To Generate the chart on grid click event we use listener selectionchange event On selection change generate new store which is assign to bar chart

selectionchange: function (view, selections, options) {
                          //console.log(view, selections, options);
                          record = selections[0];
                          //var v = record.get('Field1');
                          //alert(''+v);
                          //alert(''+index)
                         // alert('hiiii')


                        record = selections[0];

                        myData=[['Domestic',record.get('field1'),record.get('field2'),record.get('field3')],
                                     ['Export',record.get('field4'),record.get('field5'),record.get('field6')],
                                     ['Other',record.get('field7'),record.get('field8'),record.get('field8'),
                                     ]]

                        }
