The Healthcare Effectiveness Data and Information Set (HEDIS) is a tool used to measure and quantify
performance on important dimensions of care and service.
The set of standardized measures is developed and maintained
by the National Committee for Quality Assurance.
This page uses the Microsoft Chart Control for ASP.NET. Chart data is obtained from a SQL Server database (using Linq to SQL)
and is dynamically fed to the control. The chart type is a range bar chart, and we added strip lines showing national averages.
The Microsoft Chart control is based on Dundas Chart source code version 5.5. Microsoft acquired the rights for the technology in 2007
and integrated parts in SQL Server 2008 Reporting Services. The chart control for .Net 3.5 is a separate download, but will probably be
fully integrated in one of the upcoming releases.
Charts can be made interactive, since many elements support post-backs. The zoom feature with the Ajax slider on this page does
not do justice to the possibilities.
