[Industrial applications]

The present invention relates to an apparatus for creating a composite graph combining a plurality of types of graphs.

In recent years, a composite graph has been widely used as a method of expressing a correlation between a plurality of variables. For example, the fiscal year is used as a common horizontal axis (base axis), and sales represented by a bar graph and ordinary profit represented by a line graph are superimposed and displayed on a composite graph (bar / line graph) to contribute to sales strategies. For example, since a composite graph can express the relation between a plurality of variables in an easy-to-understand manner, it is increasingly created and used in a wide range of business fields. Therefore, there is a demand for a composite graph creating apparatus capable of efficiently creating various synthetic graphs at low cost.

[Conventional technology]

In creating a graph, for each type of graph (hereinafter referred to as a basic graph) such as an individual bar graph, a line graph, etc., the appearance or decoration of the graph (for example, the size of the bar of the bar graph, the hatch in the bar frame, the unit of the scale, etc.) , And attributes) are prepared, and a graph is created by inputting these attribute information and numerical data. Conventionally, when creating a composite graph, similarly to the definitions for basic graph types such as bar graphs and line graphs, separate definitions are prepared for each composite graph such as a bar / line graph, and the composite graph is specified by specifying it. Had been created.

[Problems to be solved by the invention]

As described above, according to the conventional method, a definition field is required for each of the composite graph types as well as the basic graph types such as the bar graph and the line graph, so that when creating a new type of composite graph type, a new type is required. There is a problem that not only the definition field needs to be added, the number of definition fields increases but also a large amount of storage capacity is required, but also the expansion of the types of composite graphs is not prepared.

An object of the present invention is to provide a method that can easily create a composite graph with a small storage capacity.

[Means for solving the problem]

 FIG. 1 is a block diagram showing the principle of the present invention.

In the figure, reference numerals 2 and 3 denote a plurality of basic attribute storage means for storing the attributes of each of a plurality of basic graphs; 1 a designation unit 11 for specifying the basic attribute storage means 2 and 3 for a plurality of basic graphs to be synthesized; 4 is an input unit for designating the composite attribute storage unit 1 and inputting numerical data of a basic graph to be composited, and 5 is a designation of the composite attribute storage unit 1. This is a means for combining data of a plurality of basic graphs configured based on the attribute data from the basic attribute storage means 2 and 3 specified by the unit 11 and the numerical data from the input means 4 in accordance with the specification of the attribute unit 12.

Therefore, it is configured to output the data synthesized by the synthesizing means 5 to create a synthesized graph.

[Action]

According to the present invention, the specifying unit 11 of the composite attribute storage unit 1 specifies the basic attribute storage units 2 and 3 for storing the attributes of a plurality of basic graphs to be synthesized, the attribute unit 12 specifies the attributes of the composite graph, The synthesizing unit 5 is configured based on the attribute data from the basic attribute storage units 2 and 3 specified by the specifying unit 11 of the synthesized attribute storage unit 1 specified by the input unit 4 and the numerical data from the input unit 4. Since the data of the basic graph is synthesized according to the specification of the attribute section 12, the data synthesized by the synthesizing means 5 can be output to create a synthesized graph.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The same reference numerals indicate the same objects throughout the drawings. 2 and FIG. 3 corresponding to FIG. 1 are surrounded by alternate long and short dash lines.

In the block diagram showing the embodiment of the present invention shown in FIG. 2, a main control unit 9a controls each unit to perform a function of creating a graph.

The definition body file 1a stores basic graph information that defines attributes of the basic graph, and synthetic graph information that defines a method of synthesizing a plurality of basic graphs specified by the basic graph information. As shown in FIG. 3, it is composed of a part that defines the attributes of the composite graph and a part (pointer part) that specifies the positions of the definition bodies of a plurality of basic graphs to be composited. That is, it has the structure of a hierarchical definition body that creates a composite graph in the format specified by the composite graph information from the basic graph configured according to the specification of the basic graph information.

The hierarchical definition body will be specifically described with reference to FIG. The figure shows a bar superimposed on the same position with the year as the reference axis.
A line graph (Fig. (A)), a candlestick / bar graph (Fig. (B)) aligned vertically with the month as a reference axis, and a corresponding definition body are shown. In both FIGS. 7A and 7B, the reference axis can be defined in common, so that the synthesized graph information has the definition of the reference axis.
Further, in the case of FIG. 9A, since the length and the like can be shared for “price” and “production amount”, the composite graph information has a definition of a change axis. In the case of FIG. 7B, the “stock price” of the candlestick graph and the “volume” of the bar graph can be arbitrarily set, and thus each basic graph information has a definition of a change axis. Therefore, a desired composite graph is created by setting the graph definition information in either the composite graph information or the basic graph information according to the form of the composite graph.

The definition body input unit 16 reads out the composite graph information and the basic graph information from the definition body file 1a when a graph creation instruction is input from the keyboard 4a, and loads the information into the definition body area of the main memory 6a.

The definition body processing unit 50 reads out the synthesized graph information from the main memory 6a based on the synthesized graph name specified from the keyboard 4a, reads out the basic graph information from the pointer unit, and outputs the synthesized graph processing unit 51 and the basic graph processing unit 52. It analyzes the synthesized graph information and the basic graph information, and outputs the analysis result and numerical data (for example, price and production amount for each year) input from the keyboard 4a to the graph creation unit 5a.

The graph creation unit 5a creates graph data expressing the composite graph in a vector format based on the analysis results of the composite graph processing unit 51 and the basic graph processing unit 52 and the numerical data, and stores the graph data in the graph data area of the main memory 6a. .

The graph output unit 7a outputs the graph data from the main memory 6a to the printer 7p (or a display, a line, or the like).

Therefore, the definition field processing unit 50 obtains required composite graph information, obtains basic graph information from the pointer part and analyzes the basic graph information, and the graph creation unit 5a configures according to the specification of the basic graph information based on the analysis result and the numerical data. The basic graph is synthesized in a format specified by the synthetic graph information.

In the present embodiment, the creation of a composite graph of two types of basic graphs has been described. However, it is possible to easily create a composite graph of three or more types of basic graphs by, for example, increasing the pointer portion of the composite graph information. it can.

〔The invention's effect〕

As described above, according to the present invention, there is no need to specially prepare a definition including all graph information for a composite graph created by combining existing basic graph types, and only the information necessary for the composition is composed. By having it as graph information, it is possible to easily expand the types of composite graphs,
Also, for a composite graph including a newly added basic graph type, only the basic graph information of the basic graph type to be added may be set. Therefore, there is an effect that the types of composite graphs can be easily expanded without increasing the memorability of the definition field.
