Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar graph display device which can be operated by pointing a bar area of a bar graph with a mouse or the like.

[0002]

2. Description of the Related Art In a conventional bar graph display device, a button region is provided separately from the bar region when the bar region of the displayed bar graph is designated by a pointing device such as a mouse. FIG. 6 is a diagram showing an image of a conventional bar graph display device.

As shown in FIG. 6, in the conventional device of this type, a button area A61 is provided as an operation area separately from the bar graph 60.
1, a button area B612, and a button area C613 are provided, and the operator designates a button area corresponding to a rod area to be designated by the pointing device. Here, a program that performs a process for the bar area corresponding to the button area by designating the button area is defined in advance.

For example, when the operator wants to operate the stick area A601, the button area A611 is designated by the pointing device. When the button area A611 is designated, the processing program related to the stick area A601 is activated, and the operator can execute the processing related to the stick area A601.

[0005]

However, the conventional bar graph display device has the following problems.

Since the bar area and the button area of the displayed bar graph are displayed at different positions, and the display and the operation target are different, the bar area in which bar graph and which button area are operated by the operator. It is necessary to confirm that it is compatible, and the operability is poor.

Since it is necessary to display both the bar area and the button area of the bar graph, a large space is required on the display device, and when the display space is small, the bar graph is displayed small.

When a button area is designated by the pointing device and a plurality of stick areas correspond to each other, different processing cannot be performed for each stick area.

The present invention has been made in view of the above-mentioned points, and improves the operability of the operator, and it is possible to specify a bar graph area even with a small display space, and further, for each bar area. An object is to provide a bar graph display device capable of performing different processing.

[0010]

In order to solve the above problems, the present invention provides a bar graph display device for displaying bar graph coordinate axis display data and a bar graph based on the coordinate values of each bar area in the bar graph. Storage means for storing the coordinate value of each rod area, coordinate value detection means for detecting the coordinate value designated by the pointing device, and the coordinate value based on the coordinate value storage data of each rod area of the storage means. The coordinate value detected by the detection means, the area determination means for determining whether or not included in each of the bar areas, the area determination means, the coordinate value is included in the bar area. When it is determined that the stick area is present, the processing corresponding to the stick area is executed.

[0011]

According to the present invention, the bar graph display device is configured as described above, and the bar area of the bar graph is directly specified by the pointing device to execute the processing corresponding to the bar area in the bar graph including the specified coordinate values. , The display and the operation target are the same, and even if the display space is small, it is possible to specify the area only by looking at the bar graph.

ROM, 14 is a coordinate value detection unit for detecting coordinate values on the bar graph display unit 16, 15 is a region determination unit, 16
Is a bar graph display unit composed of a bitmap display or the like. The coordinate value detection unit 14 and the area determination unit 15 form a button operation unit 17.

FIG. 2 is a view showing an example of a bar graph displayed on the bar graph display section 16. FIG. 3 shows the RA of this embodiment.
It is a figure showing the memory map of the data stored in M12. As shown in FIG. 3, the RAM 12 is divided into a bar graph coordinate axis display data area 301 and a bar area data area 302. The data used in this embodiment will be described below with reference to FIGS. 2 and 3.

The bar graph coordinate axis display data area 301 includes the origin coordinate value (311) of the bar graph of the displayed bar graph 20 and the vertical and horizontal size values (312) of the bar graph.

The stick area data area 302 contains stick area data and a processing program, and the stick area data is composed of a stick reference position, a stick width size, and a stick height size. For example, the bar area 201 shown in FIG.
For the bar area data of, the bar reference position B1 (B1x
1, B1y1), bar width size W1, bar height size H
1, and the processing program P1 corresponding to the bar area 201 is B1x1, B1y1 (321), W as shown in FIG.

(2) The coordinate value detecting section 14 operates in step S4.
The coordinate position of the designated portion designated by 01 is detected. For example, when P is designated in the bar graph 50 shown in FIG. 5, the coordinate value (Px, Py) of P is detected (step S402). The detected coordinate value is temporarily stored in a predetermined address of the RAM 12 under the control of the CPU 10.

It is determined that y) is inside the bar graph 50 (step S403).

(4) In order to determine which bar area contains the coordinate value (Px, Py) of P detected in step S402, each variable is initialized. Here, MAX indicates the total number of bar areas displayed on the bar graph 50, and i indicates the i-th bar area (step S404).

(5) The data of the i-th stick area is read from the stick area data area (302) of the RAM 12, and C
Under the control of the PU 10, the area discriminating unit 15 causes the area determination unit 15
x, Py), Bixi ≦ Px <Bixi + Wi, Biii ≦ Py
<Biii + Hi relationship is determined. (Step S40
5, step S406, step S407, step S
408).

(6) If both are satisfied in step S408, the coordinate value of P (Px, P
y), it is determined whether or not there is a processing program Pi (step S409), and if it exists, the processing program Pi is activated under the control of the CPU 10 (step S410). Here, the processing program Pi is stored as Pi (334) in the memory map of FIG.

(7) Steps S405 and S40
6, if any of step S407 and step S408 is not satisfied, i = i + 1 is set (step S
411), if it does not exceed MAX, step S405.
It returns to (step S412).
