There is an example program bundled with the pyqtgraph library though, which is how I learned about the class. The following are code examples for showing how to use pyqtgraph.PlotWidget().They are from open source Python projects. You can vote up the examples you like or vote down the ones you don't like.

PlotItem also provides some basic analysis functionality that may be accessed from the context menu. Use plot () to create a new PlotDataItem and add it to the view. Use addItem () to add any QGraphicsItem to the view. This class wraps several methods from its internal ViewBox: setXRange , setYRange , setRange , autoRange , setXLink ,...
