echarts 语文配置项内容和展示
使用timeline切换series 数据 会遗留上一个option里的数据，如柱状图中的折线图
配置项如下
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 - 13, shape.y - 13]
const c2 = [xAxisPoint[0] - 13, xAxisPoint[1] - 13]
const c3 = [xAxisPoint[0], 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 = [xAxisPoint[0], xAxisPoint[1]]
const c3 = [xAxisPoint[0] + 18, xAxisPoint[1] - 9]
const c4 = [shape.x + 18, shape.y - 9]
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 + 18, shape.y - 9]
const c3 = [shape.x + 5, shape.y - 22]
const c4 = [shape.x - 13, shape.y - 13]
ctx.moveTo(c1[0], c1[1]).lineTo(c2[0], c2[1]).lineTo(c3[0], c3[1]).lineTo(c4[0], c4[1]).closePath()
}
})
// 注册三个面图形
echarts.graphic.registerShape('CubeLeft', CubeLeft)
echarts.graphic.registerShape('CubeRight', CubeRight)
echarts.graphic.registerShape('CubeTop', CubeTop)
