Abstract

A data processing apparatus and method are provided. A first pie chart graphic is generated from first node data of a first node among hierarchical data and is displayed on a display. A processor analyzes an input to determine second node data of a second node that is an access target among the hierarchical data. A second pie chart graphic is generated from the second node data.

Claims

1. A data processing apparatus, comprising:

a storage unit configured to store hierarchical data;

a display unit configured to display a first pie chart graphic that is generated from first node data of a first node among the hierarchical data; and

a processor configured to;

analyze a pointing input to determine second node data of a second node that is an access target among the hierarchical data; and

generate a second pie chart graphic from the second node data.

2. The apparatus of claim 1, wherein the pointing input corresponds to a touch input.

3. The apparatus of claim 1, wherein the first pie chart graphic comprises at least one of parent node information of the first node and sibling node information of the first node.

4. The apparatus of claim 3, wherein, in response to the display unit displaying the first pie chart graphic, the display unit is further configured to display context information associated with the first node and a node of which information is included in the first pie chart graphic.

5. The apparatus of claim 2, wherein:

in response to the touch input corresponding to a drag, the processor is further configured to analyze a direction of the drag to determine a sibling node of the first node as the second node;

in response to the touch input not corresponding to the drag, the processor is further configured to analyze a touch input point to determine any one of a parent node of the first node and a child node of the first node as the second node; and

the processor is further configured to generate the second pie chart graphic from the determined second node data.

6. The apparatus of claim 1, wherein the second pie chart graphic comprises at least one of parent node information of the second node and sibling node information of the second node.

7. The apparatus of claim 6, wherein the display unit is further configured to convert the first pie chart graphic to the second pie chart graphic generated by the processor to display the converted second pie chart graphic.

8. The apparatus of claim 7, wherein, in response to the display unit displaying the second pie chart graphic, the display unit is further configured to display context information associated with the second node and a node of which information is included in the second pie chart graphic.

9. The apparatus of claim 8, wherein, in response to the pointing input being received in a point corresponding to a third node among the displayed context information, the processor is further configured to:

determine the third node as the second node that is the access target; and

generate the second pie chart graphic from the second node data.

10. The apparatus of claim 1, wherein the hierarchical data corresponds to schedule data used in a personal schedule management program.

11. The apparatus of claim 10, wherein the display unit is further configured to display an indicator indicating a current time together with the first pie chart graphic that is generated from the first node data.

12. The apparatus of claim 10, wherein the display unit is further configured to display context information associated with the first node together with the first pie chart graphic that is generated from the first node data.

13. The apparatus of claim 1, wherein:

the display unit is further configured to display a first graphic area, corresponding to a parent node of the first node, around the first pie chart graphic, and

in response to the pointing input corresponding to a drag input starting from the first graphic area, the processor is further configured to;

determine a sibling node of the first node as the second node that is an access target; and

generate the second pie chart graphic from the second node data.

14. The apparatus of claim 13, wherein:

the display unit is further configured to display a second graphic area, corresponding to a grandparent node of the first node, around the first graphic area, and

in response to the pointing input corresponding to the drag input starting from the second graphic area, the processor is further configured to;

determine any one of child nodes of the sibling node of the grandparent node of the first target as the second node that is the access target; and

generate the second pie chart graphic from the second node data.

15. A data processing method, comprising:

generating a first pie chart graphic from first node data of a first node among hierarchical data to display the first pie chart graphic;

analyzing a touch input detected via a touch panel to determine second node data of a second node that is an access target among the hierarchical data, and to access the second node data; and

generating a second pie chart graphic from the second node data to display the second pie chart graphic.

16. The method of claim 15, wherein the generating and the displaying of the first pie chart graphic comprises:

retrieving a sibling node of the first node by referring to parent node information of the first node;

generating the first pie chart graphic by combining child node information of the first node with at least one of parent node information of the first node and sibling node information of the first node; and

displaying the first pie chart graphic.

17. The method of claim 15, wherein the generating and the displaying of the first pie chart graphic comprises displaying context information associated with the first node and at least one node that is generated into the first pie chart graphic and is displayed together with the first node.

18. The method of claim 16, wherein the analyzing, the determining, and the accessing comprises:

analyzing a drag direction to determine a sibling node of the first node as the second node, where the detected touch input correspond to a drag input;

analyzing a touch input point to determine any one of a parent node of the first node and a child node of the first node as the second node; and

accessing the second node data stored in a database to read the second node data from the database.

19. The method of claim 16, wherein the displaying and the generating of the second pie chart graphic comprises:

retrieving a sibling node of the second node by referring to parent node information of the second node;

generating the second pie chart graphic by combining child node information of the first node with at least one of parent node information of the second node and sibling node information of the second node; and

displaying the second pie chart graphic.

20. A non-transitory computer-readable recording medium storing a program for implementing a data processing method, comprising:

generating a first pie chart graphic from first node data of a first node among hierarchical data to display the first pie chart graphic;

analyzing a touch input detected via a touch panel to determine second node data of a second node that is an access target among the hierarchical data, and to access the second node data; and

generating a second pie chart graphic from the second node data to display the second pie chart graphic.
