A specifying unit specifies a plot range and the plot spacing of a diagram represented by a desired function input by an input unit; a correlating unit correlates the specified plot range and plot spacing of the diagram with a position on a display unit; and a plotting unit plots the diagram with arbitrarily spacing on the display unit.

In the information processing apparatus having a function of displaying a plurality of graphs, when information on mathematical expressions for drawing a plurality of graphs and information on scales on a plurality of axes associated with the graphs is input from an input portion, a drawing data conversion portion converts the information on a plurality of expressions into graph drawing data for drawing a plurality of graphs and converts the information on scales on a plurality of axes into axes drawing data to be used for graduating axes for respective graphs. A graph drawing portion draws a plurality of graphs such that they overlap each other about a common axis based on the graph drawing data and axes drawing data obtained as a result of the conversion and draws axes having different scales for respective graphs on the same screen of a display portion. An arrangement may be provided to draw a trace pointer on a graph to be traced and an axis pointer on the axis for the graph when the graph to be traced is specified. This makes it possible to clearly display transitions of values on a graph from among graphs having different ranges displayed on the same screen for clear readability.

The invention provides a calculator wherein it is possible to start an operation on the basis of an inputted formula and successively know the progress processes of operation until an operation result is obtained. An inputted formula edited on the basis of the data inputted from a keyboard is once displayed and the calculator is placed in the state of waiting for key entry. Then, when a Enter key is pressed down, only the operator codes selected among plural operator codes in the inputted formula in accordance with the priority order of operation are processed and a process formula as the result of the processing is displayed. Thereafter, every time the Enter key is pressed down, the operation is executed in accordance with the priority order and the process formulas obtained in the respective operations are successively displayed. Accordingly, the user of the calculator can successively recognize the respective intermediate processes as process formulas as well as the operation result of the inputted formula.
