@yansonalvin97,
Incase of multiseries chart, there will be only one chart-container and multiple dataSeries. Whereas if you like to have 3 different pie charts there should be 3 different chart-containers. You can achieve this by creating 3 separate chart-containers and 3 different charts using the existing chart-options and updating it back again when other chart-type is selected. Please take a look at this jsfiddle.
