Graph::Template::Container::Graph - Graph::Template::Container::Graph

The root node

GRAPH

Graph::Template::Container

* 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.)

  <graph type="horiz_bars" format="jpeg" size="$graph_size">

    ... Children here ...

  </graph>

This will give you a jpeg of a chart with horizontal bars and a size set by the graph_size parameter
