Question

该系列的数据点数组。对于热图系列类型，可以通过以下方式给出点：HighChart Api

An array of arrays with 3 or 2 values. In this case, the values correspond to x,y,value. If the first value is a string, it is applied as the name of the point, and the x value is inferred. The x value can also be omitted, in which case the inner arrays should be of length 2. Then the x value is automatically calculated, either starting at 0 and incremented by 1, or from pointStart and pointInterval given in the series options.

data: [
    [0, 9, 7],
    [1, 10, 4],
    [2, 6, 3]
]
An array of objects with named values. The objects are point configuration objects as seen below. If the total number of data points exceeds the series' turboThreshold, this option is not available.

data: [{
    x: 1,
    y: 3,
    value: 10,
    name: "Point2",
    color: "#00FF00"
}, {
    x: 1,
    y: 7,
    value: 10,
    name: "Point1",
    color: "#FF00FF"
}]

我根据提供的Here，

示例创建了一个

紧随其后是我修改过的 Fiddle显示代表我的数据。

The things I want to achieve it.
1. Configure Data from Json Objects (Instead of CSV)
2. Currently 3 values are for a point i.e.( x,y,value) eg. 1,0,0.5
3. I want to add 2 more values ( x,y,value,name,color) eg. 1,0,0.5,"My Text","Green"

Answer 1

使用tooltip.formatter格式化tooltip字符串。我添加了json而不是csv，我还添加了额外的数据名称，颜色。这反映在工具提示上。

var myJson=
[{x:1,y:0,value:1.3,name:'a',color:'#fff'},
{x:1,y:1,value:1.6,name:'b',color:'#ccc'},
{x:1,y:2,value:1.0,name:'c',color:'#eee'},
{x:1,y:3,value:1.1,name:'d',color:'#ddd'},
{x:1,y:4,value:1.7,name:'e',color:'#yyy'}]


var chart;
 chart= new Highcharts.chart('container', {
    chart: {
        events: {
            load: function () {
console.log(this)
            }
        }
    },
tooltip: {
        formatter: function () {
       //console.log(this)
            return 'The value for x is <b>' + this.point.x +
                '</b> and y is <b>' + this.point.y + '</b>'+
                '</b> and name is <b>' + this.point.options.name + '</b>'+
                '</b> and color is <b>' + this.point.options.color + '</b>'+
