GRAPH widgets can be used to visualize data. Typical applications for GRAPH widgets are showing measurement values or the curve of a function graph. Multiple curves can be shown simultaneously. Horizontal and vertical scales can be used to label the curves.

A grid with different horizontal and vertical spacing can be shown on the background. If the data array does not fit into the visible area of the graph, the widget can automatically show scroll bars which allow scrolling through large data arrays.
