主要是对配置的一些说明,项目源码githup地址https://github.com/shengbid/echarts-series
看一下option的配置,除去series里面的配置,其他属性都是常见的配置,不多展开
option: { title: { text: '上证指数', left: 0 }, tooltip: { trigger: 'axis', axisPointer: { type: 'cross' } }, legend: { data: ['日K', 'MA5', 'MA10', 'MA20', 'MA30'] }, grid: { left: '10%', right: '10%', bottom: '15%' }, xAxis: { type: 'category', data: [], scale: true, boundaryGap: false, axisLine: {onZero: false}, splitLine: {show: false}, splitNumber: 20, min: 'dataMin', max: 'dataMax' }, yAxis: { scale: true, splitArea: { show: true } }, dataZoom: [ { type: 'inside', start: 50, end: 100 }, { show: true, type: 'slider', top: '90%', start: 50, end: 100 } ], }
主要看一下series配置里面的K线图,其他4组数据就是普通的折线图,先看一个注释掉K线图的效果,就是简单的多条折线图
OK,现在把其他4组数据注释,只留下K线图,就是现在这样
然后详细说明一下这里面的配置
data: k线图数据,格式[open, close, lowest, highest] (即:[开盘值, 收盘值, 最低值, 最高值]) 示例: data: [[11, 22, 33, 44], [12, 23, 34, 45]....]
itemStyle: 单个 K 线图数据的图形样式,默认阳线红色,阴线绿色
itemStyle: { color: '#ec0000', // 阳线颜色 color0: '#00da3c', // 阴线颜色 borderColor: '#8A0000', // 阳线边框颜色 borderColor0: '#008F28' // 阴线边框颜色 },
markPoint: 图表标注,就是图上4个圈圈标注
markPoint: {data: []}
data: [ // 有几组数据就有几个标注 { name: 'XX标点', // 标注名称,可不填,不会展示出来 coord: ['2013/5/31', 2300], // 标注的坐标X轴, Y轴 value: 2300, // 标注的数字 itemStyle: { color: 'rgb(41,60,85)' // 标注的颜色 } }, { name: 'highest value', // 特殊的标注类型,用于标注最大值最小值等 // 'min' 最小值。 // 'max' 最大值。 // 'average' 平均值 type: 'max', valueDim: 'highest' // K线图的取值维度open, close, lowest, highest }, { name: 'lowest value', type: 'min', valueDim: 'lowest' }, { name: 'average value on close', type: 'average', valueDim: 'close' } ],
markLine: 图表标线,就是图上三条虚线
markLine: { symbol: ['none', 'none'], // 线段两端的图表,默认开始是圆圈,结束是箭头 data: [ [ // 数组格式可以有两个值,表示线段的起点和终点 { name: 'from lowest to highest', type: 'min', valueDim: 'lowest', // K线图的取值维度open, close, lowest, highest symbol: 'circle', symbolSize: 10, label: { show: false }, emphasis: { label: { show: false } } }, { type: 'max', valueDim: 'highest', symbol: 'circle', symbolSize: 10, label: { show: false }, emphasis: { label: { show: false } } } ], { // 对象形式为直线 name: 'min line on close', type: 'min', valueDim: 'close' }, { name: 'max line on close', type: 'max', valueDim: 'close' } ] }
