Pie Chart Segment Alignment via Dynamic Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to visually compare corresponding segments across two related pie charts, even when displayed side by side with similar appearances, due to their differing positions within the charts.
Innovation Solution
A computer-implemented method that receives a selection of corresponding segments and rotates at least one pie chart to display these segments at approximately the same position, allowing for direct visual comparison by aligning their positional central angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pie charts are displayed side by side with similar appearances, then visual comparison is assisted, but corresponding segments remain at different positions making comparison awkward and difficult
Solution Approach 1:
The patent applies dynamics by allowing the pie chart to rotate dynamically. The pie chart is not static but can change its orientation to align corresponding segments with reference markers, enabling users to easily compare segments across different pie charts by positioning them at the same angular location.
Solution Approach 2:
The patent changes the angular position parameter of pie chart segments by rotating the entire pie chart. This parameter change allows corresponding segments to be aligned at the same position, transforming the comparison from difficult to easy while maintaining the visual integrity of the pie chart.
2Loss of information
If corresponding segments are displayed with similar appearance, then visual comparison is assisted, but segments at different positions still make direct comparison difficult
Solution Approach 1:
The patent introduces reference markers as intermediary elements that serve as alignment targets. These markers act as mediators between the pie chart segments and the user's comparison task, providing a common reference point that makes it easy to detect and compare corresponding segments across different pie charts.
Solution Approach 2:
The patent creates equipotential conditions by aligning corresponding segments at the same angular position around the pie chart. This ensures that all comparable segments are at equivalent positions, making detection and comparison equally easy regardless of which segment is being examined.

AI summary
Techniques for dynamically displaying corresponding segments of related pie charts are implemented by a UI engine, pie chart engine, and graphics framework engine that operate in conjunction to display at least two related pie charts having a plurality of corresponding segments, receive a user selection of corresponding segments that are displayed in different positions in their respective pie charts, rotate at least one of the related pie charts, and display the related pie charts so that the corresponding segments are displayed in the same position/orientation in their respective pie charts. The computing device may also visually highlight the selected corresponding segments and execute an animation graphically displaying the rotation of the at least one related pie chart.
