参考的立体柱状图echarts category配置项内容和展示
配置项如下
// 绘制左侧面
const wid = 30;
const w1 = Math.sin(Math.PI/6) * wid; //4
const w2 = Math.sin(Math.PI/3) * wid; // 6.8
const snapHeight = wid / 4;
const CubeLeft = echarts.graphic.extendShape({
shape: {
x: 0,
y: 0
},
buildPath: function(ctx, shape) {
// 会canvas的应该都能看得懂，shape是从custom传入的
const xAxisPoint = shape.xAxisPoint
const c0 = [shape.x, shape.y ]
const c1 = [shape.x - w2, shape.y ]
const c2 = [shape.x - w2, xAxisPoint[1]]
const c3 = [shape.x, xAxisPoint[1]]
ctx.moveTo(c0[0], c0[1]).lineTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).closePath()
}
})
// 绘制右侧面
const CubeRight = echarts.graphic.extendShape({
shape: {
x: 0,
y: 0
},
buildPath: function(ctx, shape) {
const xAxisPoint = shape.xAxisPoint
const c1 = [shape.x, shape.y]
const c2 = [shape.x, xAxisPoint[1] ]
const c3 = [shape.x + w1, xAxisPoint[1] - w2 + snapHeight]
const c4 = [shape.x + w1, shape.y - w2 + snapHeight]
ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath()
}
})
// 绘制顶面
const CubeTop = echarts.graphic.extendShape({
shape: {
x: 0,
y: 0
},
buildPath: function(ctx, shape) {
const c1 = [shape.x, shape.y ]
const c2 = [shape.x + w1, shape.y - w2 + snapHeight ] //右点
const c3 = [shape.x - w2 + w1, shape.y - w2 + snapHeight ]
const c4 = [shape.x - w2, shape.y ]
ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath()
}
})
