提升窗口部件步骤：
1）qt Designer--新建对话框QDialog--将2个QWidget控件拖到对话框内--
将2个对象命名为graph1,graph2
2）选择graph1--右键--提升为--基类名称：QWidget
提升的类名称：GraphicsLayoutWidget#类名称包含在头文件中
头文件：pyqtgraph.h#固定
--输入完成点添加--点提升--退出
3）选择graph2--右键--提升为(上面）--点开小三角：显示GraphicsLayoutWidget
--点击GraphicsLayoutWidget--自动退出--完成
说明：上面的提升的类名称除非你明白意思，否则按上面的设置，单都必须在头文件中。
