Hi Vinod, 

We have analyzed your query. We can achieve your requirement using pointRegionClick event, in this, we can get the current point index. Based on the point index we have rendered the information with new data.  

Please find the below code  snippet to achieve this requirement, 

$("#container").ejChart( 
            { 
               commonSeriesOptions: 
                { 
                    type: 'stackingbar', 
                }, 
                series: 
                [ 
                    { 
                        points: [{ x: "SUV", y: 25, text: '25%' },  
                            . . . 
                            . . . other points 
                        ], 
                    },      
                   { 
                        points: [{ x: "SUV", y: 20, text: '20%' }, 
                            . . . 
                            . . . other points 
                        ], 
                    } 

                ], 
                . . .  
                . . . other customization 
                pointRegionClick: 'onclick', 
            }); 

function onclick(sender) { 
       var pointIndex = sender.data.region.Region.PointIndex; 
       var seriesIndex =sender.data.region.SeriesIndex; 
       document.getElementById("text").innerHTML=sender.model._visibleSeries[0]._visiblePoints[pointIndex].x; 
          $("#container").ejChart("option", { "drilldown": barSeries(pointIndex, seriesIndex) }); // here drill down the clicked point index 
       document.getElementById("symbol").style.visibility = "visible"; 
   } 

function barSeries(index, seriesIndex) { 
if (seriesIndex == 0) { 
  if (index == 0) { 
  return { 
          series: 
            [ 
            { 
            points: [{ x: "Toyota", y: 8, text: 'Toyota 8%' }, 
                                           . . . 
                                           . . . other points 
                                           ], 
                                           . . . 
                                           . . . other customization 
            } 
           ], 
     }; 
  } else { 
  . . .  
  . . . as like the index 0 customize the other indexes  
  } 
} else if(seriesIndex == 1){ 

} else { 
// give the initial series collections. This is for when click the  back from the drilled series. 
} 
}
