Problems solved by technology

Using this scheme to draw a trend graph, when the amount of collected data is large enough, a large-capacity memory is often required to store all the collected data; this is difficult to achieve in some application scenarios
In addition, when the changing range of the relevant conditions of the collected data gradually increases, the length of the resulting trend graph will increase accordingly, and it is difficult to display all the information in the trend graph at one time on a limited-scale display device

Abstract

The invention discloses a trend chart dynamic generation method, electronic measurement equipment and a storage medium, and the method comprises the steps: dividing a time axis of a display interface into a plurality of time periods, and determining the display data volume of the display interface and the first data volume of each time period; obtaining a current data volume in the memory and a second data volume corresponding to each time period; if the display data volume is smaller than the current data volume of the memory, according to the difference value between the second data volume and the first data volume in each time period, determining a time period for executing a deletion operation and executing the deletion operation, so that the residual data volume of the deleted memory is equal to the display data volume; and finally, drawing trend image data according to the deleted residual data of the memory. When the current data volume in the memory exceeds the display data volume, the data in the partial time period can be compressed according to the timeline type, so that the data volume displayed in the display interface is kept unchanged, and data compression and dynamic generation of the trend chart are realized.

Description

technical field [0001] The invention relates to the field of data visualization analysis, in particular to a dynamic generation method of a trend graph, an electronic measuring device and a storage medium. Background technique [0002] In the field of data visualization analysis, trend graphs can be used to visually show the changing trend of data when a certain relevant condition changes continuously. Usually, the trend graph is used to represent the change trend of data over time; in some applications that require high real-time data, the trend graph is often updated in real time with the new data collected, and the dynamically generated trend graph can reflect the data in a timely manner The latest changes to provide a reliable basis for data analysis and related decision-making. The trend graph usually takes the relevant conditions of the collected data as the abscissa, and the amplitude of the collected data as the ordinate; the amplitude of the collected data is regar...
