【Python可视化】超详细Pyecharts 1.x教程，让你

2020-02-19  本文已影响0人  AwesomeTang

前言

pyecharts 是一个用于生成 Echarts 图表的Python库。Echarts是百度开源的一个数据可视化 JS 库，可以生成一些非常酷炫的图表。

AQI指数
Pyecharts在1.x版本之后迎来重大更新，与老版本（0.5X）已是两个完全不同的版本，所以很多小伙伴在使用Pyecharts出现了类似'pyecharts' has no attribute 'xxx'的报错，那是因为你安装了1.x的版本却使用了0.5x的调用方法。

本文将会介绍Pyecharts1.x版本的使用方法，本文所有语句均基于v1.6.2，通过以下语句查询使用pyecharts版本：

import pyecharts

print(pyecharts.__version__)

基本使用

链式调用

pyecharts在v1.x之后支持链式调用，具体语句如下：

from pyecharts.charts import Bar
from pyecharts import options as opts

# 示例数据
cate = ['Apple', 'Huawei', 'Xiaomi', 'Oppo', 'Vivo', 'Meizu']
data1 = [123, 153, 89, 107, 98, 23]
data2 = [56, 77, 93, 68, 45, 67]

# 1.x版本支持链式调用
bar = (Bar()
       .add_xaxis(cate)
       .add_yaxis('电商渠道', data1)
       .add_yaxis('门店', data2)
       .set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
      )
# 在jupyter notebook总渲染
bar.render_notebook()

单独调用

不习惯链式调用的开发者依旧可以单独调用方法。

# 单独调用
bar = Bar()
bar.add_xaxis(cate)
bar.add_yaxis('电商渠道', data1)
bar.add_yaxis('门店', data2)
bar.set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
bar.render_notebook()

全局配置

可以通过全局配置(.set_global_opts():)控制以下区域



使用示例如下： 
"""
全局配置项使用示例：
1. 标题 & 副标题
2. 关闭图例
3. 显示工具箱
"""
bar = (Bar()
       .add_xaxis(cate)
       .add_yaxis('电商渠道', data1)
       .add_yaxis('门店', data2)
       .set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"),
                        toolbox_opts=opts.ToolboxOpts(),
                        legend_opts=opts.LegendOpts(is_show=False))
      )

bar.render_notebook()

系列配置

可以通过系列配置（.set_series_opts()）控制图表中的文本，线样式，标记等，使用示例如下：

"""
系列配置项使用示例：
1. 不显示数值
2. 标记每个系列的最大值
"""
bar = (Bar()
       .add_xaxis(cate)
       .add_yaxis('电商渠道', data1)
       .add_yaxis('门店', data2)
       .set_series_opts(label_opts=opts.LabelOpts(is_show=False),
                        markpoint_opts=opts.MarkPointOpts(data=[opts.MarkPointItem(type_="max", name="最大值"),]))
       .set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
      )

bar.render_notebook()
