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 ^

0.56 (August 9, 2001)

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.
