pyecharts在数据可视化中的应用
**
使用pyecharts进行数据可视化分析
**
1. 树图绘制
1、使用以下JSON数据绘制树图、矩形树图。代码片
from pyecharts import options as opts
from pyecharts.charts import Tree
from pyecharts.charts import TreeMap
data = [{
"name": "flare",
"children": [
{
"name": "flex",
"children": [
{"name": "FlareVis", "value": 4116}
]
},
{
"name": "scale",
"children": [
{"name": "IScaleMap", "value": 2105},
{"name": "LinearScale", "value": 1316},
{"name": "LogScale", "value": 3151},
{"name": "OrdinalScale", "value": 3770},
{"name": "QuantileScale", "value": 2435},
{"name": "QuantitativeScale", "value": 4839},
{"name": "RootScale", "value": 1756},
{"name": "Scale", "value": 4268},
{"name": "ScaleType", "value": 1821},
{"name": "TimeScale", "value": 5833}
]
},
{
"name": "display",
"children": [
{"name": "DirtySprite", "value": 8833}
]
}
]
}]
b = (
Tree()
.add("", data)
.set_global_opts(title_opts=opts.TitleOpts(title="使用以下JSON数据绘制树图", subtitle="xuxiaozhen"))
.render("树形图.html")
)
c = (
TreeMap()
.add("数据", data,)
.set_global_opts(title_opts=opts.TitleOpts(title="使用以下JSON数据绘制矩形树图", subtitle="xuxiaozhen"))
.render("矩形树图.html")
)
2. 散点图矩阵绘制
2、绘制鸢尾花数据的相关性矩阵。代码片
from matplotlib import pyplot as plt
import pandas as pd
import seaborn as sns
file = pd.read_csv("/Users/*****/Downloads/iris.csv")
sns.pairplot(file,hue="Species")
plt.show()
3. 地理热力图、地图上标注点的绘制
3、在地图上用圆点标出各省的销售额数据。代码片
from pyecharts import options as opts
from pyecharts.charts import Map
import random
province = ['广东', '湖北', '湖南', '四川', '重庆', '黑龙江', '浙江', '山西', '河北', '安徽', '河南', '山东', '西藏']
c = (
Map()
.add("销售额", [(i, random.randint(50, 150)) for i in province], "china")
.set_global_opts(title_opts=opts.TitleOpts(title="各省的销售额数据", subtitle="xuxiaozhen"))
.render("地图.html")
)
4、绘制地理热点图展示某连锁企业在湖北省各城市的门店数。代码片
from pyecharts import options as opts
from pyecharts.charts import Geo
from pyecharts.globals import ChartType
import random
province = ['武汉', '十堰', '鄂州', '宜昌', '荆州', '孝感', '黄石', '咸宁', '仙桃']
c = (
Geo()
.add_schema(maptype="湖北")
.add("门店数", [(i, random.randint(50, 150)) for i in province],type_=ChartType.HEATMAP)
.set_series_opts(label_opts=opts.LabelOpts(is_show=False))
.set_global_opts(
title_opts=opts.TitleOpts(title="某连锁企业在湖北省各城市的门店数", subtitle="xuxiaozhen"),
visualmap_opts=opts.VisualMapOpts()
)
.render("地理热点图.html")
)
热力图关键：type_=ChartType.HEATMAP
4. 词云图绘制
5、绘制词云图。代码片
import pyecharts.options as opts
from pyecharts.charts import WordCloud
import pandas as pd
data = pd.read_csv("/Users/****/Downloads/word_data.csv")
data2 = data.groupby(by=['category']).agg({'views':sum}).reset_index().values
wordcloud = (
WordCloud()
.add("", data2, word_size_range=[8,80])
.set_global_opts(
title_opts=opts.TitleOpts(
title="绘制词云图", title_textstyle_opts=opts.TextStyleOpts(font_size=24), subtitle="xuxiaozhen"),
tooltip_opts=opts.TooltipOpts(is_show=True)
)
.render("词云图.html")
)
5. 主题河流图绘制
6、绘制主题河流图。代码片
