我正在使用 picot GUI 應用程序來顯示一些圖形和圖表，我嘗試使用 pyqtgraph 來實現，但它不適用于日期或時間，所以我切換到 matplotlib它工作完美，但結果顯示在同一個窗口中，我無法返回主窗口我正在尋找一種在另一個窗口中顯示相同結果的方法，因為我嘗試使用像本例這樣的小部件來完成此操作https://github.com/swharden/Python-GUI-examples/tree/master/2016-07 -30_qt_matplotlib_sine_scroll，在ui內部但有很多問題我嘗試在第二個窗口 pyqt5 中使用這個例子 matplotlib 它工作完美并且它顯示另一個窗口但它是空的這是我的用戶界面<?xml version="1.0" encoding="UTF-8"?><ui version="4.0"> <class>MainWindow</class> <widget class="QMainWindow" name="MainWindow"> <property name="geometry"> <rect> <x>0</x> <y>0</y> <width>800</width> <height>600</height> </rect> </property> <property name="windowTitle"> <string>MainWindow</string> </property> <widget class="QWidget" name="centralwidget"> <widget class="QPushButton" name="pushButton_113"> <property name="geometry"> <rect> <x>610</x> <y>90</y> <width>161</width> <height>41</height> </rect> </property> <property name="text"> <string>Recherche</string> </property> </widget> <widget class="QDateEdit" name="dateEdit_20"> <property name="geometry"> <rect> <x>340</x> <y>90</y> <width>251</width> <height>41</height> </rect> </property> <property name="dateTime"> <datetime> <hour>0</hour> <minute>0</minute> <second>0</second> <year>2020</year> <month>1</month> <day>1</day> </datetime> </property> <property name="calendarPopup"> <bool>true</bool> </property> </widget> <widget class="QDateEdit" name="dateEdit_19"> <property name="geometry"> <rect> <x>40</x> <y>90</y> <width>271</width> <height>41</height> </rect> </property> <property name="dateTime"> <datetime> <hour>0</hour> <minute>0</minute> <second>0</second> <year>2020</year> <month>1</month> <day>1</day> </datetime> </property>

for row in rows:
