1. A graph drawing device, comprising:

  • a target-data acquiring unit that acquires a plurality of items of target data each containing time data and two-dimensional data in two specific dimensions other than time;

    a differential calculating unit that calculates a differential time between the time data and a reference time concerning each of the target data acquired by the target-data acquiring unit;

    a differential-data generating unit that generates a plurality of items of differential target data each obtained by replacing the time data contained in each of the target data with the differential time calculated by the differential calculating unit; and

    a drawing-data generating unit that converts each of the differential target data generated by the differential-data generating unit into three-dimensional coordinate data in a three-dimensional coordinate system formed by a time axis and a coordinate plane formed by the two specific dimensions, and generates drawing data on a three-dimensional graph showing a plurality of items of the three-dimensional coordinate data converted.
