The location history chart displays the historical movements of objects against the background objects configured in the OBJECT PLACEMENT workspace.

The query used must have results called “from” and “to”, which are the start and end times for an object being at a given location. The case of these result fields is significant. Without these query result columns, the location history chart will not link points together, nor will it size points depending on how long the object was located at each point.

When defining the chart, select the name of each object as the "X" column, the points column as the "Y" column, and the "from" column as the "Z" column.
