PURPOSE:To automatically draw an appropriate graph at a high speed by introducing an intermediate table, a drawable graph kind decision rule, ad a drawing priority order decision rule. CONSTITUTION:An input/output processing means 1 receives the kind of graph to be drawn from a user, and an intermediate table generation means 2 refers to an intermediate table generation regulation to prepare the intermediate table. A drawable graph kind decision means 3 selects all kinds of drawable graph kinds to the intermediate table received while compared by the drawable graph kind decision rule 10, and a priority order decision means 4 decides the drawing priority order of the kind of graph selected by the drawable graph kind decision means 3. Further, a graph drawing means 5 prepares graph data in order of the highest drawing priority order, draws the graph automatically, inputs the graph required by a user to obtain the final graph data. A priority rule updata means 6 updates the drawing priority order decision rule 10 so as to adjust the appropriateness to the actual results of the user. Thus, the appropriate graphs are automatically displayed successively. |
