javascript - plotly - 响应宽度，固定高度

Question

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

我希望绘图向下溢出，以便向下滚动，但通过设置响应: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

Answer 1

看起来情节还没有那个功能。我必须做的是制作一个完全响应的情节并将其包装到一个额外的嵌套 div 中，如下所示:

    <div class="row loading pt-5 mt-md-3 mb-5">
        <div class="col tpcs" id='p1wrap'>
            <div class="ph" id=p1></div>
        </div>
    </div>

然后我需要使 div 宽度响应其父 div:

   function resP(id){
    var d3 = Plotly.d3;

    var parent_width = $("#"+id).parent().width()
    var gd3 = d3.select(`div[id=${id}]`)
        .style({
            width: parent_width - 10,
            //'margin-right': (100 - WIDTH_IN_PERCENT_OF_PARENT) / 2 + 'vh',
            //'margin-top': (100 - HEIGHT_IN_PERCENT_OF_PARENT) / 2 + 'vh'
        });
    return gd3.node();
   }

   window.addEventListener('resize', function(){
    Plotly.Plots.resize( resP('p1') );
   })
