## 场景 ##

官方花瓣图实例：

官方示例效果：

需要修改成的效果

需要将图形旁边的分类一等修改成具体业务相关 信息比如正极车间，加上需要显示的数量等。

## 实现 ##

SpringBoot+AntV实现饼状图中的花瓣图：

参照上面的引进AunV的过程。

找到设置图表的js代码中：

chart.intervalStack().position('value').color('type').shape('platelet')
                    .label('type', {
                        formatter: function formatter(value, type) {
                            return type.point.type + ': ' + type.point.value;
                        }
                    });

其中type是数据源中的属性，type.point.type就是获取数据源中的type属性，type.point.value就是获取数据源中的value属性。

数据源参照如下:

var data = [{
                        type: names1[0],
                        value:values1[0],
                        percent:values1[0]/(values1[0]+values1[1]+values1[2]+values1[3])
                    }, {
                        type: names1[1],
                        value:values1[1],
                        percent:values1[1]/(values1[0]+values1[1]+values1[2]+values1[3])
                    }, {
                        type: names1[2],
                        value:values1[2],
                        percent:values1[2]/(values1[0]+values1[1]+values1[2]+values1[3])
                    }, {
                        type: names1[3],
                        value:values1[3],
                        percent:values1[3]/(values1[0]+values1[1]+values1[2]+values1[3])
                    }
                    ];
