Running chart information indexing method, device and equipment

Abstract

The embodiment of the invention provides a running chart information indexing method, device and equipment. The method comprises the following steps: receiving data, storing the data in a data chain table, converting the data into coordinate points, and drawing a running chart curve; in response to a mouse triggering event, performing thread management; and starting a line segment index thread, reading the current mouse position point, screening out an index result corresponding to the current mouse position point through a line segment click test, and displaying the index result. In this way,data can be directly converted into coordinate points, a running chart curve is generated, a running chart of line segment click testing does not need to be achieved in an object mode, storage spaceand drawing time are saved, icon operation is smoother, and the burden of a system is greatly reduced. According to the method and the device, the line segment index thread is subjected to starting management through the thread linked list, so that the thread starting frequency is greatly reduced, system memory resources are saved. Meanwhile, the mouse position is not lost, and the information index of the running chart is realized through the mouse click test on the line segment.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of information indexing, and more specifically, relate to a method, device and device for indexing information of a running diagram. Background technique [0002] The running diagram is an effective means of displaying trackside information, which can intuitively reflect the arrival and departure information of trains and the running time in the section. In a sense, in addition to displaying the train arrival and departure time information, the operation line in the operation diagram is more used as an index method. The user hopes that when the mouse is close to the line segment corresponding to a certain operation interval, the Various information in the experienced time period can be quickly and detailedly prompted. Of course, if you want to be able to prompt more information on the operation diagram, such as the average speed in the interval, the number of failures, etc., you only n...

Problems solved by technology

[0004] 1. In the case of a large amount of data, it is necessary to perform a mouse click test operation on each data point object in turn. The whole process is quite time-consuming, so there will be a delay phenomenon, and real-time performance cannot be guaranteed. Use the mouse to index the data point. greatly discounted;

[0005] 2. Graphic objects in conventional controls exist in the form of horizontal rectangles. When the line segment is at an inclined position, the original range of the line segment is expanded, which may easily cause overlapping of adjacent line segment ranges, resulting in inaccurate testing. This is also Why click data points will shift when the data points are relatively dense;

In fact, there is no mouse click test function for line segments in conventional controls, and none of its functions can return the line segment index, so it is impossible to directly implement the segment index function
