Method and device for data complementation based on time tendency graph

Abstract

The invention discloses a method and a device for data complementation based on time tendency graphs, and relates to the technical field of data process. Main objectives of the invention are to improve accuracy of tendency graph reflected index data with time changing trends through complementing index data corresponding to time. The main technical scheme comprises: obtaining time periods and unitinterval required by generating a time tendency graph, the unit interval being positive integer times of minimum time interval for labeling index data; according to the unit interval, analyzing the time periods, to obtain a point-in-time sequence formed by start time and end time of the time periods, and at least a trend point-in-time data divided by the unit interval; according to the point-in-time sequence, searching the index data corresponding to trend point-in-time; for the trend point-in-time which has not searched the index data, setting an index data value of the trend point-in-time as a null value. The method and the device are mainly used to complement index data missing in a tendency graph.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data completion method and device based on a time trend graph. Background technique [0002] A trend chart, also known as a trend chart, is used to display indicator data obtained within a certain time interval (such as a day, a week, or a month). It is a graph drawn with the value of the indicator data on the vertical axis and time on the horizontal axis. Trend chart is a very intuitive data visualization chart, which is widely used in data display in the interface. [0003] At present, when the interface display terminal displays the trend graph, the displayed time interval is generally set by the user through the interface display terminal, and the interface display terminal obtains the index data corresponding to the time period from the data terminal according to the set time period , resulting in a trend graph. However, when the interface display terminal acqui...

Problems solved by technology

However, when the interface display terminal acquires indicator data from the data terminal, the required indicator data is a set of continuous indicator data corresponding to the time period. However, the data terminal generally only Save the indicator data, and mark the corresponding time data on the indicator data, instead of continuously recording the indicator data according to the unit time interval. Playing time, the number of playing times in a certain hour is counted and recorded, and if there is no playing in a certain hour, it will not be recorded

This leads to the incoherence of the indicator data obtained by the interface display terminal, and when generating the trend graph, these time points without indicator data will be ignored, or the indicator data corresponding to the time point will be corresponding to its previous an...
