axes not displaying correctly on external displays

[kyle.p...@gmail.com]

I have been struggling with an axes display issue since upgrading PyQt4 to PyQt5 on my Windows 10 machine. Essentially, when I make a simple plot using pyqtgraph, the x axis does not stretch across the bottom of the window, and the y axis is not joined to the x axis in the lower left corner. Furthermore, the trace is not accurately represented by the axis labels at large x values or small y values. This issue only exists when the plot is displayed on my external monitor - the plot appears to look just fine in my laptop display.

The plots are displayed below (left - external display, right - laptop display), and were generated with:

import pyqtgraph as pg
pg.plot([0,1,2,3,4,5,6,7,8,9],[1,2,4,5,7,8,10,11,13,14]) 

pg.QtGui.QApplication.exec_()

 

I've also posted the problem to stackexchange here. I am using python version 3.6.1, pyqtgraph version 0.10.0, PyQt5 version 5.9, pyqt version 5.6.0, and qt verstion 5.6.2. I suspect that this may be an issue related to the Qt DPI scaling added to more recent versions of Qt. Any help would definitely be appreciated. Thank you.
