plotly - 响应宽度，固定高度

Question

我尝试制作一个适合可滚动父 div 的绘图图表：

data = {
          Name: {0:'name1', 1:'name2', 2: 'name3', 
                 3:'n4',4:'ewf',5:'dgag', 6:'faf', 7:'dfss',
                 8:'345',9:'9',10:'23435', 11:'2e345',12:'3345', 13:'a345', 
                 14:'34g5', 15:'3f45'},
          Count: {0:1023, 1:2345, 3:3875,4:234,5:3456, 6:84, 7:7763,
                  8:345,9:2345,10:2345, 11:2345,12:345, 13:345, 14:345, 
                  15:345},
          Index: {0:35, 1:200, 2:160, 3:24,4:234,5:356, 6:84, 7:73,
                  8:345,9:2345,10:2345, 11:2345,12:345, 13:345, 14:345, 
                  15:345}
       }
$('#p1').html("");
console.log(data)
Plotly.newPlot('p1',
    [{
        type: 'bar',
        x: Object.values(data.Count),
        y: Object.values(data.Name),
        base: 0,
        orientation: 'h'
    },{
        type: 'bar',
        x: Object.values(data.Index).map(function (e) {
            e = e-100
            return e
        }),
        y: Object.values(data.Name),
        base: 100,
        orientation: 'h',
        xaxis: 'x2',
        yaxis: 'y'
        
    },],
    {
        height: 10*2.3*Object.keys(data.Index).length,
        yaxis: {
            automargin: true,
            tickangle: 35
        },
        grid: {
            rows: 1,
            columns: 2,
            subplots: [['xy', 'x2y']]
        }
    },
    {
        responsive: true
    })

.col.tpcs{
    overflow-y: scroll;
    overflow-x: hidden;
    display: inline-block;
    height: 400px;
}

<div class="row loading pt-5 mt-md-3 mb-5">
   <div class="col tpcs" id='p1'></div>
</div>

根据此处的文档https://plot.ly/javascript/responsive-fluid-layout/，我创建了一个响应式绘图：

我希望绘图向下溢出，以便我可以向下滚动，但通过设置responsive: true，高度默认为#p1的大小，即400px。

有没有一种简单的方法可以只使宽度响应？我想将手动高度保持在 10*2.3*Object.keys(data.Index).length

将绘图设置为响应式，然后在调整父级大小时使用此函数（它会在浏览器中触发窗口调整大小事件）：

window.dispatchEvent(new Event('resize'));
