主窗体内的pyqtgraph绘图（qt设计器）

Question

我的代码在我的主窗体中完美地绘制此代码：

                self.graphics_View_widget.clear() 
                pg.setConfigOption('background', 'k')
                h=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
                t=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
                self.graphics_View_widget.plot(h, t, pen=(0,0,255))

它在指定的位置绘制，没有任何问题

但当我想将x轴更改为字符串对象时，如下所示：

                  self.graphics_View_widget.clear()  
                  h=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
                  t=['a','b','c','d','e','f','g','h','i','j']
                  xDict=dict(enumerate(t))
                  xValue=list(xDict.keys())
                  self.graphics_View_widget= pg.GraphicsWindow()
                  bottomAxis = pg.AxisItem(orientation='bottom')
                  pp=self.graphics_View_widget.addPlot(axisItems={'bottom': bottomAxis},name='h')
                  xtickts=[xDict.items()]
                  bottomAxis.setTicks(xtickts)
                  pp.plot(xValue,h)

现在，它在一个新窗口中绘制此图表（而不是在qt设计器中指定的位置）

我的错在哪里

.py代码

      from PyQt5 import QtWidgets, uic,QtCore, QtGui
      from PyQt5.QtGui import QColor
      
      import pyqtgraph as pg
      import sys  
      
      class MainWindow(QtWidgets.QMainWindow):
      
          def __init__(self, *args, **kwargs):
              super(MainWindow, self).__init__(*args, **kwargs)
              #Load the UI Page
              uic.loadUi('teeeeest.ui', self)
              self.pushButton.clicked.connect(self.show_plot)
              
          def show_plot(self):
               ############################################ this code draws in the specified location without any problem:

                 xtickts=[xDict.items()]
                 bottomAxis.setTicks(xtickts)
                 pp.plot(xValue,h)
      
      if __name__ == '__main__':      
          app = QtWidgets.QApplication(sys.argv)
          main = MainWindow()
          main.show()
          sys.exit(app.exec_())
      

Answer 1

这是索洛廷：

1. 添加Qgraphicsview（将其命名为widget_test）

2.promote类名=GraphicsLayoutWidget-标题名=pyqtgraph

             h=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
             t=['a','b','c','d','e','f','g','h','i','j']
             xDict=dict(enumerate(t))
             xValue=list(xDict.keys())
             bottomAxis = pg.AxisItem(orientation='bottom')
             pp=self.widget_test.addPlot(axisItems={'bottom': bottomAxis},name='h')
             xtickts=[xDict.items()]
             bottomAxis.setTicks(xtickts)
             pp.plot(xValue,h)

现在在表单中有了pyqtgraph，其中包含字符串x轴

祝你好运
