set(
x_label => 'Day of the week',
y_label => 'Number of hits',
title => 'Daily Summary of Web Site',
);
my $gd = $graph->plot( \@data );

Where moduleName is one of "bars3d", "lines3d" or "pie3d".

DESCRIPTION
This is the GD::Graph3d extensions module. It provides 3D graphs for the GD::Graph module
by Martien Verbruggen, which in turn generates graph using Lincoln Stein's GD.pm.

You use these modules just as you would any of the GD::Graph modules, except that they
generate 3d-looking graphs. Each graph type is described below with only the options that
are unique to the 3d version. The modules are based on their 2d versions (e.g.
GD::Graph::bars3d works like GD::Graph::bars), and support all the options in those. Make
sure to read the documentation on GD::Graph.

GD::Graph::pie3d
This is merely a wrapper around GD::Graph::pie for consistency. It also sets 3d pie
mode by default (which GD::Graph does as of version 1.22). All options are exactly as
in GD::Graph::pie.

GD::Graph::bars3d
This works like GD::Graph::bars, but draws 3d bars. The following settings are new or
changed in GD::Graph::bars3d.

bar_depth
Sets the z-direction depth of the bars. This defaults to 10. If you have a large
number of bars or a small chart width, you may want to change this. A visually
good value for this is approximately width_of_chart / number_of_bars.

overwrite
In GD::Graph::bars, multiple series of bars are normally drawn side-by-side. You
can set overwrite to 1 to tell it to draw each series behind the previous one. By
setting overwrite to 2 you can have them drawn on top of each other, that is the
series are stacked.

shading
By default this is set to '1' and will shade and highlight the bars (and axes).
The light source is at top-left-center which scan well for most computer users.
You can disable the shading of bars and axes by specifying a false value for this
option.

GD::Graph::lines3d
This works like GD::Graph::lines, but draws 3d line. The following settings are new or
changed in GD::Graph::line3d.

line_depth
Sets the z-direction depth of the lines. This defaults to 10. If you have a large
number of bars or a small chart width, you may want to change this. A visually
good value for this is approximately width_of_chart / number_of_bars.

shading
By default this is set to '1' and will shade and highlight the line (and axes).
The light source is at top-left-center which scan well for most computer users.
You can disable the shading of lines and axes by specifiying a false value for
this option.

VERSION
0.63 (6 December 2002)

INSTALLATION
You will need to have the GD::Graph version 1.30 or later installed. You should also have
Perl version 5.005 or 5.6 installed.

To install, just do the normal:

perl Makefile.PL
make
make install

The documentation is in GD::Graph::Graph3d.pod.
