javascript - bar pointPlacement 在获取一个数据时效果不佳

问题描述

pointPlacement当数据大于 1时使用in highcharts 时，它工作正常，但是当从服务器获取一个数据时，所有条形压缩到一个条形。

对不起我的英语不好

Highcharts.chart('container', {
  chart: {
    type: 'column'
  },
  title: {
    text: 'Efficiency Optimization by Branch'
  },
  xAxis: {
    categories: [
      'Seattle HQ',
      'San Francisco',
      'Tokyo'
    ]
  },
  yAxis: [{
    min: 0,
    title: {
      text: 'Employees'
    }
  }, {
    title: {
      text: 'Profit (millions)'
    },
    opposite: true
  }],
  legend: {
    shadow: false
  },
  tooltip: {
    shared: true
  },
  plotOptions: {
    column: {
      grouping: false,
      shadow: false,
      borderWidth: 0
    }
  },
  series: [{
    name: 'Employees',
    color: 'rgba(165,170,217,1)',
    data: [150],
    pointPadding: 0.3,
    pointPlacement: -0.2
  }, {
    name: 'Employees Optimized',
    color: 'rgba(126,86,134,.9)',
    data: [140],
    pointPadding: 0.4,
    pointPlacement: -0.2
  }, {
    name: 'Profit',
    color: 'rgba(248,161,63,1)',
    data: [183.6],
    tooltip: {
      valuePrefix: '$',
      valueSuffix: ' M'
    },
    pointPadding: 0.3,
    pointPlacement: 0.2,
    yAxis: 1
  }, {
    name: 'Profit Optimized',
    color: 'rgba(186,60,61,.9)',
    data: [203.6],
    tooltip: {
      valuePrefix: '$',
      valueSuffix: ' M'
    },
    pointPadding: 0.4,
    pointPlacement: 0.2,
    yAxis: 1
  }]
});

解决方案

这是此处报告的 Highcharts 错误：https ://github.com/highcharts/highcharts/issues/11800

作为一种解决方法，您可以设置pointRange: 1：

plotOptions: {
    column: {
        pointRange: 1,
        ...
    }
}
