Python----数据可视化（pyecharts二：绘图一：条形图，直方图，折线图，散点图，箱图，饼图，热力图）

1、条形图

from pyecharts.charts import Bar
from pyecharts.faker import Faker
from pyecharts import options as opts
# 绘制柱状图
bar = (
    Bar() # 创建柱状图
    .add_yaxis("商家A", Faker.values(),color=Faker.rand_color()) # 添加数据
    .add_yaxis("商家B", Faker.values(),color=Faker.rand_color())
    .add_xaxis(Faker.choose()) # 添加x轴数据
    .set_global_opts(title_opts=opts.TitleOpts(title="柱状图", subtitle="副标题")) # 设置标题
)
# 渲染图表
bar.render_notebook()

设置标记线 

# 设置标记线
bar = (
    Bar() # 创建柱状图
    .add_yaxis("商家A", Faker.values(),color=Faker.rand_color()) # 添加数据
    .add_yaxis("商家B", Faker.values(),color=Faker.rand_color())
    .add_xaxis(Faker.choose()) # 添加x轴数据
    .set_global_opts(title_opts=opts.TitleOpts(title="柱状图", subtitle="副标题")) # 设置标题
    .set_series_opts(markline_opts=opts.MarkLineOpts(
        data=[
            # opts.MarkLineItem(type_="average", name="平均值")
            opts.MarkLineItem(y=80,name='合格线')
              ]
    )) # 设置标记线
)
# 渲染图表
bar.render_notebook()

设置堆叠 

2、直方图

    .add_xaxis(Faker.choose())
    .add_yaxis("商家A", Faker.values(),gap='0%')
    .add_yaxis("商家B", Faker.values(),gap='0%')
    .set_global_opts(
        title_opts=opts.TitleOpts(title="直方图",title_textstyle_opts=opts.TextStyleOpts(color='white')), # 标题文字颜色
        legend_opts=opts.LegendOpts(textstyle_opts=opts.TextStyleOpts(color='white')), # 图例文字颜色

    .add_yaxis(types[0],Faker.values(),stack="总量")
    .add_yaxis(types[1],Faker.values(),stack="总量")
    .add_yaxis(types[2],Faker.values(),stack="总量")
    .add_yaxis(types[3],Faker.values(),stack="总量")
    .add_yaxis(types[4],Faker.values(),stack="总量")
    .add_yaxis(types[5],Faker.values(),stack="总量")
    .add_yaxis(types[6],Faker.values(),stack="总量")
)
line.render_notebook()

面积堆叠 

line = (
    Line(init_opts=opts.InitOpts(theme=ThemeType.DARK))  # 设置主题
    .add_xaxis(Faker.choose())
    .add_yaxis("商家A", Faker.values(),stack='总量')
    .add_yaxis("商家B", Faker.values(),stack='总量')
    .add_yaxis("商家C", Faker.values(),stack='总量')
    .add_yaxis("商家D", Faker.values(),stack='总量')
)
line.set_series_opts(
    areastyle_opts=opts.AreaStyleOpts(opacity=0.8),  # 增加面积图的显示
    label_opts=opts.LabelOpts(is_show=False),        # 不显示标签
)
line.set_global_opts(
    title_opts=opts.TitleOpts(title="Line-面积图堆叠"),  # 设置标题
    xaxis_opts=opts.AxisOpts(boundary_gap=False),    # 从x轴原点开始绘制
    tooltip_opts=opts.TooltipOpts(trigger="axis"),  # 设置鼠标悬停时的提示
)
# 渲染图表
line.render_notebook()

4、散点图 

from pyecharts.charts import Scatter
from pyecharts.faker import Faker
from pyecharts import options as opts
from pyecharts.globals import ThemeType
sc = (
    Scatter() # 初始化散点图
    .add_xaxis(Faker.choose())  # x轴数据
    .add_yaxis('',Faker.values())  # y轴数据
    .set_global_opts(
        visualmap_opts=opts.VisualMapOpts(type_='size')
    )
