Abstract

The present invention provides a user interface mechanism for adjusting the view of two-dimensional graphical plots so users can make compromises between the amount of detail that is presented on an electronic display and the range of data that can be within immediate view. It also provides a mechanism for controlling the subset of data that will be within view on an electronic display when the entire data plot exceeds the dimensions of the display. Finally, it provides a mechanism whereby a sliding lens may be selectively positioned over various portions of a graph, allowing the viewing of the graph at a selectable magnification.

Claims

1. A system for manipulating graphical output, comprising:

(a) a storage means for storing a data structure having at least one dimension, the data structure including a plurality of data elements, each data element having at least one value for each of the at least one dimension;

(b) a video display means for displaying an image;

(c) a pointing means, responsive to a user of the graphical output analyzing system, for generating a point signal corresponding to a location on the video display means, the pointing means including a drag switch which may be activated by the user; and

(d) processing means for performing the steps of;

(i) displaying a graph on the video display means corresponding to the data elements in the data structure, wherein each dimension of the graph is displayed at a selected resolution,

(ii) receiving from the pointing means the point signal, and

(iii) responsive to the activation of the drag switch by the user, if the point signal falls on a selected one of the at least one dimension,

(1) receiving from the pointing means a new point signal, and

(2) readjusting the selected resolution of the selected one of the at least one dimension responsive to the difference in corresponding location between the new point signal and the point signal.

2. The system of claim 1, wherein the readjusting step comprises the sub-steps of:

(A) calculating a first distance between the location corresponding to the point signal and a selected reference location;

(B) calculating a second distance between the location corresponding to the new point signal and the selected reference location; and

(C) readjusting the selected resolution of the selected dimension, such that the new selected resolution is directly proportional to a ratio of the first distance to the second distance.

3. The system of claim 1, wherein the readjusting step comprises the sub-steps of:

(A) calculating a first distance between the location corresponding to the point signal and a selected reference location;

(B) calculating a second distance between the location corresponding to the new point signal and the selected reference location; and

(C) readjusting the selected resolution of the selected dimension, such that the new selected resolution is increased if the first distance is greater than the second distance, and the new selected resolution is decreased if the first distance is less than the second distance.

4. A system for manipulating graphical output, comprising:

(a) a storage means for storing a data structure having at least one dimension, the data structure including a plurality of data elements, each data element having at least one value for each of the at least one dimension;

(b) a video display means for displaying an image;

(c) a pointing means, responsive to a user of the graphical output analyzing system, for generating a point signal corresponding to a location on the video display means, the pointing means including a drag switch which may be activated by the user; and

(d) processing means for performing the steps of;

(i) displaying a graph on the video display means corresponding to the data elements in the data structure, wherein each dimension of the graph is displayed at a selected resolution,

(ii) displaying a scroll bar along a selected dimension of the graph;

(ii) receiving from the pointing means the point signal, and

(iii) responsive to the activation of the drag switch by the user, if the point signal falls on the scroll bar,

(1) receiving from the pointing means a new point signal, and

(2) readjusting the placement of the graph on the video display along the selected dimension, wherein the point of the graph corresponding to the point signal is moved to a new location on the video display corresponding to the new point signal.

5. The system of claim 4, wherein the readjusting step comprises the sub-steps of:

(A) calculating a first distance between the left of the scroll bar and the location corresponding to the point signal;

(B) calculating a second distance between the left of the scroll bar and the location corresponding to the new point signal; and

(C) readjusting the placement of the graph based upon the differences between the first distance and the second distance.

6. A system for manipulating graphical output, comprising:

(a) a storage means for storing a data structure having at least one dimension, the data structure including a plurality of data elements, each data element having at least one value for each of the at least one dimension;
