嗨，伙计们，我想知道是否可以传递隐藏的输入值以在 Google 图表中提供数据，我有一些单选按钮旨在更改要存储在隐藏输入中的数据，我已经检查了这个和我的代码以进行更改数据似乎有效，但图表没有重绘。我怎样才能触发类似重绘功能的东西。谢谢。
google.setOnLoadCallback(drawChart);
function drawChart() {
var sample_data = document.getElementById('sample_data').value;
var data2 = eval("["+sample_data+"]");
var data = new google.visualization.arrayToDataTable(data2);
var options = {
hAxis: {title: 'Age', minValue: 0,maxValue:105},
vAxis: {title:'Savings', minValue: 0,maxValue:2500000},
width: 960, height: 300,
colors: ['#4a82bd'],
legend:'none'
};
var chart = new google.visualization.AreaChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
drawChart();
function ViewModel() {
var self =this;
self.rangeSelect = ko.observable('0%');
self.dataGetter = ko.computed(function(){
var range = self.rangeSelect();
