唉，用pyecharts画旭日图太依赖这样的数据结构了，或许我们大多数人都很少用到这样的结构，在实用中我们通常用excel存储数据，类似这样

graph

要改为合适的数据格式，可能需要编程做数据处理了，这里提供一种思路，可以筛选出第一级某标签对应的数据，再添加属性，再筛选二级标题下的数据，再添加属性，以此类推。这里我们主要以画图为主，先用json数据处理。

开始画图

1
2
3
4
5
6
sun = (Sunburst()
       .add("", data_pair=data)

)
sun.render("旭日图.html")
os.system("旭日图.html")

添加元素

1
2
3
4
5
6
7
sun = (Sunburst(init_opts=opts.InitOpts(width="900px", height="600px"))
       .add("", data_pair=data,
            highlight_policy="ancestor",  # 高亮相关的扇形块
            radius=[0, "95%"],  # 数组的第一项是内半径，第二项是外半径。
            sort_="null",  # 排序方式)
       .set_global_opts(title_opts=opts.TitleOpts(title="饮料风味旭日图"))
)

sort_可选’descendant’：高亮该扇形块和后代元素，其他元素将被淡化；

​ ‘ancestor’：高亮该扇形块和祖先元素；

​ ‘self’：只高亮自身；

​ ‘none’：不会淡化其他元素。

设置层级

levels=[
    {},
    {
        "r0": "15%",  # 第一层内半径
        "r": "35%",  # 第一层外半径，100%是到达画框边界
        "itemStyle": {"borderWidth": 2},  # 边框宽度
        "label": {"rotate": 'tangential'},  # 标签旋转角度，这里表示全按切线方向，一定还有其他选项，目前没找全。radial-径向；tangential-切向
    },
    {"r0": "35%", "r": "70%", "label": {"align": "right"}},  # 对齐方式
    {
        "r0": "70%",
        "r": "72%",
        "label": {"position": "outside", "padding": 3, "silent": False},  # padding 内边距;不需要使用Fundebug为True
        "itemStyle": {"borderWidth": 3},
    },
]

网上没有搜到详细的教程，感觉可能是CSS代码，可能触及到知识的边缘了。

大功告成！
