pyecharts-动态可视化(8)-饼状图 （基础-富文本-共用-rosetype-内外饼图）

代码非常详细 pyecharts可视化 饼状图~

饼状图基本版（1 of 4）

引入

from pyecharts.charts import Pie 后面都会用到这个包
Pie()饼状图

from pyecharts import options as opts
from pyecharts.charts import Pie
from pyecharts.faker import Faker
c = (Pie().add("", [list(z) for z in zip(Faker.choose(), Faker.values())]).set_global_opts(title_opts=opts.TitleOpts(title="Pie-基本示例")).set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}")).render("pie_base.html")
)

饼状图设置样式+标签设置（2 of 4）

样式设置（位置、颜色）

①位置设置
.add(center=["35%", "50%"]
②颜色设置
.set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"])
可以自主进行颜色设置，可是有个问题就是，自己设置的颜色其实通常不如默认设置。

标签设置formatter

label_opts=opts.LabelOpts(formatter="{a|{a}}{abg|}\n{hr|}\n {b|{b}: }{c} {per|{d}%} )
标签内容格式器，支持字符串模板和回调函数两种形式，字符串模板与回调函数返回的字符串均支持用 \n 换行。

字符串模板 模板变量有：
{a}：系列名。
{b}：数据名。
{c}：数据值。
{d}：百分比。
{@xxx}：数据中名为’xxx’的维度的值，如{@product}表示名为’product’的维度的值。 {@[n]}：数据中维度n的值，如{@[3]} 表示维度 3 的值，从 0 开始计数。

{per|{a}} 用{}框起来，前面的第一个per是样式设置，后面一个a代表系列名称，相当于说per样式修饰了竖线后面部分的样式

结合例子，去理解formatter就好~

from pyecharts import options as opts
from pyecharts.charts import Pie
c = (Pie().add("这个是系列名称",[list(z) for z in zip(['衬衫', '毛衣', '领带', '裤子', '风衣', '高跟鞋', '袜子'], [65, 35, 125, 111, 34, 59, 131])],radius=["40%", "55%"],center=["35%", "50%"],# 位置设置label_opts=opts.LabelOpts(position="outside",formatter="{a|{a}}{abg|}\n{hr|}\n {b|{b}: }{c} {per|{d}%} ",background_color="#eee",border_color="#aaa",border_width=1,border_radius=4,rich={"a": {"color": "#999", "lineHeight": 22, "align": "center"},"abg": {"backgroundColor": "#e3e3e3", #上面的背景设置"width": "100%","align": "right","height": 22,"borderRadius": [4, 4, 0, 0],},"hr": { #相当于中间的分割线样式设置"borderColor": "#aaa","width": "100%","borderWidth": 0.5,"height": 0,},"b": {"fontSize": 16, "lineHeight": 33},#名称文字样式"per": { # 百分数的字体样式设置"color": "#eee","backgroundColor": "#334455","padding": [2, 4], #[高，宽]设置，那个背景矩形"borderRadius": 2, #圆角设置},},),)# .set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"]) # 颜色设置.set_global_opts(title_opts=opts.TitleOpts(title="Pie-富文本示例"),legend_opts=opts.LegendOpts(pos_left="65%", orient="vertical"),).render("pie_rich_label.html")
)

饼状图（共用，多个图）（3 of 4）

适用于某个类别同时存在于多个交叉类别

from pyecharts import options as opts
from pyecharts.charts import Pie
from pyecharts.commons.utils import JsCodefn = """function(params) {if(params.name == '其他')return '\\n\\n\\n' + params.name + ' : ' + params.value + '%';return params.name + ' : ' + params.value + '%';}"""def new_label_opts():return opts.LabelOpts(formatter=JsCode(fn), position="center")
c = (Pie().add("",[list(z) for z in zip(["剧情", "其他"], [25, 75])],center=["20%", "30%"],radius=[60, 80],label_opts=new_label_opts(),).add("",[list(z) for z in zip(["奇幻", "其他"], [24, 76])],center=["55%", "30%"],radius=[60, 80],label_opts=new_label_opts(),).add("",[list(z) for z in zip(["爱情", "其他"], [14, 86])],center=["20%", "70%"],radius=[60, 80],label_opts=new_label_opts(),).add("",[list(z) for z in zip(["惊悚", "其他"], [11, 89])],center=["55%", "70%"],radius=[60, 80],label_opts=new_label_opts(),).set_global_opts(title_opts=opts.TitleOpts(title="Pie-多饼图基本示例"),legend_opts=opts.LegendOpts(type_="scroll", pos_top="20%", pos_left="80%", orient="vertical"),).render("mutiple_pie.html")
)
