PROBLEM TO BE SOLVED: To display the changing states of graph images on a screen in an easy-to-understand way in a recalculation mode set for the graph display. SOLUTION: A graph information input means 1 inputs the structure information as the basic graph information, and a graphic position calculation means 2 calculates the positions of graphics, based on the basic graph information. A graph history holding means 3 holds the graph information produced by adding the graphic positions calculated by the means 2 to the basic graph information inputted from the means 1. A graph information selection means 4 takes plural optional graph information out of the means 3. Then an animation producing means 5 produces the graph images 5a and 5d of graphs, based on those graph information which are take out of the means 4 and also produces the images 5b and 5c to interpolate the images 5a and 5b respectively. A display means 6 displays the results of production of the means 5 on its screen in the order of older histories. |
