Macromedia® ColdFusion® MX Evaluator's Guide Enhanced Charting ColdFusion 5 introduced the ColdFusion charting engine, an embedded service for producing professional graphs and business charts from application data. ColdFusion MX takes this feature to the next level by expanding the number and complexity of supported charts, increasing the available formatting options, and enabling offline chart generation. This release also introduces a more flexible syntax for creating charts from application data. In addition to bar charts, pie charts, and line graphs, ColdFusion MX now supports eight additional chart types, including the ability to mix different types in the same chart (e.g., bar chart with overlaid line graph). Other new features include support for multiple data series within a single chart as well as expanded functionality for enabling data drill-downs.

This is particularly useful for reports that do not need to access real-time data or for high-volume applications. Frequently requested charts can be cached on disk and refreshed every minute, hour, etc. This not only improves response time but also reduces the load each request places on the server. 31
