plotting 2d and 3d using pyqt5 and pyqtgraph and GLSurfacePlotItem
#1
Hi, I am trying to plot two graphs in one window, one 2d and another 3d. I am able to get the 2d plot to work but when I try to plot in 3d using GLSurfacePlotItem I get the following error:
Error:
AttributeError: 'GLViewWidget' object has no attribute 'GLSurfacePlotItem'
the 3d plot widget was promoted with class name:GLViewWidget, headerfile: pyqtgraph.opengl.h. how can I plot in 3d using pyqtgraph? I have the code that I want to run working, but it isn't inserted in a pyqt5 window.

this is the code I am using(.py)
from PyQt5 import QtWidgets, uic
#import pyqtgraph.opengl as gl
import sys
import numpy as np

class MainWindow(QtWidgets.QMainWindow):

    def __init__(self, *args, **kwargs):
        super(MainWindow, self).__init__(*args, **kwargs)

        #Load the UI Page
        uic.loadUi('help.ui', self)

        # Set up plots axes
        self.graphWidget_2D.setLabel('left', 'Pixels')
        self.graphWidget_2D.setLabel('bottom', 'Time', 'days')
        
        self.plot()

    def plot(self):
        Z = np.ones((10, 10))
        self.graphWidget_3D.GLSurfacePlotItem(z=Z, shader='shaded', color=(0.5, 0.5, 1, 1))
        a = np.random.randn(150)
        b = np.random.randn(150)
        self.graphWidget_2D.plot(np.sort(a), np.sort(b))


def main():
    app = QtWidgets.QApplication(sys.argv)
    main = MainWindow()
    main.show()
    sys.exit(app.exec_())

if __name__ == '__main__':         
    main()
and this is the ui file:

never mind, I solved it

class MainWindow(QtWidgets.QMainWindow):

    def __init__(self, *args, **kwargs):
        super(MainWindow, self).__init__(*args, **kwargs)

        #Load the UI Page
        uic.loadUi('MainWindow.ui', self)

        self.setup2d_graphs()
        self.setup3d_inv()
        
        self.plot([1,2,3,4,5,6,7,8,9,10], [30,32,34,32,33,31,29,32,35,45])

    def setup3d_inv(self):
        self.graphWidget.setCameraPosition(distance=50)
        ## Add a grid to the view
        g = gl.GLGridItem()
        g.scale(1, 1, 1)
        g.setDepthValue(100)  # draw grid after surfaces since they may be translucent
        self.graphWidget.addItem(g)
    
    def plot(self, hour, temperature):
        Z = np.ones((2, 2))
        p1 = gl.GLSurfacePlotItem(z=Z, shader='shaded', color=(0.5, 0.5, 1, 1))
        self.graphWidget.addItem(p1)
        
        # self.graphWidget.plot(hour, temperature)
        a = np.random.randn(150)
        b = np.random.randn(150)
        self.graphWidget_2D.plot          (np.sort(a), np.sort(b))


def main():
    app = QtWidgets.QApplication(sys.argv)
    main = MainWindow()
    main.show()
    sys.exit(app.exec_())

if __name__ == '__main__':         
    main()
