A device for a screen for the display of the graphic representation of the evolution of the atmospheric pressure or of the altitude over a period database

摘要

The display (1) is composed of two sections with the right-hand side point grouping (4) showing the most recent variations and the left-hand side grouping (3) showing older variations. The two sections have differing point grouping to represent the time intervals covered i.e.2 points (42) and 4 points (32), different column heights (40,30) and different assigned values. The points are illuminated to show average values over each interval of the display period. The display is controlled by computer.
