Abstract

A system that has a graphical user interface (GUI) that allows a user to readily define and manipulate a transform function from one attribute, such as numerical value, to another attribute that is more understandable by by the user such as color, size or location. Special two thumb slider controls provide the transform functions. The two thumbs define break points for piecewise linear transform ranges. Further, the center transform range can be manipulated as a unit to show the user what happens if the range is maintained essentially constant but the break points are varied. The aid to visualizing characteristics otherwise hidden in large data sets, such as a monthly telephone bill of a large corporation, is very beneficial.

Claims

1. An apparatus for interactively transforming data according to manipulation by a human operator, comprising:

a computer system having a pointing device and a graphical user interface;

said graphical user interface having a data display region for displaying data according to a predetermined parameter;

said graphical user interface having a slider control;

said slider control having a first range which is mapped to the length of said slider control;

said slider control also having two adjustable limits within said first range which define a second range, each of said adjustable limits being individually adjustable by the user by selecting and moving using said pointing device;

said second range mapping said predetermined parameter to a second parameter;

said second range being movable within said first range by the user by selecting and dragging said second range along said first range; and

movement of said second range changes the transform characteristics of said predetermined parameter into said second parameter.

2. The apparatus of claim 1, wherein said first parameter is a numerical quantity and said second parameter is a color.

3. The apparatus of claim 2, wherein said second range is a color spectrum.

4. The apparatus of claim 3 wherein said spectrum is the natural or rainbow spectrum.

5. The apparatus of claim 3 wherein said spectrum is the radiant energy versus temperature spectrum of iron.

6. The apparatus of claim 1, wherein said first parameter is a numerical quantity which is represented by a first shape and said second parameter is a size of a second shape similar to said first shape that is centered in said first shape and having a size that is at most equal to a size of said first shape.

7. The apparatus of claim 1, wherein said mapping is logarithmic.

8. The apparatus of claim 1, wherein said mapping is linear.

9. The apparatus of claim 1, wherein said first parameter is percentage range of a total file and said second parameter is location within said file.

10. The apparatus of claim 9, wherein said location is described by a coordinate within a display.

12. The apparatus of claim 1, wherein said second range is moved by placing a cursor under the control of a pointing device in the second range and selecting the second range for movement by movement of a switch on the pointing device and then moving the cursor along the first range under the control of said pointing device.

13. The apparatus of claim 12, wherein said pointing device is a multi-button mouse.

14. The apparatus of claim 12, wherein said pointing device is a track-ball.

11. A method for a piecewise linear mapping of data, on a graphical user interface having a data display region for displaying data according to a predetermined parameter, having a first parameter to data having a second parameter using a slider control, said method comprising the steps of:

setting an upper limit with a first thumb of said slider control;

mapping all values of said first parameter greater than said upper limit to an upper attribute;

setting a lower limit independently of said upper limit with a second thumb of said slider control;

mapping all values of said first parameter less than said lower limit to a lower attribute; and

mapping all values of said first parameter between said upper limit and said lower limit to a transform function.

15. A method for a piecewise linear mapping of data, on a graphical user interface having a data display region for displaying data according to a predetermined parameter, having a first parameter to data having a second parameter using a slider control, said method comprising the steps of:

setting an upper limit with a first thumb of said slider control;

mapping all values of said first parameter greater than said upper limit to an upper attribute;

setting a lower limit independently of said upper limit with a second thumb of said slider control;

mapping all values of said first parameter less than said lower limit to a lower attribute; and

mapping all values of said first parameter between said upper limit and said lower limit to a transform function;

wherein said transform function is a color spectrum that varies in a defined manner as said first parameter takes on values between said upper limit and said lower limit.
