Drill-Down Java Examples

Drill-Down Through Multiple Charts

This example uses the loadParams target extensively to chart different data whenever the user selects an active label with the mouse. You can browse through the data simply by moving the mouse over a given data set and clicking the mouse button once whenever a label or outline appears. How many different charts can you find?

NOTE: The parameter files accessed by this demo are located in the classes directory in order to prevent Netscape and Internet Explorer from generating a security exception when this example is loaded via the "Open File" command. In that case, the security domain of the applets is the codebase directory itself and that is the only place from which the browsers will allow the applet to read files.

If this example is loaded from a Web server, then it doesn't matter where the parameter files are located, provided the directory is readable.

Chart Interactions

Click on any bar in the chart to drill down through the data.

Use the "Press here to go back" bar (a title) to return through the hierarchy.

Move the mouse over a bar to see the Regional sales pop-up for that period.

Move the mouse over a pink square data point to see the pop-up performance for that period.
