   	        type: 'bar3D',
               data: data.map(function (item) {
                   return {
                       value: [item[1], item[0], item[2]],
                   }
               }),
               shading: 'lambert',
       
               label: {
                   textStyle: {
                       fontSize: 16,
                       borderWidth: 1
                   }
               },
       
               emphasis: {
                   label: {
                       textStyle: {
                           fontSize: 20,
                           color: '#900'
                       }
                   },
                   itemStyle: {
                       color: '#900'
                   }
               }
           }
       ]
   }
   现在的情况是:
   1.左下角的坐标是正方体的原点坐标,从这个原点开始往xyz轴方向5cm就是它的长宽高(它的长宽高就是5cm);例如左下角的坐标是(1,1,1),那么它右上角的坐标就是(6,6,6).而且是悬浮在空中
   2.现在的要求是悬浮在柱体上显示的是可以是它的坐标(1,1,1),但是要求视觉看上是个正方体,且这样不同坐标同样边长的正方体是多个,视觉上它的长宽高要和xyz轴的刻度一致;例如左下角的坐标是(1,1,1),那么它剩余的坐标是(1,6,1),(1,6,6),(6,1,1),(6,6,1),(6,6,6)...
   3.虽然前行修改了xy轴的刻度值,但是刻度值之间的距离不对,例如x轴数字是0,6,7,8...,但是刻度之间的距离是一样的
   4.z轴如果type不是value的话就不会让柱体浮在空中,随之而来的是不能控制显示的数字
