无法在我的Google图表中使用NumberRangeFilter

Question

我试图弄清楚为什么我的范围滤镜在我的图表中没有显示或没有显示。我试图查看Google Charts doc，但出于某种原因，我不确定我是否以正确的方式执行此操作。我想要的是你可以通过类别过滤器来解决数据。但我也希望过滤范围（滑块）以查看当年的具体数据。

这里是fiddle

HTML

<div id="rangeFilter_div"></div>
<div id="colFilter_div"></div>
<div id="chart_div"></div>

的JavaScript

google.load('visualization', '1', {packages: ['controls']});
google.setOnLoadCallback(drawChart);

function drawChart () {

    data.addColumn('number', 'Foo');
    data.addColumn('number', 'Bar');
    data.addColumn('number', 'Baz');
    data.addColumn('number', 'Cad');
    data.addRows([
        ['2005',  45, 60, 89, 100],
        ['2006',  155, 50, 79, 24],

    for (var i = 1; i < data.getNumberOfColumns(); i++) {
        columnsTable.addRow([i, data.getColumnLabel(i)]);
        // you can comment out this next line if you want to have a default selection other than the whole list
        initState.selectedValues.push(data.getColumnLabel(i));
    }
    // you can set individual columns to be the default columns (instead of populating via the loop above) like this:
