1、问题背景 设计一条折线图,但是图形中不用插件自带的颜色,需要自定义线条和折点的颜色 2、实现源码 (1)图形自分配颜色 echarts-设置折线图中折线线条颜色和折线点颜色 body,html{ width: 99%; height: 99%; font-family: "微软雅黑"; font-size: 12px; } #line{ width: 100%; height: 100%; } $(function(){ var chart = document.getElementById('line'); var echart = echarts.init(chart); var option = { title: { text: '' }, tooltip: { trigger: 'axis' }, legend: { data:['销售量'] }, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, toolbox: { feature: { saveAsImage: {} } }, xAxis: { type: 'category', boundaryGap: false, data: ['周一','周二','周三','周四','周五','周六','周日'] }, yAxis: { type: 'value' }, series: [ { name:'销售量', type:'line', stack: '销售量', data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); (2)线条自定义颜色 echarts-设置折线图中折线线条颜色和折线点颜色 body,html{ width: 99%; height: 99%; font-family: "微软雅黑"; font-size: 12px; } #line{ width: 100%; height: 100%; } $(function(){ var chart = document.getElementById('line'); var echart = echarts.init(chart); var option = { title: { text: '' }, tooltip: { trigger: 'axis' }, legend: { data:['销售量'] }, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, toolbox: { feature: { saveAsImage: {} } }, xAxis: { type: 'category', boundaryGap: false, data: ['周一','周二','周三','周四','周五','周六','周日'] }, yAxis: { type: 'value' }, series: [ { name:'销售量', type:'line', stack: '销售量', itemStyle : { normal : { lineStyle:{ color:'#00FF00' } } }, data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); (3)折点自定义颜色 echarts-设置折线图中折线线条颜色和折线点颜色 body,html{ width: 99%; height: 99%; font-family: "微软雅黑"; font-size: 12px; } #line{ width: 100%; height: 100%; } $(function(){ var chart = document.getElementById('line'); var echart = echarts.init(chart); var option = { title: { text: '' }, tooltip: { trigger: 'axis' }, legend: { data:['销售量'] }, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, toolbox: { feature: { saveAsImage: {} } }, xAxis: { type: 'category', boundaryGap: false, data: ['周一','周二','周三','周四','周五','周六','周日'] }, yAxis: { type: 'value' }, series: [ { name:'销售量', type:'line', stack: '销售量', itemStyle : { normal : { color:'#00FF00', lineStyle:{ color:'#00FF00' } } }, data:[220, 132, 601, 314, 890, 230, 510] } ] }; echart.setOption(option); }); 3、实现结果(1)图形自分配颜色 (2)线条自定义颜色 (3)折点自定义颜色 4、问题说明 (1)设置折线线条颜色 lineStyle:{ color:'#00FF00' } (2)设置折线折点颜色 itemStyle : { normal : { color:'#00FF00' } } |
