echarts堆叠柱状图当设置barMinHeight的时候会超出显示区域echarts 配置项内容和展示

将浏览器窗口变小，当图表高度比较小的时候，Category 2的柱子会超出yAxis的最大值显示，有什么办法可以解决这个问题。

      app.title = '堆叠条形图';

option = {
    tooltip : {
        trigger: 'item',
        axisPointer : {            // 坐标轴指示器，坐标轴触发有效
            type : 'shadow'        // 默认为直线，可选为：'line' | 'shadow'
        }
    },
    
    grid: {
        show: false,
            left: 20,
            right: 75,
            bottom: 30,
            containLabel: true
    },
    yAxis:  {
        type: 'value',
        boundaryGap : true
    },
    xAxis: {
        type: 'category',
        data:["Cateogry 1","Category 2"]
    },
