通过谷歌图表中列显示的总和

Question

<script>
   $("input.JKLL").each(function(i) { // select all column total elements
        this.value = columnTotals[i];
        var ChartData = this.value;
    }
    google.charts.load('current', {
        'packages': ['bar']
    }); google.charts.setOnLoadCallback(drawChart);
    function drawChart(ChartData) {
        //var datas = null;
        var chartData = ChartData;
        var data = google.visualization.arrayToDataTable(chartData)
        var options = {
            bars: 'vertical' // Required for Material Bar Charts.
        };
        var chart = new
        google.charts.Bar(document.getElementById('chart_div'));
        chart.draw(data,
            google.charts.Bar.convertOptions(options));
    });
</script>
<div id="chart_div" style="width: 1150px; height: 300px"></div>

我想在Google图表中的ChartData中显示我的数据。我在ChartData中有一个7值，我在Google图表数据中声明了这些数据，但是它没有用。
