Graph viewer

A method of displaying data, the method comprising:

• providing a graphical user interface for display on a user terminal, wherein the graphical user interface comprises:
• a first graph of a first portion of the data,
• a second graph of a second portion of the data, the second portion of the data including the first portion of the data, and
• a first sliding tool and a second sliding tool displayed on the second graph and configured such that a user can move the first and second sliding tools relative to each other and relative to the second graph to increase or decrease the amount of the data displayed by the first graph;
• receiving an electronic communication from the user terminal indicating that a user moved the first and second sliding tools relative to each other and relative to the second graph;
• and
• using a processor to increase or decrease the amount of the data displayed by the first graph based on the user's movement of the first and second sliding tools relative to each other and relative to the second graph.

A computer program product comprising a computer-readable medium, the computer-readable medium comprising computer-executable program code stored therein, the computer-executable program code comprising:

• a first computer-executable code portion configured to provide a graphical user interface comprising:
• a first graph of a first portion of the data,
• a second graph of a second portion of the data, the second portion of the data including the first portion of the data, and
• a first sliding tool and a second sliding tool displayed on the second graph and configured such that a user can move the first and second sliding tools relative to each other and relative to the second graph to increase or decrease the amount of the data displayed by the first graph;
• a second computer-executable program code portion configured to receive a communication indicating that a user moved the first and second sliding tools relative to each other and relative to the second graph;
• and
• a third computer-executable program code portion configured to increase or decrease the amount of the data displayed by the first graph based on the received communication indicating the user's movement of the first and second sliding tools.

An apparatus comprising:

• a memory having data stored therein;
• a communication interface configured to provide information to be displayed on a display device;
• and
• a processor operatively coupled to the memory and the communication interface and configured to use the communication interface to provide a graphical user interface to be displayed on the display device, wherein the graphical user interface comprises a graph viewing tool for charting data stored in the memory, the graph viewing tool comprising:
• a first graph of a first portion of the data;
• a second graph of a second portion of the data, the second portion of the data including the first portion of the data;
• and
• a selection tool displayed on the second graph and configured to allow a user to select a portion of the second graph and thereby define the data displayed by the first graph.
