PROBLEM TO BE SOLVED: To reduce troublesomeness in changing the event to be a display object for a graph.SOLUTION: A detection unit 21 detects the designation of a time range to be included in a temporal axis in terms of the creation of a first graph intended for a first event. A button state control unit 22 stores information on the designated time range in a button state information DB 28. A request unit 23 transmits a graph display request to a graph creation device 30. A display control unit 24 displays a graph on the basis of a HTML file received from the graph creation device 30. When the detection unit 21 has received the designation to change the first event to a second event, the request unit 23 refers to the button state information DB 28, without receiving further designation of the time range, to request the display of a second graph intended for the second event within the time range designated in the creation of the first graph. |
