Highcharts系列数据不工作 [英] Highcharts series data not working

问题描述

我现有的数组如下：

"Issues": [{
    "Id": null,
    "Key": null,
    "Values": [{
        "Key": "Display Name",
        "Value": "Rya"
    }, {
        "Key": "UserName",
        "Value": "RH"
    }, {
        "Key": "Count",
        "Value": "350"
    }]
}, {
    "Id": null,
    "Key": null,
    "Values": [{
        "Key": "Display Name",
        "Value": "Mike"
    }, {
        "Key": "UserName",
        "Value": "ML"
    }, {
        "Key": "Count",
        "Value": "90"
    }]
}]

我想要的数组：

[{
    name: 'Rya', 
    value: 350
}, {
    name: 'Mike', 
    value: 90
}]

我尝试过：

Data.Issues.map(o=> o.Values.reduce((acc, {Key, Value}) =>
                                       (acc[Key] = Value, acc), {}));

this.donughtChartData1 = this.donughtChartData.map( ({UserName, Count}) => 
    ({ name: UserName, value: Count}) );

但这给了我：

[{
    "name": "RHanney",
    "value": "350"
}, { 
    "name": "MLuckenbill", 
    "value": "90"
}]

推荐答案

在代码的最后一行，添加一个 + before Count 所以它被转换成一个数字：

In the last line of your code, add a + before Count so it gets converted to a number:

// ...
({ name: UserName, value: +Count}) );

如何添加一个字符可以带来解决方案： - ）

How adding one character can bring the solution :-)
