PURPOSE:To execute the display of discontinuous graph by preventing an interval between two points from being linked when coordinate data (y), which continue in an (x)-axis direction, go out of a display area. CONSTITUTION:At first, a distance (x) from an xmin is set to 0 and the (y) at such a time is operated by an arithmetic part 5. Then, the (x) and (y) are respectively stored in registers 3E and 3F. Next, the (x) is set to +1 and the (y) is found in the same way. Then, they are stored in registers 3G and 3H. The data of these two points are read. When one point, out of the two points at least, is a coordinate in an area which is set to 3I-3L, the graph to connect the two points is written to a graph display buffer 6A. When the both points are coordinates out of the area, the linking of the above mentioned two points is not executed. When the data of the registers 3G and 3H are moved to the 3E and 3F, the (x) is +1, and the (x) is in the set area, the above mentioned graph preparation is repeated. |
