Example of a line connection in a marker layer
Lines can be drawn in a map layer with markers to show connections between specific markers. You can specify in which order the markers should be connected, and arrows can be added to indicate the direction.
The data table below contains wind force measures at certain "LAT" and
"LONG" coordinates during the advance of two hurricanes, Camille and Katrina.
The "RECORD_ ID" column values keep track of the chronological order of the
measures.
When you create a marker layer in the map chart, the markers are positioned at each of the provided coordinates:
To emphasize the hurricanes' advance, you can connect the markers with lines. The settings are made in the Line connection section of the visualization properties for the marker layer. The image shows the visualization properties panel but the settings are similar no matter from where you open the visualization properties.
Separate lines are drawn for the two hurricanes as specified in the topmost setting. The "RECORDED_ID" column, that lists the order of measures, is selected below Order each line by to indicate in which order the markers should be connected. The added lines result in curves that show how each hurricane moves.
As shown, line connections can be used to visualize movements.
Another use of line connections could be to show routes between destinations.
