Abstract:
1. A graphic meter display device comprising an indicator needle pointing out an input measured value and tick marks enabling reading of a value pointed by the indicator needle, visibly displaying at least the indicator needle at a position corresponding to the measured value by a graphic display, the graphic meter display device comprising: a tick mark information retaining section that, in relation to respective positions of three or more typical readable tick marks among tick marks, retains information representing display coordinates in correspondence with typical numeric values assigned to the typical tick mark positions; an indicator needle point coordinate calculation section that extracts, as a first typical numeric value and a second typical numeric value, two typical numeric values adjacent, above and below, to a magnitude of the input measured value from positions of the three or more typical tick marks according to the input measured value and that calculates an intermediate position which lies on a line segment connecting first display coordinates corresponding to the first typical numeric value with second display coordinates corresponding to the second typical numeric value and which is determined by the first typical numeric value, the second typical numeric value, and the measured value as coordinates of an indicator needle point; and a graphic display section that renders a display pattern of the indicator needle in such a way that an extremity of the indicator needle or a portion thereof is situated in a vicinity of coordinates of the indicator needle point and with reference to the coordinates of the indicator needle point.
