Choose the tooltip behavior in cases when there is an empty value in a series or a column in the Tooltip Content field.

• Off (default): The tooltip will always display all series and Tooltip Content columns. If they have empty values, the tooltip will display (Blank).
• On: If a series or a column from the Tooltip Content field has an empty value, it will be omitted from the tooltip entirely. If there is no data in any series or Tooltip Content columns, the tooltip will display a No Data message which can be customized with the Empty Tooltip Text property.
