Graphical depictions of a statistical quantity, most often the player-character's current status. Most often takes the form of a straight or circular line that empties and fills as the stat's value changes.
A graphical representation is often prefered to a numerical point-count display, as it reduces the feeling that the game is entirely numbers-driven, despite the fact that all computerized games must be so. RPGs are the perennial exception, as long-time players really seem to like numbers. A graphical display is also easier to understand at a quick glance, which is all you can find time for in a non-turn-based setting.
Ammo counts are usually depicted as just a set of numbers, often rounds in weapon/rounds in reserve; however, a graphic to accompany this quantity is becoming more common.
