百木园我的需求：手动配置X轴、Y轴、图表标题等参数自动通过Pyecharts模块生成可视化的html数据图表，并将浏览器图表展示到UI界面上。
【阅读全文】
制作出图表后的效果展示如下：
另外，生成后的图表结果会使用 html 的形式保存下来。
导入 UI 界面相关的 PyQt5 第三方模块库。
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
若是使用PyQt5的版本是5.10.1以上，则需要单独安装一下PyQtWebEngine，说是QtWebEngineWidgets模块被新版本移除了。执行一下下面安装单独安装一下PyQtWebEngine就OK了。
pip install PyQtWebEngine
导入 Web 浏览器引擎的支持。
from PyQt5.QtWebEngineWidgets import QWebEngineView
应用其他的相关模块导入。
import sys # 应用操作库
import os
from datetime import datetime
from pyecharts.charts import * # 图表设置展示库
from pyecharts import options # 图标参数配置库
主要的代码块实现过程如下：
