LabelingFunction
is an option for data visualization functions to automatically label elements of a visualization.
Details
- LabelingFunction->f specifies that each chart element should have a label given by f[value,index,lbls], where value is the data value associated with the element, index is its position in the nested list of datasets, and lbls is the list of relevant labels.
- LabelingFunction->None specifies that no labeling should be done.
- LabelingFunction->pos places the default labels at position pos, such as Top , Bottom , Left , Right .
- A setting of Automatic will automatically place labels depending on the type of plot or chart.
- If the labeling function f returns a labeling expression expr not of the form Placed […], the labeling expression is taken to be Placed [f[…],Automatic ].
- Labels in a particular chart can be specified by ChartLabels , LabelingFunction , or explicit Labeled wrappers. All labels specified in all ways will be used in any given chart.

LabelingFunction uses the metadata as labels automatically:
Use the metadata as the point markers:
Use callouts to label points with their values:
Use a Panel around the values and place them above the bars:
Use automatic labeling by values through Tooltip and StatusArea :
Scope (2)
Do no labeling:
Place row, column, and value labels in a Tooltip :
