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

python">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

python"># 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

python">from pyecharts.charts import Bar
from pyecharts.faker import Faker
from pyecharts import options as opts
# 绘制图表
bar = (Bar().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)
)
bar.render_notebook()

3、折线图

python">from pyecharts.charts import Line
from pyecharts.faker import Faker
from pyecharts import options as opts
from pyecharts.globals import ThemeType
x_data = Faker.week
types = Faker.choose()
line = (Line(init_opts=opts.InitOpts(theme=ThemeType.DARK)).add_xaxis(x_data).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

python">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

python">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'))
)
# 渲染图表
sc.render_notebook()

5、箱图

python">from pyecharts.charts import Boxplot
from pyecharts.faker import Faker
from pyecharts import options as opts
from pyecharts.globals import ThemeType
from random import randint
box =  Boxplot()
box = (box.add_xaxis(Faker.choose()).add_yaxis('商家A',box.prepare_data([[randint(0,100) for i in range(100)],[randint(10,100) for i in range(100)],[randint(20,100) for i in range(100)],[randint(30,100) for i in range(100)],[randint(40,100) for i in range(100)],[randint(60,100) for i in range(100)],[randint(80,100) for i in range(100)],])).add_yaxis('商家B',box.prepare_data([[randint(0,100) for i in range(100)],[randint(10,100) for i in range(100)],[randint(20,100) for i in range(100)],[randint(30,100) for i in range(100)],[randint(40,100) for i in range(100)],[randint(60,100) for i in range(100)],[randint(80,100) for i in range(100)],]))
)
# 渲染图表
box.render_notebook()

6、饼图

python">from pyecharts.charts import Pie
from pyecharts.faker import Faker
from pyecharts import options as opts
from pyecharts.globals import ThemeType
from random import randint
pie = (Pie().add('',data_pair=[i for i in zip(Faker.choose(),Faker.values())],label_opts=opts.LabelOpts(formatter='{b}:{c}')).set_global_opts(legend_opts=opts.LegendOpts(textstyle_opts=opts.TextStyleOpts(color='white'))).set_series_opts(label_opts=opts.LabelOpts(formatter='{b}:{d}'))
)
# 渲染图表
pie.render_notebook()

空心饼图

python">pie = (Pie().add('',data_pair=[i for i in zip(Faker.choose(),Faker.values())],radius=['50%','70%'] ).set_global_opts(legend_opts=opts.LegendOpts(textstyle_opts=opts.TextStyleOpts(color='white'))).set_series_opts(label_opts=opts.LabelOpts(formatter='{b}:{d}'))

from random import randint
# 生成图表中的具体数据
value = [[i, j, randint(-20, 40)] for i in range(24) for j in range(7)]
# 绘制图表
hp = (HeatMap().add_xaxis(Faker.clock).add_yaxis('温度',Faker.week,value).set_global_opts(visualmap_opts=opts.VisualMapOpts(min_=-10,max_=50))
)
# 渲染图表
hp.render_notebook()
