Abstract

A method and apparatus for locating a predetermined position in a computer file. A continuous, static ECG waveform is displayed in rows on a CRT screen. A scroll bar permits a user to use a computer mouse to click and drag the scroll box to display different portions of the ECG data. When the cursor is on the scroll box and a button on the mouse is depressed, a data window opens adjacent the scroll box and displays the hours, minutes and seconds of the time of day when the ECG waveform of the portion currently displayed was recorded. The data window moves with the scroll box and continues to display current time of the data displayed. When the mouse button is released, the data window closes and the screen changes to display the ECG waveform from the newly selected time.

Claims

1. A method for locating a predetermined position in a computer file comprising the steps of:

displaying a portion of the file in a window having a scroll box on one side thereof for varying which portion of the file is displayed in the window;

engaging and moving the scroll box with a cursor;

automatically opening a relatively small data window adjacent the scroll box in response to engagement and movement of the scroll box with the cursor;

displaying data in the data window indicative of a position of that portion of the file displayed within the window;

moving the scroll box thereby changing the data in the data window until said predetermined position is located; and

automatically closing said relatively small data window in response to disengagement of said scroll box with said cursor.

2. The method of claim 1 wherein said method further includes the step of moving the data window responsive to scroll box movement thereby maintaining substantially the same relative position between the scroll box and the data window.

3. The method of claim 1 wherein said computer file comprises chronological data and wherein the data in the data window comprises units of time.

4. Apparatus for locating and displaying a predetermined position in a computer file within a system having a display, said apparatus comprising:

means for displaying a portion of the file in a window having a scroll box on one side thereof for varying which portion of the file is displayed in the window;

means for engaging and moving the scroll box with a cursor;

means for automatically opening a relatively small data window adjacent the scroll box in response to engagement and movement of the scroll box with the cursor;

means for displaying data in the data window indicative of a position of that portion of the file displayed within the window;

means for moving the scroll box thereby changing the data in the data window until said predetermined position is located; and

means for automatically closing said relatively small data window in response to disengagement of said scroll box with said cursor.

5. The apparatus according to claim 4, wherein said computer file includes chronological data and wherein said means for displaying data in the data window indicative of a position of that portion of the file displayed in the window comprises means for displaying units of time.

6. The apparatus according to claim 4, further including means for moving the data window in response to movement of the scroll box thereby maintaining substantially the same relative position between the scroll box and the data window.
