25 This is the GD::Graph3d extensions module. It provides 3D graphs for
26 the GD::Graph module by Martien Verbruggen, which in turn generates
27 graph using Lincoln Stein's GD.pm.
28 You use these modules just as you would any of the GD::Graph modules,
30 except that they generate 3d-looking graphs. Each graph type is
31 described below with only the options that are unique to the 3d ver‐
32 sion. The modules are based on their 2d versions (e.g.
33 GD::Graph::bars3d works like GD::Graph::bars), and support all the
34 options in those. Make sure to read the documentation on GD::Graph.
35 GD::Graph::pie3d
37 This is merely a wrapper around GD::Graph::pie for consistency. It
38 also sets 3d pie mode by default (which GD::Graph does as of ver‐
39 sion 1.22). All options are exactly as in GD::Graph::pie.
40 GD::Graph::bars3d
42 This works like GD::Graph::bars, but draws 3d bars. The following
43 settings are new or changed in GD::Graph::bars3d.
44 bar_depth
46 Sets the z-direction depth of the bars. This defaults to 10. If
47 you have a large number of bars or a small chart width, you may
48 want to change this. A visually good value for this is approx‐
49 imately width_of_chart / number_of_bars.
50 overwrite
52 In GD::Graph::bars, multiple series of bars are normally drawn
53 side-by-side. You can set overwrite to 1 to tell it to draw
54 each series behind the previous one. By setting overwrite to 2
55 you can have them drawn on top of each other, that is the
56 series are stacked.
57 shading
59 By default this is set to '1' and will shade and highlight the
60 bars (and axes). The light source is at top-left-center which
61 scan well for most computer users. You can disable the shading
62 of bars and axes by specifying a false value for this option.
63 GD::Graph::lines3d
65 This works like GD::Graph::lines, but draws 3d line. The following
66 settings are new or changed in GD::Graph::line3d.
67 line_depth
69 Sets the z-direction depth of the lines. This defaults to 10.
70 If you have a large number of bars or a small chart width, you
71 may want to change this. A visually good value for this is
72 approximately width_of_chart / number_of_bars.
73 shading
75 By default this is set to '1' and will shade and highlight the
76 line (and axes). The light source is at top-left-center which
77 scan well for most computer users. You can disable the shading
78 of lines and axes by specifiying a false value for this option.
