在分组堆积的条形图中隐藏空条-chart.js

我正在使用2.5.0版的chart.js，需要知道是否有任何方法可以隐藏成组的堆叠条形图中每个组的空条吗？图表数据集中的某些数据值可以为null。

这是我想要的： 组合图类型（分组和堆叠）

    var optiOns= {

                var dataset = data.datasets[tooltipItem.datasetIndex];

                if (tooltipItem.index == 0 && tooltipItem.datasetIndex !== 0)
                    return null;

                return dataset.label + ': ' + numeral(dataset.data[tooltipItem.index]).format('($ 0.0 a)');
            }
        }
    },
