1. Overview A track map chart is a graph that displays geolocation data from different time points in the same chart by adding a time dimension, which usually includes several latitude and longitude location points in addition to the time dimension. 2. Function 2.1 Create Track Map The track map map has certain requirements on data, and needs to bind the longitude, latitude, track map and time order data, as shown in the following figure: The track map here refers to different moving paths, defined by you, such as Beijing, Beijing-Shanghai, etc. Different trajectories have different colors when mapping. For example, if we want to count the vehicle trajectories at different time points, we need to prepare data similar to the following figure: Bind to the corresponding area in turn: The display effect is as follows: 2.2 Interaction •The background of the map can be zoomed out and zoomed in by using the mouse wheel. •Use the action buttons on the chart to pan up, down, left, right, and zoom in and out of the map. The interaction effect is shown below: 2.3 Track Setting In the right side Graphic, you can set the color of the track and the size of the track points: The color dialog box allows you to select different color schemes and customize the color of individual legends. 2.4 Map Setting In the right side Setting, you can configure the GIS map style and data coordinate system: Please refer to GIS Map for notes on configuring GIS map style. The data coordinate system can be selected from GaoDe coordinate system, Baidu coordinate system and Earth coordinate system. In order to display the track map more accurately, please select the appropriate coordinate system according to the latitude and longitude data.
