Improving Resolution Of Overlapping Points In Spiral Diagrams

A spiral diagram shows a sequence of points that represent models, wherein a position on the spiral indicates reliability of the model. This is particularly helpful when many different models are represented in the diagram and the models have similar positions on the spiral and cannot be easily distinguished.

The disclosed method enhances resolution of overlapping points in spiral diagrams. The method detects a group of overlapping points and graphically distributes the points for providing enhanced resolution of the overlapping points in spiral diagrams.

Animations are used to magnify the spiral diagram from an original position to an expanded position to indicate to a user that the points are being moved to make them more visible, and give a better idea of the true value. The points are kept in a sorted order and distributed along the spiral line, while minimizing error from the true position. The spiral is modified to clamp the radius values to the inner circle (the target) and the outer circle in order to ensure all values are visible and not occluding important parts of the spiral diagram.

According to embodiments of the present invention, the mean of original values regarding a group is determined and a middle point is placed at the mean for the odd case. Alternatively, the mean point can also be displaced by one half of symbol size below the mean for even cases. The remaining points are then graphically distributed

with half (rounded down) placed below the original point and half (rounded up) placed above the original point, while maintaining the sort order of the group. This process is repeated until no two groups need to be merged.

As illustrated in the figure below, the spiral diagram is modified to cl...
