In this article we will see how we can get the visible range of the 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. Visible range is the boundaries of the view which is visible in scene coordinates.
We can create a plot window with the help of command given below
# creating a pyqtgraph plot window window = pg.plot()
In order to do this we use
visibleRangemethod with the plot window object
Syntax : window.visibleRange()
Argument : It takes no argument
Return : It returns QRectF object
Below is the implementation
Visible Range : PyQt5.QtCore.QRectF(-0.44795462930645247, -0.46726931351599776, 11.895909258612903, 10.934538627031994)
