Labels in different map types

Labels can be used in any map type to identify and describe the markers, pies, or interactive shapes. Most settings related to labels are defined in the Labels page of the Map Chart Properties. In maps with markers or pies, you can click on a label to mark the corresponding marker, and mouseover a label to highlight both the label and the marker. In a map with a large amount of labels it can sometimes be useful to move the labels to other positions to make sure as many of the labels as possible are visible. This is done using drag and drop, and works slightly differently depending on the map type, as described below. In maps with interactive shapes, you can hover with the mouse pointer over a map shape to view its corresponding label if the label is hidden due to lack of space.

To add labels to a map chart:

Right-click in the visualization to display the pop-up menu and select Properties.

Response: The Properties dialog is displayed.
Go to the Labels page.
Select the column to Label by.

Response: Labels are displayed in the map.

Comment: When a map with interactive shapes is used, the column to label by must always come from the same data table as the column to color by. The data table used for coloring is specified on the Data page.
Specify whether to Show labels for All, Marked rows or None.

Comment: If the map chart uses markers or pies you can change the Max number of labels, or select one or more of the check boxes to Center labels on items or Show empty labels. You can also specify Display options and get content from an image column, another source or apply some kind of transformation (if any transformations are available).

To move labels in a map chart with interactive shapes:

Right-click in the visualization to display the pop-up menu and select Edit Label Positions.

Response: The label editing is enabled.
Click on the label you wish to move and drag it to its new position.
When you are done, right-click on the visualization and select Edit Label Positions again to leave the label editing mode.

Comment: You can get all original label positions back by right-clicking and selecting Reset Label Positions.

To move labels in a map with markers or pies:

Click on the label you wish to move and drag it to a new position.
Response: The label is moved to the new position.

Comment: You can get all original label positions back by right-clicking and selecting Reset Label Positions.

Comment: When tiled markers are used, labels cannot be moved to other positions since they are always centered and displayed directly on the markers.
