eCharts bar3D一种颜色yAxis3D

Question

我尝试为每个步骤yAxis3D定义一种颜色没有成功 不管价值。我举了以下示例：https://ecomfe.github.io/echarts-examples/public/editor.html?c=bar3d-punch-card&gl=1

series: [{

        type: 'bar3D',
        data: data.map(function (item) {
            return {
                value: [item[1], item[0], item[2]],
                itemStyle: { color: 'green' } // not working
            }
        }),

        itemStyle: {
            opacity: 1,
        },

        label: {
            textStyle: {
                fontSize: 16,
                borderWidth: 1
            }
        },

        emphasis: {
            label: {

                normal: {
                    show: false,
                },
                textStyle: {
                    fontSize: 20,
                    color: '#900'
                }
            },

        }
    }]
