PURPOSE:To perform tracing speedily up to an optional point by moving a pointer at optional movement intervals. CONSTITUTION:When a trace movement key 1f is operated after graph display operation, in-movement data P which is optionally set in advance is added to the X value in an X register 7f. Then the X value in the X register 7f is substituted in a function equation Y=f(X) stored in an equation storage part 8 to calculate the Y value, which is stored in a Y register 7g. Then a blinking dot is displayed as the pointer on the displayed function graph. Thus, the movement width data in a P register 7e is added to the X value through the operation of the trace movement key 1f and the pointer moves by the movement quantity at a time. |
