echart 3 数据密集时，断点不显示问题
如上图最开始标识的两点是不显示的，配置处理代码如下（series中配置symbolSize: 1,showAllSymbol: true）：
myChart.showLoading(); $.get('data/asset/data/confidence-band.json', function (data) { myChart.hideLoading(); var base = -data.reduce(function (min, val) { return Math.floor(Math.min(min, val.l)); }, Infinity); myChart.setOption(option = { "title": { "codedata": "ERAB.NbrSuccEstab/ERAB.NbrAttEstab", "x": "left", "y": -10, "subtextStyle": { "fontSize": 12, "color": "#CAC5D4" } }, "tooltip": { "trigger": "axis" }, "grid": { "top": "72px", "bottom": "32px" }, "legend": { "data": [ "32UE_OFFICE(192.168.3.111)" ] }, "xAxis": [ { "type": "category", "boundaryGap": true, "data": [ "2017-10-12 00:00:00", "2017-10-12 00:15:00", "2017-10-12 00:30:00", "2017-10-12 00:45:00", "2017-10-12 01:00:00", "2017-10-12 01:15:00", "2017-10-12 01:30:00", "2017-10-12 01:45:00", "2017-10-12 02:00:00", "2017-10-12 02:15:00", "2017-10-12 02:30:00", "2017-10-12 02:45:00", "2017-10-12 03:00:00", "2017-10-12 03:15:00", "2017-10-12 03:30:00", "2017-10-12 03:45:00", "2017-10-12 04:00:00", "2017-10-12 04:15:00", "2017-10-12 04:30:00", "2017-10-12 04:45:00", "2017-10-12 05:00:00", "2017-10-12 05:15:00", "2017-10-12 05:30:00", "2017-10-12 05:45:00", "2017-10-12 06:00:00", "2017-10-12 06:15:00", "2017-10-12 06:30:00", "2017-10-12 06:45:00", "2017-10-12 07:00:00", "2017-10-12 07:15:00", "2017-10-12 07:30:00", "2017-10-12 07:45:00", "2017-10-12 08:00:00", "2017-10-12 08:15:00", "2017-10-12 08:30:00", "2017-10-12 08:45:00", "2017-10-12 09:00:00", "2017-10-12 09:15:00", "2017-10-12 09:30:00", "2017-10-12 09:45:00", "2017-10-12 10:00:00", "2017-10-12 10:15:00", "2017-10-12 10:30:00", "2017-10-12 10:45:00", "2017-10-12 11:00:00", "2017-10-12 11:15:00", "2017-10-12 11:30:00", "2017-10-12 11:45:00", "2017-10-12 12:00:00", "2017-10-12 12:15:00", "2017-10-12 12:30:00", "2017-10-12 12:45:00", "2017-10-12 13:00:00", "2017-10-12 13:15:00", "2017-10-12 13:30:00", "2017-10-12 13:45:00", "2017-10-12 14:00:00", "2017-10-12 14:15:00", "2017-10-12 14:30:00", "2017-10-12 14:45:00", "2017-10-12 15:00:00", "2017-10-12 15:15:00", "2017-10-12 15:30:00", "2017-10-12 15:45:00", "2017-10-12 16:00:00", "2017-10-12 16:15:00", "2017-10-12 16:30:00", "2017-10-12 16:45:00", "2017-10-12 17:00:00", "2017-10-12 17:15:00", "2017-10-12 17:30:00", "2017-10-12 17:45:00", "2017-10-12 18:00:00", "2017-10-12 18:15:00", "2017-10-12 18:30:00", "2017-10-12 18:45:00", "2017-10-12 19:00:00", "2017-10-12 19:15:00", "2017-10-12 19:30:00", "2017-10-12 19:45:00", "2017-10-12 20:00:00", "2017-10-12 20:15:00", "2017-10-12 20:30:00", "2017-10-12 20:45:00", "2017-10-12 21:00:00", "2017-10-12 21:15:00", "2017-10-12 21:30:00", "2017-10-12 21:45:00", "2017-10-12 22:00:00", "2017-10-12 22:15:00", "2017-10-12 22:30:00", "2017-10-12 22:45:00", "2017-10-12 23:00:00", "2017-10-12 23:15:00", "2017-10-12 23:30:00", "2017-10-12 23:45:00", "2017-10-13 00:00:00" ], "splitLine": { "show": false }, "name": "Hour" } ], "yAxis": [ { "name": "(%)", "type": "value", "axisLabel": { "formatter": "{value}" }, "min": 0 } ], "series": [ { "name": "32UE_OFFICE(192.168.3.111)", "type": "line", symbolSize: 1, showAllSymbol: true, "data": [ null, "", "", "", "", "", "", 90, "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", 70, "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", 100, 100, 100, "", "", "", "", "", "", null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null ] } ] } ); });
