$("#PivotGrid1").ejPivotGrid({
 dataSource: {
  data: "http://localhost/OLAP/msmdpump.dll",
  catalog: "Adventure Works DW Tabular",
  cube: "Internet Sales",
  rows: [{
         fieldName: "[Date].[Fiscal]"

});
 

@Html.EJ().Pivot().PivotGrid("PivotGrid1").DataSource(dataSource => dataSource.Rows(rows=>{rows.FieldName("[Date].[Fiscal]").Add();}).Columns(columns=>{columns.FieldName("[Customer].[First Name]").Add();}).Values(values => { values.Measures(measures => { measures.FieldName("[Measures].[Internet Total Sales]").Add(); }).Axis(AxisName.Column).Add();}).Data("https://bi.syncfusion.com/olap/msmdpump.dll").Catalog("Adventure Works DW Tabular").Cube("Internet Sales"))
