Abstract¶ PyQtGraph is a plotting library with high performance, cross-platform support and interactivity as its primary objectives. import getConfigOption from. opengl is based on the deprecated OpenGL fixed-function pipeline. The 3D graphics system in pyqtgraph is composed of a view widget and several graphics items (all subclasses of GLGraphicsItem) which can be added to a view widget. These can be accessed using the setConfigOptions() Enable OpenGL in GraphicsView. 04. Qt import QtCore, QtGui, QtWidgets If you don't need OpenGL, here is a simpler solution using pyqtgraph.
