4.主要代码段：

				center:['50%', '60%'],
                //radius: getValueFromJson(data, 'name').length > 6 ?  ['40%', '84px'] :  ['46%','90px'],
				 radius: '55%',
                avoidLabelOverlap: true,
                minAngle: 5,
                label: {
                	align: 'left',

                        show: show,
						lineHeight:30,

                            let text = Math.round(v.percent)+'%' + '' + v.name
                            if(text.length <= 8)
