问题:
想实现下面的双柱图的效果,通过加一个折线图,这个折线图是两个指标值的差值,效果图如下:
解决方案:
差值是D4单元格减去C4单元格,然后基于这些数据作图,如下:
可以使用扩展属性实现,如下:
{ // //鼠标提示 // "tooltip": { // "show": true, // "backgroundColor": "#87cefa", // "formatter": "function(a){ debugger;return a.seriesName+'</br>'+a.data.displayValue}" // }, grid: [{ show: false, left: '10%', top: '15%', width: '40%', containLabel: true, bottom: 60 }, { show: false, left: '6%', top: 120, bottom: 60, width: '0%', }, { show: false, left: '50%', top: '15%', bottom: 60, containLabel: true, width: '40%', }], xAxis: [{ type: 'value', inverse: true, axisLabel: { show: true, color: '#979797', margin: 0 }, axisLine: { show: false }, axisTick: { show: false }, splitLine: { show: false } }, { gridIndex: 1, show: true, axisLabel: { color: '#979797', margin: 0 }, splitLine: { lineStyle: { color: '#979797', type: 'dashed' } } }, { gridIndex: 2, type: 'value', axisLabel: { show: true, color: '#979797', margin: 0 }, axisLine: { show: false }, axisTick: { show: false }, splitLine: { show: false } }], yAxis: [{ type: 'category', inverse: false, position: 'right', axisLabel: { show: false }, axisLine: { show: true, lineStyle: { color: '#979797' } }, axisTick: { show: false }, }, { type: 'category', inverse: false, gridIndex: 1, position: 'left', axisLabel: { align: 'left', padding: [8, 0, 0, 0], fontSize: 12, fontWeight: 500, }, axisLine: { show: false, lineStyle: { color: '#979797' } }, axisTick: { show: false }, }, { scale: false, type: 'category', inverse: false, gridIndex: 2, position: 'left', axisLabel: { show: false }, axisLine: { show: true, lineStyle: { color: '#979797' } }, axisTick: { show: false }, }], "series": [{ "name": "指标1", "type": "bar", "barWidth": 20, "itemStyle": { "normal": { "color": "#ff6600" }, "emphasis": { "color": "#ff9900" } }, // "stack": "default" }, { "name": "指标2", "type": "bar", "barWidth": 20, //控制现在在右边 xAxisIndex: 2, yAxisIndex: 2, "itemStyle": { "normal": { "color": "#ffcc33" }, "emphasis": { "color": "#ffff99" } }, // "stack": "default" }, { "name": "差值", "type": "line", //控制显示在右边 xAxisIndex: 2, yAxisIndex: 2, // "stack": "default" //线圆润显示 smooth: true, //去掉线上的点 symbol: 'none', //设置线的样式 "lineStyle": { "normal": { "color": "red", "width": 2, // shadowColor: 'rgba(0, 0, 0, 0.3)', //设置折线阴影 // shadowBlur: 15, // shadowOffsetY: 20, } }, //面积图渐变设置,可以自行调整颜色 "areaStyle": { "color": { "x": 0, "y": 0, "x2": 0, "y2": 1, "type": "linear", "global": false, "colorStops": [{ "offset": 0, "color": "rgba(255,0,0,0.5)" }, { "offset": 0.34, "color": "rgba(238,0,0,0.35)" }, { "offset": 1, "color": "rgba(238,0,0,0.20)" }] } } }] }
