Statistical Chart Dynamic Data Volume Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information devices, such as smartphones and tablets, fail to dynamically adjust the data volume of statistical charts when switching between portrait and landscape orientations, leading to suboptimal screen utilization due to the inability to fully utilize the changed screen size.
Innovation Solution
A method and apparatus that determine screen rotation events to adjust the data volume by obtaining additional data when switching from portrait to landscape orientation, allowing the statistical chart to fill the larger drawing area, with the landscape orientation drawing area's width equal to the screen height, and displaying the chart in this new area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal displays a statistical chart in portrait orientation, then the chart can be displayed, but the screen utilization is low when switching to landscape orientation because the data volume cannot be dynamically adjusted
Solution Approach 1:
The patent implements dynamic adjustment of data volume based on screen orientation. When the screen rotates from portrait to landscape orientation, the system automatically increases the data volume to be displayed in the statistical chart, utilizing the additional horizontal space. This dynamic adaptation resolves the contradiction by making the display system flexible rather than fixed, allowing full screen utilization in both orientations without requiring complex manual intervention.
Solution Approach 2:
The system changes the parameter of data volume according to the screen orientation state. In portrait orientation, a smaller data volume is displayed, while in landscape orientation, a larger data volume is displayed. This parameter change approach allows the statistical chart to adapt to different screen dimensions, improving screen utilization without adding significant system complexity.
2Area of stationary object
If the terminal switches from portrait to landscape orientation, then more screen space is available, but the existing system cannot use this additional space effectively
Solution Approach 1:
The patent utilizes the additional horizontal dimension provided by landscape orientation to display more data points in the statistical chart. By detecting the orientation change and adjusting the data volume accordingly, the system transforms the unused horizontal space into valuable information display area, effectively converting the dimensional advantage of landscape mode into increased information density without compromising chart readability.

AI summary
A method and an apparatus for displaying a statistical chart. The method includes determining whether a screen rotation event of switching from portrait-orientation display to landscape-orientation display is received. The method further includes obtaining additional to-be-shown data added during switch from a portrait-orientation-display drawing area to a landscape-orientation-display drawing area if yes, and drawing the landscape-orientation-display drawing area. The method further includes displaying a statistical chart in the drawn landscape-orientation-display drawing area, where the additional to-be-shown data is shown in the statistical chart. A statistical chart fills a drawing area in a landscape-orientation state.
