将 y 轴标签作为 x 轴类别的 10%

Question

如何将 yAxis 标签作为图表 xAxis 中定义的 10% 的类别。例如，如果我有像 [2010,2011,2012,2013,....] 这样的类别，那么 yAxis 标签应该像 201.0, 201.1, 201.2, ...

这里我有预定义类别的基本图表

chart: {
        type: 'spline'
    },
    xAxis: {
        categories: [1340,1590,1379,1451,1671]
    },
    yAxis: {
        title: {
            text: '10% of Range'
        }
    },
    series: [{
        name: 'Tokyo',
        data: [7.0, 6.9, 9.5, 14.5, 18.4]
    }]
}

如何将 yAxis 绘图值作为 xAxis 类别的 10%，有什么方法吗？ 此外，我将从服务器接收系列和类别，因此类别将是数字。

我不能说我理解您为什么要这样做，无论如何，这是可能的。您可以使用load event 动态添加 10% 的 xAxis 作为 yAxis。像这样：

chart: {
  events: {
    load: function() {
      this.yAxis[0].update({type: 'categories', categories: this.xAxis[0].categories.map(function(x) { return x/10; }), tickPositions: this.xAxis[0].categories.map(function(x) { return x/10; })}, true)
    }
  }
},

Highcharts.chart('container', {
		chart: {
    	events: {
      	load: function() {
          this.yAxis[0].update({type: 'categories', categories: this.xAxis[0].categories.map(function(x) { return x/10; }), tickPositions: this.xAxis[0].categories.map(function(x) { return x/10; })}, true)
        }
      }
    },

    title: {
        text: 'Solar Employment Growth by Sector, 2010-2016'
    },

    subtitle: {
        text: 'Source: thesolarfoundation.com'
    },
		xAxis: {
    	type: 'categories',
    	categories: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
    },
    yAxis: {
        title: {
            text: 'Number of Employees'
        }
    },
    legend: {
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'middle'
    },

    plotOptions: {
        series: {
            label: {
                connectorAllowed: false
            }
        }
    },

    series: [{
        name: 'Manufacturing',
        data: [24916, 24064, 29742, 29851, 32490, 30282, 38121, 40434]
    }, {
        name: 'Sales & Distribution',
        data: [11744, 17722, 16005, 19771, 20185, 24377, 32147, 39387]
    }, {
        name: 'Project Development',
        data: [null, null, 7988, 12169, 15112, 22452, 34400, 34227]
    }, {
        name: 'Other',
        data: [12908, 5948, 8105, 11248, 8989, 11816, 18274, 18111]
    }],

});
