A graphic meter display device includes a tick mark information retaining section that retains information about display coordinates of respective positions of three or more typical tick marks among tick marks, in correspondence with typical numeric values assigned to the respective positions; an indicator needle coordinate calculation section that extracts two typical numeric values adjacent, above and below, to a magnitude of the input measured value according to the input measured value as a first typical numeric value and a second typical numeric value from the positions of three or more typical tick marks and that calculates, as coordinates of an indicator needle point, an intermediate position, which lies on a line segment connecting coordinates corresponding to the first typical numeric value to coordinates corresponding to the second typical numeric value and which is determined by means of the first typical numeric value, the second typical numeric value, and the measured value; and a graphic display section that renders a display pattern of the indicator needle in a vicinity of the coordinates of the indicator needle point and with reference to the coordinates of the indicator needle point.
