Drill-Down/Zooming Column Chart Servlet Example
Value of Portfolio

This example shows a Column Chart based on the value of a portfolio for a hypothetical client.  The graph is shown with dollar value versus month of the year.  The example shows the time-based zooming ability of EspressChart.  Furthermore, it also shows the ability of EspressChart to create hyper-links to specified Web locations.

The initial graph is from January to July.  You are able to select a different month range.  Click on a particular month to get all the days in that month.  Then, select the particular days that would be of interest.  Note that the hyperlinks, when the individual day datapoints are clicked, would take you to the specific data for that day.
