之前介绍过用pyecharts显示地图。下面先生成显示中国各省人口地图的网页。
代码语言：javascript复制from pyecharts import options as opts
from pyecharts.charts import Map, Page
from pyecharts.faker import Collector, Faker
def readData(path):
populations = list()
with open(path,"rt",encoding="utf8") as f:#读取中文文本文件
line = f.readline()
while line:
a = line[:-1].split("t")
populations.append([a[0],int(a[1])])
line = f.readline()
return populations
C = Collector()
@C.funcs
def map_visualmap() -> Map:
c = (
Map()
.add("中华人民共和国各省人口数(第6次人口普查)", populations, "china")
.set_global_opts(
title_opts=opts.TitleOpts(title="pyecharts 嵌入 PyQt5 DEMO"),
visualmap_opts=opts.VisualMapOpts(max_=max_),
)
)
return c
populations = readData("人口.txt")#从国家统计局官网下载
max_ = max(x[1] for x in populations)
Page().add(*[fn() for fn, _ in C.charts]).render("ChinaPopulationMap.html")使用PyQt5的浏览器引擎控件即可加载网页到GUI界面中，效果如下:
源码：
代码语言：javascript复制from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication,QWidget,QHBoxLayout,QFrame
from PyQt5.QtWebEngineWidgets import QWebEngineView
import sys
class UI(QWidget):
def __init__(self):
super().__init__()
self.initUI()
self.mainLayout()
def initUI(self):
self.setWindowTitle("中国各省人口")
def mainLayout(self):
self.mainhboxLayout = QHBoxLayout(self)
self.frame = QFrame(self)
self.mainhboxLayout.addWidget(self.frame)
self.hboxLayout = QHBoxLayout(self.frame)
#网页嵌入PyQt5
self.myHtml = QWebEngineView()##浏览器引擎控件
#url = "http://www.baidu.com"
#打开本地html文件#使用绝对地址定位，在地址前面加上 file:/// ，将地址的 改为/
self.myHtml.load(QUrl("file:///E:/Python36/MyPythonFiles/pyecharts/ChinaPopulationMap.html"))
self.hboxLayout.addWidget(self.myHtml)
self.setLayout(self.mainhboxLayout)
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = UI()
ex.show()
sys.exit(app.exec_())
