Title:
LOAD-CONTROLLABLE POINT PICKING DRAWING METHOD FOR LARGE DATA VOLUMES IN DATA ACQUISITION MONITORING SOFTWARE
Document Type and Number:
WIPO Patent Application WO/2024/087561
Kind Code:
A1
Abstract:
The present invention relates to a load-controllable point picking drawing method for large data volumes in data acquisition monitoring software, comprising: processing original sampling data in a data file; drawing a curve according to a coordinate range; determining whether to perform a graphic operation; and if yes, drawing a curve according to a new coordinate range. The drawing load can thus be controlled when drawing data in any range, and the maximum program execution time is independent of factors such as the data volume, graphic scaling, graphic movement, and coordinate range. Additionally, users of engineering graph analysis software generally pay attention to positions of abrupt change, the maximum value, or the minimum value of signals. When a computer displays a massive amount data on a single screen, how to retain all the feature values under a controllable load is a difficulty in graphic curve drawing. By rationally grouping data and drawing the maximum value and the minimum value of each group of data, the present invention ensures the display of key information in a curve graph to the maximum extent.
