Abstract

A display control method executed by a client terminal, includes: accepting a first and second formulas; displaying a first coordinate system having a first coordinate range corresponding to the first formula, in a first area, and a second coordinate system having a second coordinate range corresponding to the second formula, in a second area, on a display screen of a display; accepting a user operation of moving one area of first and second areas to overlap at least a part of the one area onto the other area of the first and second areas; and in response to the user operation, displaying, on the display screen, an integrated coordinate system having a coordinate range for integration determined based on the first and second coordinate ranges, and drawing first and second graphs representing the first and second formulas, at the integrated coordinate system.

First claim

The invention claimed is:

1. A display control method executed by a client terminal, the display control method comprising:
accepting input of a first formula and a second formula;
controlling a display to display on a display screen:
a first graph area showing a first coordinate system having a first coordinate range and a first graph corresponding to the first formula inputted; and
a second graph area showing a second coordinate system having a second coordinate range and a second graph corresponding to the second formula inputted;

accepting a user operation of moving one of the first graph area and the second graph area displayed on the display screen so as to overlap at least a part of the one of the first graph area and the second graph area onto the other of the first graph area and the second graph area; and
in response to acceptance of the user operation,
determining whether the first coordinate range and the second coordinate range are different; and
in response to determining that the first coordinate range and the second coordinate range are different:
setting a coordinate range which is the same as the first coordinate range, as a coordinate range for integration; and
controlling the display to display on the display screen:
an integrated coordinate system having the coordinate range for integration;
the first graph based on first plot points calculated by using the first coordinate range and the first formula in the integrated coordinate system; and
the second graph based on second plot points calculated by using the coordinate range for integration and the second formula in the integrated coordinate system.

2. A display control method executed by a client terminal, the display control method comprising:
accepting input of a first formula and a second formula;
controlling a display to display on a display screen:
a first graph area showing a first coordinate system having a first coordinate range and a first graph corresponding to the first formula inputted; and
a second graph area showing a second coordinate system having a second coordinate range and a second graph corresponding to the second formula inputted;

before acceptance of a user operation of moving one of the first graph area and the second graph area displayed on the display screen so as to overlap at least a part of the one of the first graph area and the second graph area onto the other of the first graph area and the second graph area:
storing the first formula, the first coordinate range and first plot points in a storage while associating the first formula, the first coordinate range and the first plot points with each other, wherein the first plot points are plot points calculated by using the first coordinate range and the first formula; and
storing the second formula, the second coordinate range and second plot points in the storage while associating the second formula, the second coordinate range and the second plot points with each other, wherein the second plot points are plot points calculated by using the second coordinate range and the second formula;

accepting the user operation; and
in response to acceptance of the user operation:
determining whether recalculation of the first plot points, the second plot points or the first plot points and the second plot points is necessary;
in response to determining that recalculation is necessary:
setting a coordinate range which is the same as the first coordinate range, as a coordinate range for integration, and sending the second formula and the coordinate range for integration to a server; and
receiving third plot points from the server, wherein the third plot points are plot points calculated by the server based on the second formula and the coordinate range for integration; and

controlling the display to display on the display screen:
an integrated coordinate system having the coordinate range for integration;
the first graph based on the first plot points read from the storage in the integrated coordinate system; and
the second graph based on the third plot points received from the server in the integrated coordinate system.

3. A display control method executed by a client terminal, the display control method comprising:
accepting input of a first formula and a second formula;
controlling a display to display on a display screen:
a first graph area showing a first coordinate system having a first coordinate range and a first graph corresponding to the first formula inputted; and
a second graph area showing a second coordinate system having a second coordinate range and a second graph corresponding to the second formula inputted;

accepting a user operation of moving one of the first graph area and the second graph area displayed on the display screen so as to overlap at least a part of the one of the first graph area and the second graph area onto the other of the first graph area and the second graph area; and
in response to acceptance of the user operation,
determining whether the first coordinate range and the second coordinate range are the same; and
in response to determining that the first coordinate range and the second coordinate range are the same:
setting a coordinate range which is the same as the first coordinate range and the second coordinate range, as a coordinate range for integration;
reading, from a storage, first plot points calculated by using the first coordinate range and the first formula and second plot points calculated by using the second coordinate range and the second formula; and
controlling the display to display on the display screen:
an integrated coordinate system having the coordinate range for integration;
the first graph based on the first plot points read from the storage in the integrated coordinate system; and
the second graph based on the second plot points read from the storage in the integrated coordinate system.

4. The display control method according to claim 3 the display control method comprising:
before acceptance of the user operation:
storing the first formula, the first coordinate range and the first plot points in the storage while associating the first formula, the first coordinate range and the first plot points with each other; and

storing the second formula, the second coordinate range and the second plot points in the storage while associating the second formula, the second coordinate range and the second plot points with each other.

5. A display control method executed by a client terminal, the display control method comprising:
accepting input of a first formula and a second formula;
controlling a display to display on a display screen:
a first graph area showing a first coordinate system having a first coordinate range and a first graph corresponding to the first formula inputted; and
a second graph area showing a second coordinate system having a second coordinate range and a second graph corresponding to the second formula inputted;

accepting a user operation of moving one of the first graph area and the second graph area displayed on the display screen so as to overlap at least a part of the one of the first graph area and the second graph area onto the other of the first graph area and the second graph area; and
