thank you

you hiding element using class selector, hide elements class present, should identify node other selector

if need hide node , have updated data itself, here how can go it.

var runonce = google.visualization.events.addlistener(chart, 'ready', function() {     // set + sign event handlers     var previous;     $('#chart_div').on('click', 'div.plus', function () {         var selection = chart.getselection();         var row;         if (selection.length == 0) {             row = previous;         }         else {             row = selection[0].row;             previous = row;         }         var collapsed = chart.getcollapsednodes();         var collapse = (collapsed.indexof(row) == -1);          chart.collapse(row, collapse);         chart.setselection();          // new list of collapsed nodes         collapsed = chart.getcollapsednodes();          // set event listener recollapse nodes after redraw         var runonce2 = google.visualization.events.addlistener(chart, 'ready', function() {             google.visualization.events.removelistener(runonce2);             (var = 0; < collapsed.length; i++) {                 chart.collapse(collapsed[i], true);             }          });        var children =chart.getchildrenindexes(row);       for(var i=0;i< children.length;i++)       {           var childrenofchildren =     chart.getchildrenindexes(children[i]);           if(childrenofchildren == "")           {            var col1 = data.getvalue(children[i],0);            var col2 = data.getvalue(children[i],1);            var col3 = data.getvalue(children[i],2);             data.removerow(children[i]);            data.insertrows(children[i], [[col1, col2, col3]]);            }       }          // redraw chart account change in sign         chart.draw(data, options);      });
