Echarts实战案例代码(8)：设置itemStyle渐变color属性实现柱图的伪3D效果的解决方案

重点代码

itemStyle: {
                show: true,
                color: new echarts.graphic.LinearGradient(0, 0, 1, 0, [{
                    offset: 0,
                    color: '#C70019'

                }, {
                    offset: 0.5,
                    color: '#EB354C'

                }, {
                    offset: 1,
                    color: '#C70019'

                }]),
                barBorderRadius: [20, 20, 0, 0],
                borderWidth: 0,
                borderColor: '#333',
            }

Done!
