Chart rendering method, device and apparatus and computer readable storage medium

Abstract

The invention discloses a chart rendering method, which comprises the following steps that: firstly, a server side in the application always returns a preset data volume of sampling data at most regardless of a data request of a default maximum interval or any target interval, so that the data volume rendered by a client side each time is limited, and the situations of lagging and collapse are eliminated; when the sampling data of the non-default maximum interval is rendered, in order to enable the user to continue to execute the scaling operation, a small amount of data of the missing interval of the current display interval relative to the default maximum interval is spliced for the sampling data of the non-default maximum interval on the basis of the sampling data of the non-default maximum interval; therefore, the user can check any local data in the default maximum interval through the scaling operation. The invention further discloses a chart rendering device and apparatus and a computer readable storage medium, which have the same beneficial effects as the chart rendering method.

Description

technical field [0001] The present invention relates to the field of chart rendering, in particular to a chart rendering method, and also relates to a chart rendering method, device, equipment and computer-readable storage medium. Background technique [0002] A linear graph (such as a line graph or a column graph) can regularly present a large amount of data so that users can view and analyze data. When the client needs to view a linear graph, it can obtain a large amount of data in the target range from the server. And render the obtained data and get a linear graph, but in some cases, the total amount of data in the target range selected by the user is relatively large, if a large amount of data is directly rendered, the operation will freeze or even the interface In the case of a crash, the user experience is poor. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents...
