前言
修改柱状图柱子背景色渐变和圆角,可通过修改series.itemstyle.normal.barborderradius属性实现圆角设置,series.itemstyle.normal.color:new echarts.graphic.lineargradient()来设置渐变色柱子。
效果图:
代码如下:
series: [{ data: data, type: 'bar', barwidth: '40%', itemstyle: { normal: { //这里设置柱形图圆角 [左上角,右上角,右下角,左下角] barborderradius:[5, 5, 0, 0], color: new echarts.graphic.lineargradient( 0, 1, 0, 0, [{//只要修改前四个参数就ok offset: 0, color: '#c6e6ca' }, //柱图渐变色 { offset: 1, color: '#45ac53' } ] ), }, }, }]
附:echarts绘制横向柱状图(圆角+渐变)
圆角配置
series: [ { name: '数量', type: 'bar', data: bardata, barwidth: 14, itemstyle: { emphasis: { barborderradius: 7 }, normal: { barborderradius: 7 } } } ]
渐变实现
设置itemstyle的color为new echarts.graphic.lineargradient()线性渐变即可. 这个api在官方文档里面都没找到, 经过测试前四个参数设置为0, 0, 1, 0可以从左到右渐变. 设置为0,0,0,1可以从上到下渐变. 第5个参数数组表示开始的颜色和结束的颜色.
itemstyle: { emphasis: { barborderradius: 7 }, normal: { barborderradius: 7, color: new echarts.graphic.lineargradient( 0, 0, 1, 0, [ {offset: 0, color: '#3977e6'}, {offset: 1, color: '#37bbf8'} ] ) } }
