We include the appropriate header and the QHBoxLayout, which allows us to place multiple widgets in the main window. We create a new master QWidget, which will hold the picture of the falling ball and the graph. Then, we create an instance of the KPlotWidget. We define a new layout to place the things on the master. Here we choose horizontal layout but vertical and grid layout exist. Which can be further divided. Therefore, almost endless possibilities.
