Connecting map markers with lines
Use lines to connect markers on a map to show the movement of people or items from one specified location to another.
Prerequisites
Because the line connection works by row, the data should contain values that indicate the start location and values that indicate end locations. Line connections are useful for showing a connection between locations, or the flow of items or people on a map. For example, your start location could be designated as distribution center, and your end locations as stores.
Procedure
Example of connecting markers with lines
The following image shows a plan to visit, in order of location, a few of the historically interesting sites in New York State. The line connection is applied according to latitude, starting at Oyster Bay in the south and going north to Schenectady. The lines are colored red, positioned in the background, and arrows indicate the proposed direction of travel. The markers are colored by value, with labels to indicate the name of the historical site.
