                  magicType: {show: true, type: ['line', 'bar', 'stack', 'tiled']},
                  restore: {show: true},
                  saveAsImage: {show: true}
              }
          },

                  type:'line',
                  smooth:true,

                      }
                  },
                  areaStyle: {
                      normal: {
                          color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{
                              offset: 0,
                              color: 'rgb(255, 158, 68)'
