The map component visualizes view data on a map. The map component must be connected to a view on the workboard whose Y-axis is a geographic dimension. This dimension should not contain any nesting.
The data from the grid of the connected view is displayed in the map component and when you make changes in the grid, the map component changes according to your selection. You can choose to display in the map component only a certain part of the grid data by selecting that area. This is the same as selecting grid data for a chart in a view component.
