Hi Asmita,
We kindly recommend you to concentrate on Syncfusion.Chart.WPF control instead Syncfusion.OlapChart.WPF control since OLAP Chart has been explicitly designed only to visualize OLAP data not ordinary flat/relational Data.
Please find the samples and details for Chart WPF in the below link.
Installtion Sample Location: <system drive>\Users\<user name>\AppData\Local\Syncfusion\EssentialStudio\<version number>\WPF\Chart.WPF\Samples\
Online Documentation: http://help.syncfusion.com/ug/wpf/default.htm#!documents/overview15.htm
Let us know if you need any further assistance.
Regards,
Jesus Arockia Sankaran S
