Google图表（可视化）中堆积条形图中的第三个条形图无效

Question

我使用谷歌图表（谷歌可视化），它工作正常。但现在，我在动画中遇到了一个奇怪的问题。这是一个堆积的条形图。前两列（条形）完美无瑕地动画，但第三列（条形）立即出现，动画不适用于最后一个条形（第三列）。

我试过总共2个酒吧，现在第二个酒吧的动画不起作用（马上就来了）。很明显，问题在最后一栏。这是Google Chart最终的堆积条形图中的缺陷吗？

这是我的代码：

            var data = google.visualization.arrayToDataTable([
            ['Status', awating, not_interested, interested, { role: 'annotation' }],
            ['SANDRA COOMBS', 2, 4, 2, ''],
            ['VINCENT ODA', 2, 2, 2, ''],
        ]);
        arTotal = niTotal = iTotal = 0;
        for (var i = 0; i < data.getNumberOfRows(); i++) {
            if (data.getValue(i, 1) != null) {
                arTotal += data.getValue(i, 1);
            }
            if (data.getValue(i, 2) != null) {
                niTotal += data.getValue(i, 2);
            }
            if (data.getValue(i, 3) != null) {
                iTotal += data.getValue(i, 3);
            }
        }
        var view = new google.visualization.DataView(data);
        view.setColumns([0, 1,
            {
                calc: "stringify",
                sourceColumn: 1,
                type: "string",
                role: "annotation"
            },
            2, {
                calc: "stringify",
                sourceColumn: 2,
                type: "string",
                role: "annotation"
            },
            3, {
                calc: "stringify",
                sourceColumn: 3,
                type: "string",
                role: "annotation"
            }]);
        var options = {
            legend: {
                position: 'none'
            },
            chartArea: { width: width, height: height, right: right },
            isStacked: true,
            orientation: orientation.orientation,
            colors: ['#008FBE', '#BE1E2D', '#00BD90'],
            fontSize: '12',
            fontName: 'OpenSans-Regular',
            hAxis: {
                viewWindowMode: 'maximized',
            },
            vAxis: {
                viewWindowMode: 'maximized',
            },
            animation: {
                startup: true,
                duration: 1500,
                easing: 'out',
            },
        };
        var chart = new google.visualization.ColumnChart(document.getElementById("currentStatusChart"));
        google.visualization.events.addListener(chart, 'ready', readyHandler);
        chart.draw(view, options);
