Graph Component provides 2D plotting facilities, it accepts any number of curves and provides user with ability to zoom, resize and print.
Graph Component works in two modes:

Offline Mode: In this mode the whole drawing points must be provided, the components render this points after calculating the appropriate scale. This mode supports linear and log scale, also it supports curve, bar, and stairs drawing styles.

Online Mode: In this mode the components draw the incoming signals directly and perform the appropriate scrolling and tracking, simply it works like electronic oscilloscope.
