react-native - Victory-native 的 VictoryBar 标签显示不正确

Question

我无法让我的 VictoryBar 图表在我的 React Native 应用程序中正确显示标签。x 轴代表天数，y 轴代表数值。我希望图表在每个条形上方显示值，但它显示的是当天。我已经设置了标签属性，但它什么也没做。如图所示，当我 console.log(d) 时没有任何反应。这段代码的结果如下。

“react-native”：“0.59.9” “victory-native”：“^32.0.2” “react-native-svg”：“^9.5.1”，

谢谢

<VictoryChart domainPadding={70}>
  <VictoryBar 
     data={bars} 
     x="label"  
     y="value"
     // animate={{ onLoad: { duration: 1000 } }}
     style={{ data: { width: 20, fill: (d) => d.x === 3 ? "#000000" : "#49C6B7" }}}
     labels={(d)=>{console.log(d);return d.y}}
  />
  <VictoryAxis
    //x
    tickLabelComponent={<VictoryLabel angle={45} />}
    style={{
      axis: {stroke: 'grey'},
      ticks: {stroke: 'white'},
      tickLabels: {fontSize: 12, padding: 3, marginLeft:10, stroke:"white", verticalAnchor: "middle", textAnchor:'start'}
    }}
  />
  <VictoryAxis
  //y
    tickFormat={(d)=> numeral(d).format('0.0a')}
    dependentAxis
    style={{
    axis: {stroke: "grey"},
    grid: {stroke:'grey'},
    tickLabels: {fontSize: 0, padding: 0,   stroke:'white'}
    }}
  />
</VictoryChart>

labels={({ datum }) => `${datum.y}`}
