GRAPH DRAWING SYSTEM, ARITHMETIC SERVER, CONTROL METHOD OF GRAPH DRAWING SYSTEM AND PROGRAM FOR ARITHMETIC SERVER

摘要

To provide a graph drawing system capable of correctly drawing even the graphs with discontinuous points.SOLUTION: The graph drawing system 1 comprises a user terminal 10 and an arithmetic server 20. The user terminal 10 transmits calculation inquiring data including information of an inputted function to the arithmetic server 20, acquires drawing point information from the arithmetic server 20 and draws a graph corresponding to the function based on the drawing point information. The arithmetic server 20 acquires the calculation inquiring data from the user terminal 10, calculates the drawing point information including the coordinates of the plural drawing points represented by the function and continuity propriety information specifying whether or not connecting two drawing points to be adjacent to each other based on the calculation inquiring data, and transmits it to the user terminal 10.SELECTED DRAWING: Figure 1
