Shows item key in data label.
This option enables displaying the key for the data item in its label on pie
graphs. It is enabled by default because data items are normally identified by
their key value, which is especially important when the items are not in their
natural order (i.e. when the sort
option is enabled).
The three different parts of the pie graph labels are drawn on separate lines with the key at the top, then the amount in the middle and the percentage at the bottom.
For more control over the labels, see the data_label_callback
option.
