减少Highcharts中堆叠的条之间的空间

标签: javascript html highcharts

我在Highchart中创建了堆积列。

我使用pointWidth: 50来减小列条的宽度,但是堆叠条之间的间隔太大。

如何减少堆叠条之间的空间?

[更新的问题]

我也想在图例中显示堆栈名称,用户可以单击以显示堆栈名称以在图表中隐藏堆栈。可以吗?

您可以将groupPadding设置为较高的值,这将使该组的列一起移动。请注意,为pointWidth使用固定值会影响图表的响应度,但是您可以使用响应规则为特定的图表宽度自定义这些值:https://api.highcharts.com/highcharts/responsive

演示:https://jsfiddle.net/BlackLabel/we1rc5vg/

  plotOptions: {
    column: {
      stacking: 'normal',
    },
    series: {
      //stacking: 'normal',
      dataLabels: {
        formatter: function() {
          console.log(this);
          return this.series.name;
        },
        enabled: true,
        //allowOverlap: true,
        //align: 'right',
        color: '#fff',
        shadow: false,
        //x:-50,
        style: {
          fontSize: "8px",
          textShadow: "0px"
        }
      },
      //pointPadding: 0,
      pointWidth: 50,
      groupPadding: 0.2,
      stacking: 'normal',
      //colorByPoint: true,
      //showInLegend: false
    }
  },

编辑:

要创建堆栈图例项,您需要添加不包含数据的系列(创建图例按钮),并使用 legendItemClick 回调自定义按钮功能。

演示:https://jsfiddle.net/BlackLabel/qLs219u4/

请注意,当堆栈被隐藏并且用户将从隐藏的堆栈中单击特定的系列图例项目时,此解决方案可能无法完美运行。

一旦我完成了非常复杂的示例。如果您想知道,可以在这里探索这个主题:https://www.highcharts.com/forum/viewtopic.php?t=42157
