        },

        // top: '5%',

        // left: 'center'

// },

        {

                type: 'image',  // 插入圆环中间的图片

                        image: require('./echartBg.png'), // 本地图片要用require引入

                        width: 76, // 设置图片大小

                        height: 76

                },

                // 设置图片位置

                left: 'center',

                top: '20%'

        },

        { //环形图中间添加文字

                type: 'text', //通过不同top值可以设置上下显示

                left: 'center',

                top: '38%',

                style: {

                        text: '85%',

                        textAlign: 'center',

                        fontSize: 16,

                        fontFamily: "Microsoft YaHei"

                }

        },

        // 写了两个文字插入是因为业务要求两行不一样样式的字

        { //环形图中间添加文字  

                type: 'text', //通过不同top值可以设置上下显示

                left: 'center',
