This is a QGraphicsItem subclass and thus may only be used from within a GraphicsView. All of these will accept the same basic arguments which control how the plot data is interpreted and displayed: x - Optional X data; if not specified, then a range of integers will be generated automatically. setObjectName ( "MainWindow") MainWindow. Here are the examples of the python api pyqtgraph.plot taken from open source projects. Python PlotWidget.plot - 20 examples found. setObjectName ( "centralwidget") Thus almost anything you can do with the usual pyqtgraph classes can also be done with these objects and the results will appear in the remote process. Example-1: Draw a simple line graph. This is (in my opinion) matplotlib's greatest weakness. Select an item from the list to view its source code and double-click an item to run the example. An example of data being processed may be a unique identifier stored in a cookie. See the plotting example for a demonstration of these arguments. Most importantly: 1) Qt GUIs are composed of QWidgets, 2) A special widget called QGraphicsView is used for displaying complex graphics, and 3) QGraphicsItems define the objects that are displayed within a QGraphicsView.
