This demo illustrates how to create a drill-down chart.
The main chart is Pie, whose series points display the minimum price for each category. Clicking on any pie slice invokes the Bar chart, which displays all product prices in the selected category.
In the detail chart you can click the Back to the main view... hyperlink and the initial Pie chart will be restored. Note: the ChartControlSettings.EnableClientSideAPI must be set to true to enable this feature.
