- =head1 NAME
-
- GD::Graph3D - Create 3D Graphs with GD and GD::Graph
-
- =head1 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 I<moduleName> is one of C<bars3d>, C<lines3d> or C<pie3d>.
-
- =head1 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.

-
- =item 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.
-
- =item GD::Graph::bars3d
-
- This works like GD::Graph::bars, but draws 3d bars. The following settings
- are new or changed in GD::Graph::bars3d.
-
- =over 4
-
- =item 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.
-
- =item 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.
-
- =item 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.
-

-
- =item GD::Graph::lines3d
-
- This works like GD::Graph::lines, but draws 3d line. The following settings
- are new or changed in GD::Graph::line3d.
-
- =over 4
-
- =item 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.
-
- =item 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.
