Thanks @justinedwards.jle
Actually i want to know about how to create the relationship between those datasets to series field and i was stuck in that point could you help me in this part?

Are wanting to add another dataset to an existing dataset in your data property, or are you looking to bind the data property to a data source in order to produce a dataset?

No Just added a dataset to the example datasource and configured the series fields as follow

Have a great Day!
