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.
