Sizing of panels

A panel’s size can be varied easily by defining the sizeX and sizeY properties. The sizeX property defines the width and sizeY property defines height of a panel in cells count. These properties will be helpful in designing a dashboard, where the content of each panel may vary in size.

The following sample demonstrates the sizing of panels within the dashboard layout using the sizeX and sizeY properties of the panels.
