javascript - Highchart，具有多个系列的条形图

Question

如何显示包含多个系列的条形图:

http://jsfiddle.net/qyd6w5tx/1/

$(function () {
    $('#container').highcharts(


    {
        "chart": {
            "style": {
                "fontFamily": "Arial, sans-serif"

        },
            "xAxis": {
            "type": "category",
                "reversed": false,

            },
                "labels": {
                "format": "{value}%"
            },
                "index": 1,
                "min": -0.39,
                "max": 9.99

                },
                    "minPointLength": 2
            },

        },
            "credits": {
            "enabled": false
        },
            "series": [{
            "name": "Group A",
                "type": "bar",
                "format": "pct",
                "top_value": "",
                "min_percent": "",
                "style": {
                "abs": "display: none"
            },
                "data": [{
                "name": "Test 01",
                    "value": 0.8,
                    "percentage": 0.8,
                    "y": 0.8
            }, {
                "name": "Test 02",
                    "value": 2,
                    "percentage": 2,
                    "y": 2
            }, {
                "name": "Test 03",
                    "value": -0.5,
                    "percentage": -0.5,
                    "y": -0.5
            }, {
                "name": "Test 04",
                    "value": 2.33,
                    "percentage": 2.33,
                    "y": 2.33
            }],
                "yAxis": 1
        }, {
            "name": "Group B",
                "type": "bar",
                "format": "pct",
                "top_value": "",
                "min_percent": "",
                "style": {
                "abs": "display: none"
            },
                "data": [{
                "name": "Test 05",
                    "value": 9,
                    "percentage": 9,
                    "y": 9
            }, {
                "name": "Test 06",
                    "value": 9,
                    "percentage": 9,
                    "y": 9
            }, {
                "name": "Test 07",
                    "value": 3,
                    "percentage": 3,
                    "y": 3
            }],
                "yAxis": 1
        }],
            "title": {
            "text": "Test"
        }
    }




    );
});

在这个例子中，我想一个接一个地显示:

• 测试 01
• 测试 02
• 测试 03
• 测试 04
• 测试 05
• 测试 06
• 测试 07

然后将 A 组设置为蓝色，将 B 组设置为红色，并在图表下显示图例: - A组(蓝色) - B组(红色)

我对如何用 highchart 制作这个有点困惑......

感谢Rotan075了解我的问题并找到解决方案。 http://jsfiddle.net/hw5s4ahm/

实际上我没有指定需要为该系列保留相同的数据结构:

         "series": [{
            "name": "Group A",
                "type": "bar",
                "format": "pct",
                "top_value": "",
                "min_percent": "",
                "style": {
                "abs": "display: none"
            },
                "data": [{
                "name": "Test 01",
                    "value": 0.8,
                    "percentage": 0.8,
                    "y": 0.8
            }, {
                "name": "Test 02",
                    "value": 2,
                    "percentage": 2,
                    "y": 2
            }, {
                "name": "Test 03",
                    "value": -0.5,
                    "percentage": -0.5,
                    "y": -0.5
            }, {
                "name": "Test 04",
                    "value": 2.33,
                    "percentage": 2.33,
                    "y": 2.33
            }],
                "yAxis": 1
        }, {
            "name": "Group B",
                "type": "bar",
                "format": "pct",
                "top_value": "",
                "min_percent": "",
                "style": {
                "abs": "display: none"
            },
                "data": [{
                "name": "Test 05",
                    "value": 9,
                    "percentage": 9,
                    "y": 9
            }, {
                "name": "Test 06",
                    "value": 9,
                    "percentage": 9,
                    "y": 9
            }, {
                "name": "Test 07",
                    "value": 3,
                    "percentage": 3,
                    "y": 3
            }],
                "yAxis": 1
        }]

其余部分可以更改，但此数据是由第三方级别生成的，并且必须保持通用。我以为这只是一个设置问题，但它似乎要复杂得多。

我从你的代码中了解到的是，你有 A 组和 B 组的数据，对吧？您要做的就是制作两个长度相同的数据列表。如果特定组没有数据，则必须向其添加 null 值。否则，Highcharts 会为每个测试 x 合并 A 组和 B 组。

您需要的是this code (live on JSFiddle) :

$(function () {
    $('#container').highcharts(
    {
        chart: {
            type: 'column',
            inverted: true
        },

        plotOptions: {
            series: {
                dataLabels: {
                    enabled: true,
                    formatter:function() {                                                  
                        if(this.y > 0){
                            return this.y;
                            return this.point.y;   
                        }
                    }
                }
            }
        },
        yAxis: {
            allowDecimals: false,
            min: -1,
            labels: {
                formatter: function () {
                    return this.value + '%';
                }
            },
            title: {
                text: '   ',
                margin:40
            }
        },

        xAxis: {
            categories: ['Test1', 'Test2', 'Test3', 'Test4', 'Test5','Test6','Test7']


        },
        legend: {
            enabled: true,
            floating: true,
            verticalAlign: 'bottom',
            align:'middle',
            backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF',
            borderWidth: 1,
            y:10,
            x:350
        },

        series: [{
            name: 'GroupA',
            color: 'rgba(223, 83, 83, .5)',
            data: [{y:null},{y:null}, {y:null}, {y:null}, {y:2.9}, {y:0.5}, {y:1.5}]
        },{
            name: 'GroupB',
            color: 'rgba(119, 152, 191, .5)',
            data: [{y:6.5}, {y:3.9}, {y:8.5}, {y:6.6},{y:null},{y:null},{y:null}]            
        }],
            title: {
            text: "Test"
        }
    }

    );
});

附注为了将图例对齐在图表底部，我以一种相当黑客的方式做到了这一点。我仅使用空白作为标题文本，并将图例放在其上方。您可以将其修改为您想要的任何内容。
