Highcharts中堆积柱形图中的重叠和圆角堆栈

Question

我正在尝试实现类似于 2014 年专栏的目标，但我还没有找到一种方法来提供这样的分层。 This 是我迄今为止所拥有的。


我需要制作一个看起来像 2014 年列或 2015 年列的堆叠柱形图。（可行）

• 第 2014 列的问题是我无法找到任何属性来提供（负）边距以实现上述结果。

• 2015 列的问题是我无法单独为左上角和右上角添加边框半径。
  

由于fiddle的链接必须附上代码

Highcharts.chart('container', {
  chart: {
    type: 'column',

要实现 2014 的结果，您可以使用 highchart wrapper，并更改点的绘制方式，如下所示：

(function (H) {
  H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function (proceed) {
    $.each(this.points, function (i,point) {
      let borderRadius = this.options.borderRadius;
      point.shapeArgs.y -=  borderRadius; //move the point down by borderRadius pixels
      point.shapeArgs.height +=  borderRadius; //add borderRadius pixels to the total height of a point (to cover the gap)
    });
    proceed.apply(this, Array.prototype.slice.call(arguments, 1));
  });
}(Highcharts));

    (function (H) {
      H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function (proceed) {
        let seriesIndex = this.index
        $.each(this.points, function (i,point) {
        	point.shapeArgs.y -= seriesIndex == 0 ? 0 : 5; //if it is not the first series, then move the series down 5 pixels
            point.shapeArgs.height +=  5; //add 5 pixels to the total height(to cover the gap)
          });
          proceed.apply(this, Array.prototype.slice.call(arguments, 1));
        });
    }(Highcharts));

Highcharts.chart('container', {
  chart: {
    type: 'column',
    spacingBottom: 0
  },
  title: {
    text: ''
  },
  xAxis: {
    categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'],
    offset: 7,
    lineWidth: 0,
    tickLength: 0
  },
  yAxis: {
    min: 0,
    title: {
      text: ''
    },
    stackLabels: {
      enabled: false,
      style: {
        fontWeight: 'bold',
        color: 'gray'
      }
    },
    visible: false
  },
  legend: {
    align: 'center',

    verticalAlign: 'bottom',

  },
  tooltip: {
    headerFormat: '<b>{point.x}</b><br/>',
    pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
  },
  plotOptions: {
    series: {

    },
    column: {
      stacking: 'normal',
      borderWidth: 0,
      borderRadius: 5,
      dataLabels: {
        enabled: true,
        color: 'white'
      }
    }
  },
  series: [{
    name: 'John',
    data: [5, 3, 4, 7, 2],

  }, {
    name: 'Jane',
    data: [2, 2, 3, 2, 1]
  }, {
    name: 'Joe',
    data: [3, 4, 4, 2, 5]
  }]
});

如果您想要 2015 结果，请使用相同的函数，如下所示：

(function(H) {
  H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function(proceed) {
    let seriesIndex = this.index,
      firstIndex = this.chart.series[0].index,
      lastIndex = this.chart.series[this.chart.series.length - 1].index,
      borderRadius = this.options.borderRadius;

    this.options.borderRadius = 0; //Remove the border radius

    $.each(this.points, function(i, point) {
      if (seriesIndex != firstIndex && seriesIndex != lastIndex) {
        point.shapeArgs.y -= borderRadius; //make sure the middle points cover the outer points
        point.shapeArgs.height += borderRadius*2; 
      }
    });

    proceed.apply(this, Array.prototype.slice.call(arguments, 1));

    $.each(this.points, function(i, point) {
      if (seriesIndex == firstIndex || seriesIndex == lastIndex) {
        point.graphic.attr({
          r: borderRadius //set the borer radius to be whatever it was before to only the outer points
        });
      }
    });
  });
}(Highcharts));

我手动设置了系列的 zIndex，但也可以这样做。只是现在没有时间寻找设置它的位置。

(function(H) {
  H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function(proceed) {
    let seriesIndex = this.index,
      firstIndex = this.chart.series[0].index,
      lastIndex = this.chart.series[this.chart.series.length - 1].index,
      borderRadius = this.options.borderRadius;

    this.options.borderRadius = 0; //Remove the border radius

    $.each(this.points, function(i, point) {
      if (seriesIndex != firstIndex && seriesIndex != lastIndex) {
        point.shapeArgs.y -= borderRadius; //make sure the middle points cover the outer points
        point.shapeArgs.height += borderRadius*2; 
      }
    });

    proceed.apply(this, Array.prototype.slice.call(arguments, 1));

    $.each(this.points, function(i, point) {
      if (seriesIndex == firstIndex || seriesIndex == lastIndex) {
        point.graphic.attr({
          r: borderRadius //set the borer radius to be whatever it was before to only the outer points
        });
      }
    });
  });
}(Highcharts));

Highcharts.chart('container', {
  chart: {

还请注意，我在此处操作函数 drawPoints，并且正如文档所述，它仅在开始时运行一次。因此，如果您开始禁用/启用系列，那么它们的外观不一定会像您期望的那样。

要获得 2015 年的结果，您可以使用此 rounded-corners.js 插件：https://rawgit.com/highcharts/rounded-corners/master/rounded-corners.js

series: [{
  data: [307, 231, 335, 203],
  borderRadiusTopLeft: '20px',
  borderRadiusTopRight: '20px'
}, {
  data: [183, 196, 547, 408]
}, {
  data: [414, 441, 514, 627],
  borderRadiusBottomLeft: '20px',
  borderRadiusBottomRight: '20px'
}]
