Abstract: An information displaying device of the type useful in charting various data embodying a plurality of elongated data displaying elements retained in place on a mounting frame by spring-loaded holding strips which grip the ends of the display elements, by individual springs carried by the display elements, or by flanges formed on the mounting frame. The device also includes indicator pegs received by rows of holes in the display elements, the holes being formed by piercing to leave annular flanges that grip the pegs but are not subject to the problem of shaving material from the pegs. A flexible cord is associated with each indicator peg and is rectractable when not in use into the space beneath the display elements; in one form of the device a spring mechanism is secured to the mounting frame to facilitate retracting of the cord.
