前言

之前采集了我爱我家的13000多条租房信息，准备做下数据分析，也了解到Pyecharts这个可视化工具，于是上手试了一番

pyecharts 是一个用于生成 Echarts 图表的类库。Echarts 是百度开源的一个数据可视化 JS 库。用 Echarts 生成的图可视化效果非常棒，pyecharts 是为了与 Python 进行对接，方便在 Python 中直接使用数据生成图

安装

直接在cmd命令行中输入

pip install pyecharts

对于版本问题，pyecharts使用unicode编码处理所有字符串和文件，你必须在Python 2上使用unicode字符串，而Python2.x不是默认的unicode编码，所以若你用的Python2.x，则需要在开头加上

#coding=utf-8

from future import unicode_literals

示例

下面我们一起来看一下如何使用吧

柱状图

from pyecharts import Bar

def demo1():

# 普通柱状图

bar = Bar("我的第一个图表", "这里是副标题")

# 可以定义图表的主题为暗色

bar.use_theme("dark")

# 通过add() 添加数据及配置 is_more_utils 提供更多工具按钮

bar.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90], is_more_utils=True)

# bar.print_echarts_options() # 该行只为了打印配置项，方便调试时使用

# 默认bar.render() 在当前工程目录下生成 render.html 文件，再用浏览器打开即可，支持path参数

bar.render("D:\\Python\\PycharmProject\\Wiwj\\render1.html")

print("============ demo1 ============")

render1

链式调用生成柱状图数据堆叠

from pyecharts import Bar

def demo2():

# 链式调用生成柱状图数据堆叠

clothes = ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]

clothes_v1 = [3, 15, 88, 34, 66, 22]

clothes_v2 = [55, 89, 99, 15, 17, 49]

(Bar("柱状图数据堆叠示例")

.add("商家1", clothes, clothes_v1, is_stack=True, is_more_utils=True)

.add("商家2", clothes, clothes_v2, is_stack=True, is_more_utils=True)

.render("D:\\Python\\PycharmProject\\Wiwj\\render2.html"))

print("============ demo2 ============")

多图

from pyecharts import Bar, Line

from pyecharts.engine import create_default_environment

def demo3():

# 从 v0.4.0+ 开始，pyecharts 重构了渲染的内部逻辑，改善效率。推荐使用以下方式显示多个图表

bar = Bar("我的第三个图表", "这里是副标题")

bar.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90], is_more_utils=True)

line = Line("我的第三个图表", "这里是副标题")

line.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90], is_more_utils=True)

# 为渲染创建一个默认配置环境: 'html', 'svg', 'png', 'jpeg', 'gif' or 'pdf'

# 这里使用同一个引擎对象，减少了部分重复操作，速度有所提高

env = create_default_environment("html")

env.render_chart_to_file(bar, path='bar.html')

env.render_chart_to_file(line, path='line.html')

print("============ demo3 ============")

numpy，pandas示例

import pandas as pd

import numpy as np

from pyecharts import Bar

def demo4():

# numpy pandas示例

title = "bar chart"

index = pd.date_range('3/8/2017', periods=6, freq='M')

df1 = pd.DataFrame(np.random.randn(6), index=index)

df2 = pd.DataFrame(np.random.randn(6), index=index)

dtvalue1 = [i[0] for i in df1.values]

dtvalue2 = [i[0] for i in df2.values]

_index = [i for i in df1.index.format()]

bar = Bar(title, "Profit and loss situation")

bar.add('profit', _index, dtvalue1)

bar.add('loss', _index, dtvalue2)

bar.render("D:\\Python\\PycharmProject\\Wiwj\\render4.html")

print("============ demo4 ============")

带有最大最小以及平均线的柱形图

from pyecharts import Bar

def demo5():

# 带有最大最小以及平均线的柱形图

month = ["{}月".format(i) for i in range(1, 13)]

data1 = [2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6, 162.2, 32.6, 20.0, 6.4, 3.3]

bar = Bar("柱状示例图")

bar.add("蒸发量", month, data1, mark_line=["average"], mark_point=["max", "min"])

bar.add("降水量", month, data2, mark_line=["average"], mark_point=["max", "min"])

bar.render("D:\\Python\\PycharmProject\\Wiwj\\render5.html")

print("============ demo5 ============")

饼状图

from pyecharts import Pie

def demo6():

# 饼状图

food = ["手抓饼", "手抓饼加鸡蛋", "手抓饼加火腿", "手抓饼加培根", "手抓饼加里脊", "手抓饼加全部"]

shop1 = [5, 6, 7, 9, 8, 12]

shop2 = [5, 5.5, 7, 7, 7, 10]

pie = Pie("小摊手抓饼价格", title_pos="center", width=900)

pie.add("第一家店", food, shop1, center=[25, 50], is_random=True, radius=[30, 75], rosetype='radius')

pie.add("第二家店", food, shop2, center=[75, 50], is_random=True, radius=[30, 75], rosetype='area',

is_legend_show=False, is_label_show=True)

pie.render("D:\\Python\\PycharmProject\\Wiwj\\render6.html")

print("============ demo6 ============")

折线图 + 柱状图

from pyecharts import Bar, Line, Overlap

def demo7():

# 折线图 + 柱状图

month = ["{}月".format(i) for i in range(7, 13)]

salary = [4300, 3300, 3850, 3880, 3680, 3880]

spending = [3300, 2600, 2200, 2300, 2840, 3000]

bar = Bar('月薪-开销示例')

bar.add("月薪", month, salary)

line = Line()

line.add("开销", month, spending)

# 创建一个交叠图

overlap = Overlap()

# 添加柱形图

overlap.add(bar)

overlap.add(line)

overlap.render("D:\\Python\\PycharmProject\\Wiwj\\render7.html")
