1.饼图

from pyecharts import options as opts
from pyecharts.charts import Pie
c = (Pie().add("", [['a', 10],['b', 10],['c', 10],['d', 10],['e', 10],['f',10],['g', 10]]).set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"]).set_global_opts(title_opts=opts.TitleOpts(title="Pie")).set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}")).render("pie.html")
)

饼图结果：

2.柱状图

from pyecharts import options as opts
from pyecharts.charts import Barc = (Bar().add_xaxis(['语文', '数学', '外语']).add_yaxis("2017", [67.61, 71.89, 52.34]).add_yaxis("2019", [70.25, 80.69, 64.34], category_gap="60%").set_global_opts(title_opts=opts.TitleOpts(title="2017和2019年各科平均成绩对比"),yaxis_opts=opts.AxisOpts(name='分数',name_location='middle',name_gap=30,name_textstyle_opts=opts.TextStyleOpts(font_family= 'Times New Roman',font_size=16,color='black',font_weight='bolder',)),xaxis_opts=opts.AxisOpts(name='科目',name_location='middle',name_gap=30,name_textstyle_opts=opts.TextStyleOpts(font_family= 'Times New Roman',font_size=16,color='black',font_weight='bolder',)),).render("bar.html")
)

柱状图结果：

3.折线图

import pyecharts.options as opts
from pyecharts.charts import Line
c2 = (Line().add_xaxis(["2016", "2017", "2018", "2019", "2020"]).add_yaxis("经费", [1345, 1415, 1462.5, 1565.3, 1695.9], label_opts=opts.LabelOpts(is_show=False, position="center")).set_global_opts(title_opts=opts.TitleOpts(title="2016—2020年中央财政对城乡义务教育补助经费（亿元）", pos_left="center",pos_top="20", ),legend_opts=opts.LegendOpts(is_show=False),yaxis_opts=opts.AxisOpts(name='经费(亿元)',name_location='middle',name_gap=30,name_textstyle_opts=opts.TextStyleOpts(font_family= 'Times New Roman',font_size=16,color='black',font_weight='bolder',)),xaxis_opts=opts.AxisOpts(name='年份',name_location='middle',name_gap=30,name_textstyle_opts=opts.TextStyleOpts(font_family= 'Times New Roman',font_size=16,color='black',font_weight='bolder',)),).render("Line.html")
)

折线图结果：

4.环形图

from pyecharts import options as opts
from pyecharts.charts import Pie
c = (Pie().add("", [['a', 10],['b', 10],['c', 10],['d', 10],['e', 10],['f',10],['g', 10]],radius=["40%", "50%"]).set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"]).set_global_opts(title_opts=opts.TitleOpts(title="Pie")).set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}")).render("ring.html")
)

环形图结果
