生成的图像png文件中的小值被截断.但是在打印预览中没问题.

new Highcharts.Chart({
    chart: {
        renderTo: 'chart',
        type: 'pie'
    },
    title: { 
        text: 'My Chart title' 
    },
    plotOptions: {
        pie: {
            showInLegend: true,
            dataLabels: {
                enabled: true,
                formatter: function() {
                    return '<b>' + this.point.name + '</b>: ' + Math.round(this.point.total * this.point.percentage / 100);
                }
            }
        }
    },
    series: [{
        type: 'pie',
        name: 'Series name',
        data: [
            ["Lorem", 88],
            ["Lorem ipsum", 4],
            ["Praesent nibh nulla", 12],
            ["Lorem ipsum dolor sit amet", 66],
            ["Praesent fringilla suscipit molestie", 30],
            ["Donec at lectus at nulla viverra lobortis", 11],
            ["Class aptent taciti sociosqu ad litora", 87],
            ["Mauris vulputate sem id arcu volutpat fermentum", 149],
            ["Vestibulum faucibus lectus", 113],
            ["Pellentesque habitant morbi tristique", 7],
            ["Etiam lacinia mi suscipit", 92],
            ["Proin semper risus in lacus semper", 9],
            ["Fusce id faucibus massa", 99],
            ["Suspendisse", 4],
            ["Quisque quis lectus et turpis laoreet", 101]
        ]
    }],
    exporting: {
        enabled: true
    }
});

Answer 1

这是因为Highcharts没有检测width到容器.

您可以通过在选项sourceWidth中添加选项来解决此问题exporting:

exporting: {
    enabled: true,
    sourceWidth: 900
}

如果图表在页面加载时稍微被截断,那么它似乎是sourceWidth初始化的width,除非您在选项中指定它,否则在导出时它将是相同的.

我更新了jsFiddle给你一个这样工作的例子:http://jsfiddle.net/6afyH/2/
