The commonly used data drawing tools in LabVIEW are waveform chart and waveform chart. Waveform diagram is a special numerical control for displaying one or more curves, which is generally used to display data collected at a constant rate. The waveform chart will retain the historical data updated before, which is also called buffer.
Labview is a graphical programming language that uses icons instead of text lines to create applications. Using data flow programming, the data flow between nodes in the program block diagram determines the execution order of VI and functions.
