Chapter 25. Graphing > Creating Sophisticated Charts

Creating Sophisticated Charts

Now that you've been introduced to the basic principles involved in creating and formatting charts, we'd like to explain some of the more advanced aspects of ColdFusion MX's charting support. In the next section, you will learn how to combine several chart types into a single graph. Then you will learn how to create charts that users can click, enabling them to drill down on information presented in the graph.

Combining Multiple Chart Series

So far, all of the charts you have seen have contained only one <CFCHARTSERIES> tag. This makes sense, considering that the charts have been attempting to represent only one set of information at a time. It is also possible to create charts that represent more than one set of information, simply by adding additional <CFCHARTSERIES> tags within the <CFCHART> block. The additional <CFCHARTSERIES> tags can each display different columns from the same query, or they can display information from different queries or data sources altogether.
