Question

我的HighCharts可以正常使用data内的数据作为序列，但我希望以data_New这样的格式提供数据。如何更改我的HighChart设置以接受该格式？ JSFiddle

var data = [{
  name: 'Apples',
  data: [5, 3, 4, 7, 2]
}, {
  name: 'Oranges',
  data: [2, 2, 3, 2, 1]
}, {
  name: 'Plums',
  data: [3, 4, 4, 2, 5]
}];

var data_New = [{
    name: 'John',
    Apples: 5,
    Oranges: 2,
    Plums: 3
  }, {
    name: 'Peter',
    Apples: 3,
    Oranges: 2,
    Plums: 4
  }, {
    name: 'William',
    Apples: 4,
    Oranges: 3,
    Plums: 4
  },
  {
    name: 'Chris',
    Apples: 7,
    Oranges: 2,
    Plums: 2
  },
  {
    name: 'Mike',
    Apples: 2,
    Oranges: 1,
    Plums: 5
  }
];


Highcharts.chart('container', {
  chart: {
    type: 'column'
  },
  title: {
    text: 'Stacked column chart'
  },
  xAxis: {
    categories: ['John', 'Peter', 'William', 'Chris', 'Mike']
  },
  yAxis: {
    min: 0,
    title: {
      text: 'Total fruit consumption'
    }
  },
  tooltip: {
    pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.percentage:.0f}%)<br/>',
    shared: true
  },
  plotOptions: {
    column: {
      stacking: 'percent'
    }
  },
  series: data_New
});

<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

Answer 1

Highcharts接受3种类型的数据集（Series）。

在您的情况下，最简单的方法是使用Array.from()将您的data_New转换为Higcharts接受的结构。

示例：

＆＃13;

var data_New = [{
        name: 'John',
        Apples: 5,
        Oranges: 2,
        Plums: 3
    }, {
        name: 'Peter',
        Apples: 3,
        Oranges: 2,
        Plums: 4
    }, {
        name: 'William',
        Apples: 4,
        Oranges: 3,
        Plums: 4
    },
    {
        name: 'Chris',
        Apples: 7,
        Oranges: 2,
        Plums: 2
    },
    {
        name: 'Mike',
        Apples: 2,
        Oranges: 1,
        Plums: 5
    }];
    

var data = [{
  name: 'Apples',
  data: Array.from(data_New, function(a){ return a.Apples})
},{
  name: 'Oranges',
  data: Array.from(data_New, function(a){ return a.Oranges})
},{
  name: 'Plums',
  data: Array.from(data_New, function(a){ return a.Plums})
}]

console.log(data)

您的更新fiddle。

如果你有可变数据集结构，想要从第一个属性创建类别，从其他属性创建数据集，那就更抽象了：

＆＃13;

var data_New = [{
        name: 'John',
        Apples: 5,
        Oranges: 2,
        Plums: 3
    }, {
        name: 'Peter',
        Apples: 3,
        Oranges: 2,
        Plums: 4
    }, {
        name: 'William',
        Apples: 4,
        Oranges: 3,
        Plums: 4
    },
    {
        name: 'Chris',
        Apples: 7,
        Oranges: 2,
        Plums: 2
    },
    {
        name: 'Mike',
        Apples: 2,
        Oranges: 1,
        Plums: 5
    }];

// make categories from first property values
var firstProp = Object.keys(data_New[0])[0],
    categories = Array.from(data_New, function(x){ return x[firstProp] });

// make data from all properties except first
var data = [];
for (i = 1; i < Object.keys(data_New[0]).length; i++) {
  var prop = Object.keys(data_New[0])[i];
  data.push({
    name : prop,
    data : Array.from(data_New, function(x){ return x[prop] })
  })
}   
console.log('categories:',categories,'\ndata:', data);

＆＃13;

唯一的条件是所有对象共享相同的数据结构。

Answer 2

您可以轻松地将数据转换为Highcharts with Array.prototype.map

接受的格式

sql = 'select RLAMBD from ' + OPTable
cursor.execute(sql)
print cursor.fetchone().RLAMBD
