PyQtGraph – Setting Plot Window Opacity
In this article we will see how we can set the opacity 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. Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.
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
setWindowOpacitymethod with the plot window object
Syntax : window.setWindowOpacity(n)
Argument : It takes float value as argument
Return : It returns None
Below is the implementation
