17. Graphing and Charting > 17.5. Drilling Down on Graph Data

Drilling Down on Graph Data

Another useful feature of the cfchart tag is the ability to create graphs with clickable data points that can link to other templates. This allows you to implement drill-down functionality as we did in Chapter 11, using a graph instead of an HTML table. In order to create a clickable graph, you have to set format to Flash. Examples 17-6 and 17-7 demonstrate how to create a pie chart with drill-down capabilities. The pie chart displays the total amount of incentive award dollars given out per department, and it allows you to click on any pie slice and have it drill down to that specific department’s data.
