jquery - Highcharts，钻取时添加 'go back'(向上钻取)按钮

Question

如何实现此 http://jsfiddle.net/highcharts/Vf3yT/ 中的“<返回”按钮(点击饼图)到这个http://jsfiddle.net/neFYY/ (新 3.0 Highcharts)？

Highcharts.setOptions({
    lang: {
        drillUpText: '◁ Back to {series.name}'
    }
});

Answer 1

让我们说清楚:

• 此示例:http://jsfiddle.net/neFYY/2/不是插件，它只是简单的 Highcharts 图表，带有一些点击绑定(bind)以使其表现得像向下钻取。

• 此示例:http://jsfiddle.net/highcharts/Vf3yT/ IS 插件，需要一些特定的结构才能使其工作(请参阅:drilldown 对象)

因此，如果您想将插件与第一个图表一起使用，您需要为该插件传递正确的结构，即:

drilldown: {
    activeAxisLabelStyle: {
        cursor: 'pointer',
        color: '#039',
        fontWeight: 'bold',
        textDecoration: 'underline'            
    },
    activeDataLabelStyle: {
        cursor: 'pointer',
        color: '#039',
        fontWeight: 'bold',
        textDecoration: 'underline'            
    },
    animation: {
        duration: 500
    },
    series: [{
        id: 'fruits',
        name: 'Fruits',
        data: [
            ['Apples', 4],
            ['Pears', 6],
            ['Oranges', 2],
            ['Grapes', 8]
        ]
    }, {
        id: 'cars',
        name: 'Cars',
        data: [{
            name: 'Toyota', 
            y: 4,
            drilldown: 'toyota'
        },
        ['Volkswagen', 3],
        ['Opel', 5]
        ]
    }, {
        id: 'toyota',
        name: 'Toyota',
        data: [
            ['RAV4', 3],
            ['Corolla', 1],
            ['Carina', 4],
            ['Land Cruiser', 5]
        ]
    }]
},

及系列:

series: [{
    name: 'Overview',
    colorByPoint: true,
    data: [{
        name: 'Fruits',
        y: 10,
        drilldown: 'fruits'
    }, {
        name: 'Cars',
        y: 12,
        drilldown: 'cars'
    }, {
        name: 'Countries',
        y: 8
    }]
}]
