如何使用高图指向数据中第二个索引的范围(dataClasses)?
How to point the range(dataClasses) for 2nd index in data using highcharts?
我已经使用 highchart 绘制了热图,但我想为 y 轴提供颜色范围,即数据数组中的第二个索引,但它自动采用第三个索引。
下面是 jsfiddle 代码。
colorAxis: {
dataClasses: [{
from: 0,
to: 10,
color: 'rgb(191, 27, 0)'
},{
from:10,
to:30,
color:'rgb(234, 100, 96)'
},{
from:30,
to:100,
color:'rgb(242, 201, 109)'
},{
from:100,
color:'rgb(98, 158, 81)'
}]
},
series: [{
name: 'Sales per employee',
borderWidth: 1,
data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67], [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117], [1, 4, 48], [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52], [3, 0, 72], [3, 1, 132], [3, 2, 114], [3, 3, 19], [3, 4, 16], [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115], [5, 0, 88], [5, 1, 32], [5, 2, 12], [5, 3, 6], [5, 4, 120], [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96], [7, 0, 31], [7, 1, 1], [7, 2, 82], [7, 3, 32], [7, 4, 30], [8, 0, 85], [8, 1, 97], [8, 2, 123], [8, 3, 64], [8, 4, 84], [9, 0, 47], [9, 1, 99], [9, 2, 31], [9, 3, 48], [9, 4, 91]],
dataLabels: {
enabled: true,
color: '#000000'
}
}]
实际数据格式如下
data: [[0, 0, 10], [0, 1, 19]]
现在范围是根据第二个索引绘制的,即 10,19,但我想根据第一个索引绘制,即 0,1。
更改将用于计算颜色的 属性(点对象)的默认名称:
Highcharts.seriesTypes.heatmap.prototype.colorKey = 'x'; // 'value' by default
