如何根据所选日期更改甘特图数据

为了在选择日期时更改图表，您必须将eventlistener添加到<input type="date" name="report" tooltip="Day"></div>。我已经更改了您的代码并更新了代码。

var app = angular.module('myApp', ["ng-fusioncharts"]),
	globalContainer = {},
	_intUpdate;
app.controller('ReportsController', ['$scope', function ($scope) {
    $scope.chartOptions = [{
        id: 1,
        name: "Day 1"
    }, {
        id: 2,
        name: "Day 2"
    }];
    $scope.reportsDataSource = {
        "chart": {
