..Well, not quite. Microsoft have not actually bought Dundas but they have bought the code base for the charting, gauge, calendar, map and barcode controls. This is excellent news - I've used Dundas charting in various guises for a number of years and have been well impressed with the depth and breadth of the suite.
The plan is to integrate the charting functionality into Reporting Services 2008 (Katmai). Adding this functionality to Reporting Services is going to be great step forward and I can't wait to start developing some presentation ready reports. Should make the sales pitch easier too !
