Front Panel

The Front Panel of a VI contains the User Interface of the VI. The front panel can be simple with only a few inputs, (controls) and outputs (indicators) for a SubVI or complex with many controls, indicators, and decoration for an application interface. The Controls Palette or Quick Drop is used to select the type of control, indicator, or decoration to add to the front panel. By default the size and position of the front panel will dictate its running size and position

Organization Best Practices
