Chapter 24. Graphing and Charting
ColdFusion 5.0 provides you with a new way of looking at data,
literally, in the form of a server-side graphing engine comprised of
Macromedia’s JRun and Generator servers.[22] These servers, combined
with the new CFGRAPH and
CFGRAPHDATA tags allow you to add new charting and
graphing capabilities to your ColdFusion applications.
Five types of graphs and charts are supported with this release of
ColdFusion. They are bar and horizontal bar charts, line and area
graphs, and pie charts. The CFGRAPH tag can
generate graphs in Macromedia’s popular Flash format, as PNG
images or as JPEG images. You can use the CFGRAPH
and CFGRAPHDATA tags to graph static values, query
data, or a combination of the two.
Creating a Simple Graph
Regardless of the type of graph you want to
create, all graphing is handled via the CFGRAPH
tag. The CFGRAPH tag is a paired tag, meaning it
must always have opening and closing tags. To create a graph of any
type from static data, you need to include one or more
CFGRAPHDATA tags between your beginning and ending
CFGRAPH tags. Example 24-1 shows
how to generate a bar chart from static data.
