Hi Harish NC,
I believe this help topic
will help you with this task -- it describes how to group the chart items into series based on a value in a certain column/property. Unfortunately, the hierarchical labels for the vertical axis are not directly supported in RadChart. In case the higher level labels (Novartis and KOL) are static or there is a limited number of them you can create a custom image, which holds them and use it as RadChart background.
