Recharts

Question

我对 React 和 Recharts 都很陌生，而且我有点进退两难。我做了很多阅读，但似乎找不到我要找的东西，所以我希望能在这里得到一些帮助。

我有一个数据集，其中包含具有已完成、失败和进行中状态的进程列表，我想显示堆叠条形图但要对其进行标准化 - 即它们都需要具有相同的宽度。我设法使它的大部分工作正常，但事实证明在条形图上显示值很痛苦。

下面是我的代码：

export default class DashboardView extends React.Component<IDashboardView, {}>{
render() {
    const { dashboard, onDashboardItemClick } = this.props;

    const data = [
        {name: 'NE Send', completed: 230, failed: 335, inprogress: 453},
        {name: 'NE Resend', completed: 335, failed: 330, inprogress: 345},
        {name: 'Miles Orchestrator', completed: 537, failed: 243, inprogress: 2110},
        {name: 'Commissions Payment Orch', completed: 132, failed: 328, inprogress: 540},
        {name: 'Business Integrators', completed: 530, failed: 145, inprogress: 335},
        {name: 'SmartTrack', completed: 538, failed: 312, inprogress: 110}
    ];

    const CustomizedLabel = React.createClass({
        render () {
            const {x, y, value, dataKey} = this.props;                
            const fullValue =  value; //(value[1] - value[0]);
            return <text x={x-20}  y={y+5}  dy={0} fontSize='12' fill="#FFFFFF" fontWeight="Bold" textAnchor="start">{fullValue}</text>
        }
    });
    
    return (
        <div className="content c-white">
            <h1>Dashboard</h1>
            <ResponsiveContainer height={250} width={'100%'}>
                <BarChart layout="vertical" data={data} margin={{left: 50, right: 50}} stackOffset="expand">
                    <XAxis hide type="number"/>
                    <YAxis type="category" dataKey="name" stroke="#FFFFFF" fontSize="12" />
                    <Tooltip/>
                    <Bar dataKey="failed" fill="#dd7876" stackId="a" label={<CustomizedLabel />} />
                    <Bar dataKey="completed" fill="#82ba7f" stackId="a" label={<CustomizedLabel/>} />
                    <Bar dataKey="inprogress" fill="#76a8dd" stackId="a" label={<CustomizedLabel/>} />
                </BarChart>
            </ResponsiveContainer>
        </div>
    );
}
}

结果如下：正如您所看到的，数字是......好吧......奇数，只有当我添加 stackOffset="expand" 属性时才会发生这种情况。

我如何才能将部分的实际值获取到我的标签而不是基于 stackOffset 的计算值？我显示的值是两个值的数组，我尝试对这些值进行一些操作但没有成功。

任何帮助将不胜感激。
