DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus having a graph creating function of graphing numerical data in a table format and managing the data as a graphic, and in particular, divides the numerical data in a table format into a data sequence to be graphed. The present invention relates to a data string division boundary determination method suitable for the above.

[0002]

2. Description of the Related Art In recent years, many document creation apparatuses (word processors) have a graph creation function of graphing numerical data in a table format and managing the data as graphics.

In order to create a graph with this type of document creation device, it is necessary to first create numerical data in a table format in a document. As shown in FIG. 7, the table format (table format data) in which the numerical data is set is created by a ruled line frame composed of vertical and horizontal ruled lines (character ruled lines, table ruled lines) composed of ruled line characters. . In the table format having such a structure, the division boundary when dividing the numerical data into data strings to be graphed is indicated by ruled lines, so that the division can be easily performed.

[0004]

As described above, in a conventional document creating apparatus having a graph creating function, the tabular data in which numerical data that can be graphed is set is data for converting the numerical data into a graph. When dividing into columns, it is necessary to configure (create) using ruled lines so that the dividing boundary can be easily identified. However, creating a table using ruled lines is complicated, and there is a problem that an extra number of table constituent rows (data rows + one extra row) is required (in the example of FIG. In addition to the rows, 5 + 1 rows are required for horizontal ruled lines, that is, an extra 6 rows are required).

The present invention has been made in view of the above circumstances, and an object of the present invention is to simplify a data division boundary even if tabular data in which numerical data which can be graphed is set is configured without using ruled lines. It is another object of the present invention to provide a document creating apparatus that can correctly divide data into data strings.

[0006]

According to the present invention, there is provided a table in which a data column is divided by a blank column in which all the same digits are all blank and a row boundary, and numerical data to be graphed are set in the data column. Storage means for storing the format data, range specification means for specifying the numerical data range to be graphed in the tabular data stored in the storage means, and Blank column detecting means for detecting blank columns in units of digits for tabular data within the specified range, and for detecting blank column groups of numerical data in tabular data falling within the range specified by the range specifying means. It is characterized in that it is divided into data strings for each area not including the blank string, sandwiched between the blank strings detected by the means.

[0007]

In the above configuration, the table format (table format data) is
The data column is divided by a blank column in which all the same digits are blank and a row boundary, and numerical data that can be graphed is set in the data column. Therefore,
If the range specifying means specifies a numerical data range to be graphed in the table format having the above structure, the blank string detecting means targets the table format within the specified range in units of digits. By detecting a blank column, it is possible to obtain a division boundary (vertical division boundary) at the time of dividing into a data sequence to be graphed, even in a table format not using ruled lines, and within a specified range. The numerical data group in the table format can be divided into data strings for each area that does not include a blank string, sandwiched between blank strings detected by the blank string detecting means.

FIG. 13 is a diagram illustrating a data string division result for the tabular data of No. 3;

First, graph drawing is a numerical value (numerical data).
Is a function for creating a graph (graph figure) in a document by picking up numerical data in a specified range from a table format (table format data) in which is set, and setting the type of graph and the like. Therefore, in order to draw a graph, it is necessary that a table format in which numerical values are set be created and displayed on a screen. The table does not need to be created using ruled lines (table ruled line, ruled line characters). The tabular numerical data to be graph-drawn is set in the document data and stored in the document buffer 21 in the RAM 2 together with a normal character string.

Here, it is assumed that the tabular data set in the document data is as shown in FIG. Note that in the example of FIG. 3, the tabular data is not created using ruled lines (table ruled lines, ruled line characters). That is, in the tabular data in FIG. 3, the data column is divided by a blank column (space code column) in which all the same digits are blank (space in this case) and a row boundary, and the data column can be a graphing target. It has a structure in which numerical data is set. Here, the space does not necessarily need to be keyed. In a commercially available document creation device such as a Japanese word processor, taking the first row of the table format in FIG. 3 as an example, the cursor is positioned at the fifth digit (the fifth digit is used as a character input position). When a character (here, a numerical value "1") is input, a space is automatically inserted in each of the first to fourth digits, and then the cursor is moved to the twelfth digit to enter a character (here, a numerical value "2"). Is input, a space is automatically inserted in each of the sixth to eleventh digits. Therefore, the table format of the structure of FIG. 3 can be created more easily than the table format of the structure of FIG. 7 using ruled lines.

Now, in order to create a graph figure by converting the tabular data as shown in FIG. 3 into a graph, a specific key of KB4 is operated to set a graph drawing mode, and the type of graph and the object to be graphed are set. It is necessary to specify and input various graphed data such as a range of numerical data, a graph creation area, and the like stepwise, for example. In this embodiment, when the graph drawing mode is set in a state where the document including the tabular data to be graphed is displayed on the display unit 6, the display screen displays the graph type for selecting the graph type. The screen is switched to the selection screen. If the graph type is selected in this state, the display returns to the display screen of the document including the tabular data, and FIG.
As shown in (1), a guidance message for designating and inputting the starting point of the numerical data range to be graphed in the tabular data is displayed at the bottom of the screen.

When the input guidance message for designating the start point of the numerical data range is displayed, the user operates the cursor keys to display the numerical value to be graphed on the display screen shown in FIG. Specify the start point of the data range with the cursor and press the [Select / Execute] key. In FIG. 4A, the cursor is designated as the starting point at the line / column position (shaded portion) at the upper left corner of the table format.

When the [select / execute] key is pressed while the input guidance message for specifying the start point of the numerical data range is displayed, the CPU 1 stores information on the start point designated by the cursor in the work buffer 24 at that time. At the same time CPU1
Deletes the guidance message for specifying the start point of the numerical data range, and displays a guidance message for requesting the user to specify the end point of the numerical data range, as shown in FIG. 4B.

When the input guidance message for specifying the end point of the numerical data range is displayed, the user operates the cursor keys to display the numerical value to be graphed on the display screen shown in FIG. Specify the end point of the data range with the cursor and press the [Select / Execute] key. In FIG. 4B, the cursor is designated as the end point at the line / column position (shaded portion) at the lower right end of the table format.

When the [select / execute] key is pressed while the input guidance message for specifying the end point of the numerical data range is displayed, the CPU 1 stores information on the end point designated by the cursor in the work buffer 24 at that time. And CPU1
Executes the division processing according to the division processing program 36 in the graph generation program stored in the graph generation program area 35 as described below.

First, the CPU 1 obtains information of the starting point and the ending point of the numerical data range in the table format from the work buffer 24,
A row / column (checked row / column) position to be checked to detect a division boundary on the target table format is set as a start point (steps S1 and S2).

Next, the CPU 1 checks whether or not the check point (character code) on the target tabular data (here, tabular data shown in FIG. 3) is a space (space code) (step S1). S3). Here, codes such as line feeds and page breaks are handled in the same manner as space codes. If it is a space (space code), the CPU 1 checks whether the line position of the check point matches the line position of the end point (step S5). Advance one step (step S5), and return to the space check of step S3. Here, if the new check point at which the line position has been advanced by one is a space, the process again proceeds to step S4 as described above, and it is checked whether the line position of the check point matches the line position of the end point. Can be

Therefore, if the same digit (check digit) as the check point is all spaces in the designated numerical data range on the tabular data, that is, it is a space column (space code column). Then, the processing of the above steps S5, S3 and S4 is repeated until the line position of the check point is advanced to the line position of the end point. Then, when it is determined in step S4 that the row position of the check point matches the row position of the end point,
The CPU 1 marks the check digit (current digit) on the work buffer 24 (a black triangle in FIG. 5) assuming that the check digit is a space column representing a vertical division boundary instead of a vertical ruled line. (Step S6).

When executing the step S6, the CPU 1 checks whether or not the check digit has reached the end digit (step S7). If not, the CPU 1 checks the check digit to the value of "current digit position + 1". Each is updated starting from the line (step S8). Then, the CPU 1 proceeds to step S3
Returning to the subsequent processing, it is checked whether the new check digit is a space column. If it is detected that even one of the check digits is not a space, the process jumps from step S3 to step S7 at that point, and if it is detected that the check digit is a space column, the check digit is marked. After that (step S6), the process proceeds to step S7.

Eventually, when the check digit reaches the end digit and the determination in step S7 is YES, the CPU 1 detects space columns (vertical division boundaries) within the designated numerical data range on the tabular data. Is determined to have been completed, and the adjacent marks among the previously added marks are combined into one (step S9). That is, the CPU 1 puts the entire adjacent space row as one vertical division boundary.

From the tabular data as shown in FIG. 3 created without using the ruled line, a column in which all the same digits are spaces in the designated numerical data range is replaced by a space column instead of the vertical ruled line. 5 are marked as shown in FIG. 5, and if there are adjacent space columns, they are combined into one to form a vertical division boundary, thereby forming a table format as shown in FIG. 3. Can be divided into data columns for each data column (data item) within the designated numerical data range as shown in FIG. In order to divide the table format for each row, no special processing is required since the row boundary is a horizontal division boundary (virtual horizontal ruled line).

In the above description, a mark is applied to the corresponding digit so that the detected space column can be easily understood. However, the present invention is not limited to this, and the digit information may be provided. In this case, only the information of the starting digit and the ending digit of the continuous space column need be left in correspondence with the process of combining adjacent marks into one. When a space column is detected, the digit position is used as the start column and end column of one vertical division boundary, and if a space column is detected continuously at the next column, the end column is newly detected. It is also possible to have information on the starting digit and the ending digit of the continuous space column by updating to the digit of.

In the above description, the case where the digits of the start point and the end point of the numerical data range specified by the user match the digits of the space column is described as an example, but the present invention is not limited to this. For example, as a starting point, all digits of the data column to be processed,
And, specify any digit of all the space digits connected to the front of the data column, and as the end point, all the digits of the target data column, the next space digit of the data column, and the head connected to the front of the data column An arbitrary digit of all the space digits except the space digit may be specified. However, if the specification of such a numerical data range is permitted, the start and end points of the numerical data range specified by the user are rounded,
It is necessary to change the start point and the end point used in the processing shown in the flowchart of FIG. This rounding process can be performed by detecting a space column using the same algorithm as in FIG.

For example, the rounding process of the starting point specified by the user is performed as follows. First, the starting digit is set as a check digit, and it is checked whether or not the check digit is a space column (the range of the line is from the user-specified starting point line position to the ending point line position). If it is not a space column, the check digit is returned to the previous digit, and the same check is performed. This operation is continued until a space column is detected. Then, the digit of the space column detected first is set as the digit of the starting point after rounding.

On the other hand, rounding processing of the end point specified by the user is performed as follows. First, the digit at the end point is set as a check digit, and it is checked whether or not the check digit is a space column (the range of a row is from the row position of the start point specified by the user to the row position of the end point). If the first check digit is not a space column, advance the check digit to the next digit and perform a similar check. This operation is continued until a space column is detected. Then, the digit of the space column detected first is set as the digit of the end point after rounding. On the other hand, if the first check digit is a space column, the check digit is returned to the previous digit, and if this new check digit is not a space column, the first check digit is set as the end point digit after rounding. If the digit before the first check digit is also a space column, the digits after the first check digit are checked in order, the first non-space digit is detected as the space column, and that digit is rounded. The last digit of the end point.

Further, when the start point of the numerical data range is designated and input, the entire data field including the start point position specified by the user can be extracted by the same algorithm and, for example, can be highlighted. Similarly, at the time of specifying and inputting the end point of the numerical data range, it is also possible to extract the entire data column including the end point position specified by the user and display it in reverse video.

[0037]

As described above in detail, according to the present invention, the table format (table format data) is structured such that the data column is divided by a blank column in which all the same digits are blank and a row boundary. When a numeric data range to be graphed for a table format with a simple structure is specified, a blank column is detected for each digit from the table format within the specified range. Even when, the division boundary (vertical division boundary) at the time of dividing into the data string to be graphed can be obtained, and the tabular numerical data group within the specified range is sandwiched by the detected blank columns. Can be divided into data strings for each area that does not include a blank string.

That is, according to the present invention, even if tabular data in which numerical data that can be graphed is set without using ruled lines, data division boundaries can be easily identified,
Division into data strings can be performed correctly.
