eCharts 如何獲取 xAxis 數據

Question

我在 echart.js 中有一些帶有點擊事件的代碼，就像這樣

mytempChart2.on('click', function (params) 
        //params.seriesName return aktif/non aktif
        {window.open('' + encodeURIComponent(params.dataType) + '.html', '_self');
    });

我在https://www.echartsjs.com/en/tutorial.html#Events%20and%20Actions%20in%20ECharts上閱讀了文檔 echart

但我沒有找到獲取 xAxis 數據的參數，我圖表上的 xAxis 數據是日期。

看我的圖片我想得到這個值（紅色圓圈）

您可以使用您指定的 params object 。 您需要訪問保存 x 軸上的值的name屬性。

請在下面找到工作代碼：

 // 基於准備好的dom，初始化echarts實例var myChart = echarts.init(document.getElementById('main')); option = { xAxis: [{ type: 'category', boundaryGap: false, data: [01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, ], }], yAxis: [{ type: 'value', axisLabel: { formatter: '{value}' } }], series: [{ name: 'Non-Aktif', type: 'line', data: [0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ], markPoint: { data: [{ name: 'tanggal', value: 100 }, { type: 'max', name: 'Tertinggi' }, { type: 'min', name: 'Terendah' } ] }, itemStyle: { normal: { lineStyle: { shadowColor: 'rgba(0,0,0,0.3)', shadowBlur: 10, shadowOffsetX: 8, shadowOffsetY: 8 } } }, markLine: { data: [{ type: 'average', name: 'Rata-rata' }] } }, { name: 'Aktif Kembali', type: 'line', data: [0, 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ], markPoint: { data: [{ type: 'max', name: 'Tertinggi' }, { type: 'min', name: 'Terendah' } ] }, itemStyle: { normal: { lineStyle: { shadowColor: 'rgba(0,0,0,0.3)', shadowBlur: 10, shadowOffsetX: 8, shadowOffsetY: 8 } } }, markLine: { data: [{ type: 'average', name: 'Rata-rata' }] } } ] } // 使用剛指定的配置項和數據顯示圖表。 myChart.setOption(option); myChart.on('click', function(params) { console.log(params.name); });
