PURPOSE

The root node

NODE NAME

GRAPH

INHERITANCE

Graph::Template::Container

ATTRIBUTES

• X_WIDTH / Y_WIDTH / SIZE

  These are the width of the final graph. The defaults for both X_WIDTH and Y_WIDTH are 400. If SIZE is set, then that will be used instead of 400.

• TYPE

  This is the chart type. You can choose from the following:

  • vert_bars (default)

    Bar chart with the bars going vertically (from bottom to top)

  • horiz_bars

    Bar chart with the bars going horizontally (from left to right)

  • line_graph

    A graph with lines going from one point to another (similar to geometry class)

  • point_graph

    A graph with unconnected points

  • line_point

    A graph with points connected by lines

  • pie

    A standard pie-chart

  • mixed (Currently unsupported)

    This will allow mixed graphs, once I figure out a nice way for the template to specify it. (If you have any ideas, please let me know.)

  Most of the types can support more than one dataset in the Y axis. The only exception is 'pie'. (q.v. the POD for DATAPOINT for more details on this.)

• FORMAT

  This is the output format. You can choose from any format your current version of GD allows. The default is the return value from GD::Graph->export_format() (This will be either png or gif, depending on if your version of GD supports gif or not. Please see the GD and GD::Graph documentation for more details.)
