安裝和查看版本

安裝：

換源爲清華源。

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyecharts

查看版本：

import pyecharts
print(pyecharts.__version__)

導包

本文使用的版本是1.7.1

最常見的問題是直接導入模塊失敗，如：

from pyecharts import Bar

因爲擴展模塊的原因，需要這麼寫才能導入

from pyecharts.charts import Bar

繪製柱形圖

#創建圖表並設置主題
bar = Bar(init_opts=opts.InitOpts(theme=ThemeType.LIGHT))
#添加x值，x是一個列表
bar.add_xaxis(name)
#添加y值，y是一個列表
bar.add_yaxis('購買人數',count)
#設置主標題、副標題
bar.set_global_opts(title_opts=opts.TitleOpts(title="Dior999色號分佈", subtitle="數據來源：京東"))
#設置生成html文件
bar.render('bar.html')
