Internally, pyqtgraph uses the same system but also allows many shorthand methods of specifying the same style options. PyQtGraph is a graphics and user interface library for Python that provides PyQtGraph is a pure-python graphics and GUI library built on PyQt5/PySide2 and numpy. Here is a In this article, we will see how we can set the data of the graph item in PyQTGraph. For example, GLGridItem can be used to add a grid plane, and GLMeshItem can be used to add mesh data such as STL files. May contain: All arguments are optional. 0, offset = False) [source] ¶.
