PyQtGraph – Getting Plot Item from Plot Window
In this article we will see how we can get the plot item of plot window in the PyQtGraph module. PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.) and second is to provide tools to aid in rapid application development (for example, property trees such as used in Qt Designer).Plot windows consist of two main parts: the Plot Panel containing the actual plotted graphics and the Control Panel. Plot item is basically the item which is plotted and is shown on the screen.
In order to do this we use getPlotItem method with the plot window object
Syntax : window.getPlotItem()
Argument : It takes no argument
Return : It returns PlotItem object
Below is the implementation
Plot Item : pyqtgraph.graphicsItems.PlotItem.PlotItem.PlotItem object at 0x000002AF5282B8B0
