Scatter Diagram Display for Surface Analysis Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In phase analysis using surface analyzers, determining the correlation between multiple elements from a large number of scatter diagrams displayed in a matrix can be difficult, requiring repeated rearrangement to identify meaningful correlations.
Innovation Solution
A scatter diagram display device that performs principal component analysis on elemental map data, sets priority levels for elements based on analysis results, and arranges scatter diagrams accordingly to facilitate easy determination of correlations, or calculates variance of scatter diagrams to prioritize their display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large number of scatter diagrams are displayed in a matrix to show correlations between multiple elements, then the completeness of information is improved, but the ease of operation deteriorates because it becomes difficult to determine correlations depending on arrangement
Solution Approach 1:
The patent changes the arrangement parameter of scatter diagrams from arbitrary or fixed matrix positions to positions determined by calculated priority levels. By computing priority values based on the number of undetermined correlation relationships for each element, the system dynamically repositions scatter diagrams to optimize visibility of important correlations while maintaining complete information display.
2Device complexity
If scatter diagrams are arranged in a fixed matrix format, then the device complexity is reduced, but the productivity deteriorates because analysts must repeatedly rearrange diagrams to identify correlations
Solution Approach 1:
The patent performs preliminary calculation of priority levels for all elements before displaying scatter diagrams. By pre-computing the number of undetermined correlation relationships for each element and using these values to determine optimal display positions, the system eliminates the need for repeated manual rearrangement during analysis, thereby improving productivity while maintaining system simplicity.

AI summary
A scatter diagram display device includes a principal component analysis section that performs principal component analysis on intensity or concentration map data that represents each element, a priority level setting section that sets a priority level to each element based on the results of the principal component analysis performed by the principal component analysis section, and a display control section that performs a control process that arranges a plurality of scatter diagrams generated by combining each element based on the priority level that has been set to each element by the priority level setting section, and displays the plurality of scatter diagrams on a display section.
