Embodiment Construction

[0034] Please refer to the attached figure 1 , with figure 1 A schematic flowchart of the Echart-based line display method provided by the embodiment of the present application is shown. attached by figure 1 It can be seen that the Echart-based line display method provided in the embodiment of the present application specifically includes:

[0035] S01: Use BMap to initialize the map, so that the map only shows the outline of each province.

[0036] Bmap map is a third-party map application that can switch between the data sources of Baidu map and Gaode map. In the embodiment of this application, the BMap is used to initialize the map. Specifically, in order to avoid the interference of other data such as the display of non-domestic place names and the display of railway lines on the map, it is necessary to hide the above data so as to only display the distribution outline map of each province in my country.

[0037] S02: Determine the stay level according to the zoom lev...

Abstract

The invention provides an Echart-based line display method. The method includes: adopting BMap to initialize a map, and determining stay level according to zooming grade of the map; marking coordinates of the provincial capital, cities and counties of each province in the map according to an Echart to generate province data; drawing and displaying lines according to lines type in the Echart and the province data. In the method, BMap is adopted to draw a map background to realize map initialization, the stay level is determined according to the zooming grade of the map, the coordinates of the provincial capital, the cities and the counties of each province are marked on the initialized map by adopting the Echart, in this way, drawing, displaying and differentiating of lines different in running transport capacity and stay points are realized through different colors so as to visually display running direction of the lines, and respective data can be displayed separately when loops appear.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an Echart-based line display method. Background technique [0002] With the development of transportation, tourism, transportation, etc., maps have increasingly become the main tool for people's daily life, work, and travel. For transportation and other aspects, the visual display of various routes and stop points on the map is particularly important. [0003] Usually, different colors are used on the map to reflect the capacity of each line and the number of stays at the stop points. At the same time, the track of the line also clearly shows the running direction of the vehicle, so as to reflect the visual display of each route and stop points . For the same line between two cities, in order to allocate vehicles reasonably and maximize the utilization of the line, it is necessary to clearly distinguish the outgoing road and the return road. Therefore, it is necessary to use ...
