Drill-down Chart

  • Demo Configurator

The example shows how the drill down functionality of the ASP.NET AJAX Chart can be used.

On the first chart the data is grouped by the greatest time span, which is year. The year is divided into quarters. By clicking on an item on the chart you can see the values corresponding to the quarters of the selected year. Each quarter consists of 3 months. After choosing a quarter for the selected year you can see the values for each month of the this quarter.
