Choose the tooltip behavior for the values of stacked series.

• Auto (default setting): The visual will use True for this setting.
• True: The tooltip will display cumulative values, including all prior series in the stack. The label values will align with their respective positions on the y-axis. Example – Series 2 value will show Series 1+2 values added together.
• False: Each series value will be displayed independently. Example – Series 1 label will show only Series 1 value, and Series 2 label will show only Series 2 value.
