PURPOSE:To speedily generate an exact graph by displaying a percentage to the whole area of a partial area which is defined by the present cursor position from an origin of a graph, and a percentage to the whole area of a partial area which is defined by a start point and the present cursor position, in the vicinity of a cursor. CONSTITUTION:In case of defining a partial area of a graph by a start point and an end point by using a pointing input device, when a cursor is moved by the pointing input device, a percentage to the whole area of a partial area shown by a present cursor position 17 from an origin is displayed, as the cursor moves. A user can determine a start point 10 of the partial area of an object quantity, and after the start point 10 is determined, a percentage 19 of, from the origin to the present cursor position, and from the start point 10 to the present cursor position is displayed by a numeral, therefore, the user can determine an end point 11 of the partial area of an object quantity.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an information processing device such as a graphic creation device,
The present invention relates to a graph creation method for creating a document containing graphs with high presentation effect.

[Conventional technology]

Traditionally, when drawing graphs using a computer, tools such as Stellar System's BGM (B07M) (for details, refer to Stellar System's Business Graph BG/M manual) were used. , numerical data was input, and it was automatically converted and displayed in various graphs such as pie glass bar graphs.

These tools are very easy and convenient for graphing numbers. However, there is a problem in that the graphs that can be created can only be of the type, shape, and size of the prepared graph.

On the other hand, there are software tools that use basic shapes such as rectangles, polygons, and nine arcs to create documents for presentation presentation with emphasis such as shading.

A well-known example of such a software tool is Apple's Lisa-Draw (see Apple's Lisa-Draw manual for details).

The above method uses a pointing input device called a mouse, rather than defining the shape by entering numerical values.
A method for quickly drawing ellipses, rectangles, etc. is adopted by specifying the start and end points that define the circumscribed rectangle of the figure. It also has a function that displays the size of the circumscribed rectangle connecting the start point and end point as a numerical value at the cursor location.

However, when drawing band graphs and bar graphs, and especially when drawing ellipse (circle) graphs, it is extremely difficult to define a partial area of the graph that corresponds to a percentage.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, no consideration was given to creating a graph without inputting numerical values.

An object of the present invention is to provide a method for quickly creating accurate graphs without inputting numerical values.

[Means for solving the problem] The above purpose is to create a partial area of a graph (sector shape for a pie chart, rectangle for a bar graph) in a software tool that has a graphic creation function. By displaying the percentage of the partial area defined from the origin of the graph to the current cursor position to the total area, and the percentage of the partial area defined from the starting point to the current cursor position to the total area, in the vicinity, achieved.

[Effect]

When using a pointing input device to define a partial area of a graph using a start point and an end point, when you move the cursor using the pointing input device, as the cursor moves, the percentage of the partial area indicated by the current cursor position relative to the total area increases from the origin. The display allows the user to determine the starting point of a partial area of the desired quantity. After the starting point is determined, the percentage from the origin to the current cursor position and the percentage from the starting point to the current cursor position are displayed numerically, allowing the user to determine the end point of the partial area of the desired quantity.

The numerical value 2o indicates a line indicating the boundary of the partial area 21, and the same reference numerals as in FIG. 1 correspond to the same parts.

Now, a method in which the user 6 creates a graph by looking at the numerical values 18 and 19 indicating percentages displayed near the cursor will be explained. As a specific example, the case of creating a pie chart shown in FIG. 2 will be described.

Before explaining this processing operation, the structure of the table of the present invention used for this processing operation will first be explained.

, 40 to 47 are various parameters of each graphic data. In this example, the graphic data 3o is composed of data defining a sector forming a partial area of a pie chart. Note that this graphic data table exists in the memory 1 shown in FIG.

As shown in FIG.
A flag 32 indicating whether it is invalid, a record length 33 indicating the length of this figure data, a figure type 34 (in this case, a fan), a figure pattern code 35 (also a hatch), and coordinates that define the shape of the figure. It is composed of point parameters 36 to 39 (similarly, the starting point and ending point of the circumscribed rectangle definition of the circle, and the starting point angle and ending point angle of the fan shape definition). The graphic data 31 is also composed of similar parameters 42 to 47.

The processing operation in the above configuration will be explained below using FIG. 4.

FIG. 4 is a flowchart showing the processing operation in one embodiment of the present invention, and the CPU 2 shown in FIG. 1 executes the processing steps shown in FIG. Perform processing operations.

The process begins at block 50. First, the user 6 specifies the type of graph (block 51).

Here, it is assumed that a pie chart is specified. The CPU 2 calls a processing module according to the type of graph and waits for the user 6 to input shape parameters for the entire graph (block 52).

The user 6 uses the pointing input device 5 to indicate the starting point 10 and the ending point 11° that define the circumscribed rectangle 12 of the circle 13 in order to define the size and position of the circle 130 (block 53).
.

The CPU 2 uses the current cursor position as a temporary end point in order to feed back the size of the circle 13 to the user 6 until the end point 11 is specified after the start point 10 is input.
Temporarily display the circle as a rubber band. When the end point 11 is specified, the CPU 2 draws a graph structure according to the type of graph, that is, a circle 13 (block 54).

Next, an example will be described in which the user 6 defines the sector 21 that is a partial area of the graph (blocks 55 to 60).

In order for the user 6 to define the starting point angle 16 of the sector 21, the CPU 2 displays the percentage 18 of the partial area from the origin 14 to the current cursor position to the total area (block 5).
5). The user 6 moves the cursor 1 directly using the pointing input device 5 until the desired starting point angle 16 is found.

When the desired starting point angle 16 is determined, the sector 21
Specify fill attributes (hatch pattern, etc.) for (
block 56). To specify the fill attribute, use the end point angle 21
It is also possible to set (or change) after specifying.

The CPU 2 displays the percentage 19 from the starting point 16 to the current position indicated by the cursor 17 and the percentage 18 from the origin 14 at the cursor position (block 57). User 6 is
The cursor 17 is directly moved using the pointing input device 5 until the desired end point angle 21 is found.

When the target end point angle 21 is determined, an instruction is given to determine the end point angle (block 58).

The CPU 2 fills in the fan shape 21 with the currently set fill-in attribute and finalizes the fan shape.

Thereafter, the sector 210 figure data 30 is registered in the figure table of FIG. 3 (block 59).

This graphic data 30 is used when processing a graph for presentation purposes. Next, move to block 55 to define another sector, or block 6 to finish.
Let user 6 decide whether to proceed to step 1 (block 60)
, block 61, the process ends.

The above description has been made using a pie chart as an example, but an ellipse chart can also be defined in the same way.
