Picture Functions VIs (PDA Module, Touch Panel Module)
Owning Palette: Graphics & Sound VIs
Use the Picture Functions VIs to create visual representations of data.
Many of these picture VIs use clusters to define points and rectangles. The VIs related to drawing text use clusters and enumerations to describe the font choice and the positioning of the text.
