  • 导出highcharts图表到Csv(Xls)

    我想要将highcharts图表的数据导入到表格,就可以使用这个方法。

    还是初始化图表:

    var chart = Highcharts.chart('container', {
                title: {
                    text: '2010 ~ 2016 年太阳能行业就业人员发展情况'
                },
                subtitle: {
                    text: '数据来源:thesolarfoundation.com'
                },
                yAxis: {
                    title: {
                        text: '就业人数'
                    }
                },
                legend: {
                    layout: 'vertical',
                    align: 'right',
                    verticalAlign: 'middle'
                },
                plotOptions: {
                    series: {
                        label: {
                            connectorAllowed: false
                        },
                        pointStart: 2010
                    }
                },
                series: [{
                    name: '安装,实施人员',
                    data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
                }, {
                    name: '工人',
                    data: [24916, 24064, 29742, 29851, 32490, 30282, 38121, 40434]
                }, {
                    name: '销售',
                    data: [11744, 17722, 16005, 19771, 20185, 24377, 32147, 39387]
                }, {
                    name: '项目开发',
                    data: [null, null, 7988, 12169, 15112, 22452, 34400, 34227]
                }, {
                    name: '其他',
                    data: [12908, 5948, 8105, 11248, 8989, 11816, 18274, 18111]
                }],
                responsive: {
                    rules: [{
                        condition: {
                            maxWidth: 500
                        },
                        chartOptions: {
                            legend: {
                                layout: 'horizontal',
                                align: 'center',
                                verticalAlign: 'bottom'
                            }
                        }
                    }]
                }
            });

    需要用到export-csv.js文件,复制,粘贴,改名,ok:

                    return window.btoa(unescape(encodeURIComponent(s))); // #50
                };
            getContent(
                this,

            if (!this.insertedTable) {
                var div = document.createElement('div');
                div.className = 'highcharts-data-table';
                // Insert after the chart container
                this.renderTo.parentNode.insertBefore(div, this.renderTo.nextSibling);

        // Add "Download CSV" to the exporting menu. Use download attribute if supported, else
        // run a simple PHP script that returns a file. The source code for the PHP script can be viewed at
        // https://raw.github.com/highslide-software/highcharts.com/master/studies/csv-export/csv.php
        if (Highcharts.getOptions().exporting) {
            Highcharts.getOptions().exporting.buttons.contextButton.menuItems.push({
                textKey: 'downloadCSV',
                onclick: function () { this.downloadCSV(); }
            }, {
                textKey: 'downloadXLS',
                onclick: function () { this.downloadXLS(); }
            }, {
                textKey: 'viewData',
                onclick: function () { this.viewData(); }
            });
        }
     
        // Series specific
        if (seriesTypes.map) {
            seriesTypes.map.prototype.exportKey = 'name';
        }
        if (seriesTypes.mapbubble) {
            seriesTypes.mapbubble.prototype.exportKey = 'name';
        }
     
    });

    最后加上一句话,搞定:

    $('#button').click(function () {
                chart.downloadCSV();
           //chart.downloadXLS(); }
