// echarts-3D-bar-config.js
import Vue from vue;const echarts Vue.prototype.echarts;const CubeLeft echarts.graphic.extendShape({shape: {x: 0,y: 0},buildPath: function (ctx, shape) {const xAxisPoint shape.xAxisPoint;// 顶部右侧顶点const c1 [shape.x, shape.y];// 顶部左侧顶点const c2 [shape.x - 15, shape.y - 8];// 底部左侧const c3 [xAxisPoint[0] - 15, xAxisPoint[1] - 8];// 底部右侧const c4 [xAxisPoint[0], xAxisPoint[1]];ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath();}
});const CubeRight echarts.graphic.extendShape({shape: {x: 0,y: 0},buildPath: function (ctx, shape) {const xAxisPoint shape.xAxisPoint;// 顶部左侧顶点const c1 [shape.x, shape.y];// 底部左侧顶点const c2 [xAxisPoint[0], xAxisPoint[1]];// 底部右侧顶点const c3 [xAxisPoint[0] 15, xAxisPoint[1] - 8];// 顶部右侧顶点const c4 [shape.x 15, shape.y - 8];ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath();}
});const CubeTop echarts.graphic.extendShape({shape: {x: 0,y: 0},buildPath: function (ctx, shape) {// 底部顶点const c1 [shape.x, shape.y];// 右侧顶点const c2 [shape.x 15, shape.y - 8];// 顶部顶点const c3 [shape.x, shape.y - 15];// 右侧顶点const c4 [shape.x - 15, shape.y - 8];ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath();}
});
echarts.graphic.registerShape(CubeLeft, CubeLeft);
echarts.graphic.registerShape(CubeRight, CubeRight);
echarts.graphic.registerShape(CubeTop, CubeTop);然后在build-bar-option中引用即可 这里主要就是把series中的内容复制过来直接用就行了 import Vue from vue;
import ./echarts-3D-Bar-configconst echarts Vue.prototype.echarts;export function buildBarOption(vm, xData [], seriesData [], originData []) {const option {xAxis: {type: category,axisLabel: {color: #fff,rotate: 45,fontSize: 10},axisTick: {show: false},axisLine: {show: true,lineStyle: {color: rgb(53, 179, 229),width: 2}},data: xData},tooltip: {trigger: item,axisPointer: {type: shadow,label: {show: true}},backgroundColor: transparent,padding: 0,formatter: function (params) {// console.log(params)return div stylepadding: 15px; background: linear-gradient(180.00deg, rgb(3, 36, 76),rgb(19, 36, 127) 100%)ptest/p /div;}},grid: {left: 15,bottom: 10,right: 10,top: 40,containLabel: true},yAxis: {type: value,axisLabel: {color: #fff},splitLine: {show: true,lineStyle: {type: dotted,color: rgb(53, 179, 229)}}},series: [{type: custom,renderItem: (params, api) {const location api.coord([api.value(0), api.value(1)]);return {type: group,children: [{type: CubeLeft,shape: {api,xValue: api.value(0),yValue: api.value(1),x: location[0],y: location[1],xAxisPoint: api.coord([api.value(0), 0])},style: {fill: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{offset: 0,color: #3B80E2},{offset: 1,color: #49BEE5}])}},{type: CubeRight,shape: {api,xValue: api.value(0),yValue: api.value(1),x: location[0],y: location[1],xAxisPoint: api.coord([api.value(0), 0])},style: {fill: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{offset: 0,color: #3B80E2},{offset: 1,color: #49BEE5}])}},{type: CubeTop,shape: {api,xValue: api.value(0),yValue: api.value(1),x: location[0],y: location[1],xAxisPoint: api.coord([api.value(0), 0])},style: {fill: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{offset: 0,color: #3B80E2},{offset: 1,color: #49BEE5}])}}]};},data: seriesData},{data: seriesData,type: bar,barWidth: 13,itemStyle: {color: transparent}}]};return option;
