Graph Legend Dataset Selection on Touch Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with touch screen interfaces face challenges in accurately selecting data points from multiple datasets on graphs due to their small size and the difficulty in distinguishing between datasets, leading to frustrating user interactions.
Innovation Solution
A method that utilizes a legend to select a dataset, emphasizes the graphical representation of the chosen dataset, and allows users to input points on the graph to identify data values, with features like swipe gestures for navigating between data points, and a line parallel to the y-axis to determine the selected data point, ensuring only the relevant data point values are presented.

Engineering Contradiction Analysis
1Quantity of substance
If multiple datasets are displayed on a small touch screen graph, then more information is presented, but it becomes difficult for users to select and distinguish between datasets
Solution Approach 1:
The legend is divided into individual selectable elements, each representing a separate dataset. Users can tap on specific legend elements to select or deselect corresponding datasets, allowing precise control over which datasets are displayed without having to manually interact with each graph element
Solution Approach 2:
The legend serves as an intermediary interface between the user and the multiple datasets. Instead of directly interacting with the graph elements themselves, users interact with the legend elements which then control the visibility and selection state of corresponding datasets, simplifying the interaction model
2Loss of information
If all datasets are visible on the graph, then complete information is available, but user focus and accuracy in selecting specific data points deteriorates
Solution Approach 1:
The graph dynamically adjusts the visibility of datasets based on user selection through the legend. When a user selects a specific dataset via the legend, that dataset is emphasized or highlighted while other datasets can be hidden or dimmed, allowing the interface to transition between showing all data and focusing on selected data based on user needs
3Quantity of substance
If the graph displays all datasets simultaneously, then comprehensive data is shown, but the interface complexity and difficulty of interaction increases
Solution Approach 1:
The legend provides a segmented control mechanism where each dataset can be independently managed. This segmentation allows users to selectively display only the datasets they need, reducing the effective complexity of the interface while maintaining the capability to display all datasets when required
Solution Approach 2:
The legend enables users to self-manage the visibility and selection of datasets without requiring complex controls or additional steps. The legend elements automatically correspond to their respective datasets, and user interactions with the legend directly control the graph display, simplifying the overall interface

AI summary
Various arrangements for identifying and selected a data value of a dataset presented on a graph are described. The graph may be presented, wherein the graph illustrates a plurality of datasets and a legend that identifies each of the plurality of datasets. A selection of the dataset may be received via the legend of the graph. An input of a point on the graph may be received. A value of a data point from the dataset that corresponds to the input of the point on the graph may be presented.
