A method and a system for realizing complete display of a graph curve and application thereof

Abstract

The invention discloses a method and a system for realizing complete display of a graph curve and application thereof. The method is characterized by including: obtaining a data point and extracting data according to current data magnification rate and putting the data into a preset data buffer area; when receiving the chart curve display command, calculating the data points of the time needed tobe displayed according to the time axis, and then searching the data points closest to the calculated value time in the data buffer; drawing and displaying a graph curve based on the found data points. The method for realizing complete display of a chart curve of the invention can quickly and completely display chart curve under the condition of limit storage space, realizes the real-time refreshof chart curve in smaller RAM space, greatly improves the display efficiency of chart curve, and effectively improves the us experience.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method, system and application for realizing the complete display of chart curves. Background technique [0002] Although the current smart devices have become more and more powerful with the development of technology, users have higher and higher requirements for these devices. Many smart devices are limited by their display resolution, RAM, etc. based on the impact of cost and hardware. [0003] Current wearable devices such as sports watches will have a large amount of real-time exercise data that needs to be displayed in the form of chart curves, such as step frequency curves, speed curves, barometric pressure curves, temperature curves, altitude curves, heart rate curves, motion trajectories, etc. . Wearable devices are limited by their space and weight, and their RAM space is generally small. Remove the storage space occupied by other aspects of the system, the real spac...

AI Technical Summary

Problems solved by technology

Remove the storage space occupied by other aspects of the system, the real space left for the curve data is often less than 1M, and the space occupied by the motion data will increase with the delay of the motion time, resulting in insufficient memory space to store all the curve data At the same time, the current chip running speed is not high, and the curve cannot be refreshed in real time efficiently, resulting in poor user experience
