Hi vikas,
You may download ChartDirector for C++. It contains a lot of QT sample code. In particular, the sample code qtdemo contains over 100 sample charts, including the polar scatter chart. The Installation section of the documentation included in the download includes steps on how to run the sample code, and also how to use ChartDirector in QT in your own projects in various operating systems.
Hope this can help.
Regards
