Configures the tile labels.
Each tile or the header of a group contains a text label identifying what this tile or group represents. You can change the font of tile labels or their visibility using the fields of the tile.label object. The same properties of group labels can be changed using the group.label object.
To customize a specific label, use the customize(options) method of the node to which the label belongs.
- labelField - specifies the data source field that provides texts for tile and group labels.
