使用python的pyecharts库绘制多选项卡折线图示例

pyecharts介绍

Pyecharts是一个用于生成Echarts图表的类库，可以与Python进行对接，方便在Python中直接使用数据生成图。

Echarts是百度开源的一个数据可视化JS库，生成的图可视化效果非常棒，凭借着良好的交互性，精巧的图表设计，得到了众多开发者的认可。

Pyecharts v1停止对Python 2.7及Python 3.4~3.5版本的支持和维护，仅支持Python 3.6+。

环境

• Ubuntu 18.04 LTS
• python 3.8.10
• pyecharts-1.9.1

安装环境

pip install pyecharts

条形图

• 源码：

# -*- coding: utf-8 -*-
from pyecharts import options as opts
from pyecharts.charts import Bar, Page
#from impala.dbapi import connect

bar=Bar()
bar.add_xaxis(["数学", "语文", "英语", "政治", "历史", "地理", "物理", "化学", "生物"])
bar.add_yaxis("班级A", [134, 125, 127, 89, 95, 87, 85, 88, 89])
bar.add_yaxis("班级B", [131, 128, 129, 87, 92, 88, 86, 85, 92])
bar.set_global_opts(title_opts=opts.TitleOpts(title="学生考试成绩比较分析", subtitle="2019年班级A和班级B期末考试"),
)

#第一次渲染时调用load_javasrcript文件
bar.load_javascript()

#展示数据可视化图表
#bar.render_notebook()
bar.render('test.html')
