Hi, Kenneth,
Thanks so much for your kind reply.
My python version is Python 3.7.2, I installed it via via Homebrew.
PyQt5 is installed for PyQtGraph. I just install the PyQtGraph by this
command: pip install pyqtgraph. I also installed OpenGL for 3D display.
Here, I will use a simple example to show the problem.
code:
from pyqtgraph.Qt import QtCore, QtGui
import pyqtgraph.opengl as gl
import numpy as np
from math import *
import time
app = QtGui.QApplication([])
w = gl.GLViewWidget()
w.opts['distance'] = 200
w.show()
w.setWindowTitle('Quadcopter Simulation')
## create three grids, add each to the view
xgrid = gl.GLGridItem()
ygrid = gl.GLGridItem()
zgrid = gl.GLGridItem()
w.addItem(xgrid)
w.addItem(ygrid)
w.addItem(zgrid)
## rotate x and y grids to face the correct direction
xgrid.rotate(90, 0, 1, 0)
ygrid.rotate(90, 1, 0, 0)
xgrid.scale(1.0, 1.0, 1.0)
ygrid.scale(1.0, 1.0, 1.0)
zgrid.scale(1.0, 1.0, 1.0)
md = gl.MeshData.sphere(rows=10, cols=10, radius=5)
body = gl.GLMeshItem(meshdata=md, smooth=False, drawFaces=True, drawEdges=
True, edgeColor=(1,0,0,0), color=(1,0,0,0) )
w.addItem(body)
x = np.zeros((12,))
w.show()
app.processEvents()
time.sleep(0.01)
QtGui.QApplication.instance().exec_()
I just plot a sphere on a 3D figure. The output figure just occupy 1/4 of
the whole window, as shown below.

Thanks for your help. Look forward to your kind reply.
Best regards,
