VERBOSE: Shows all the chart’s plotted series in the hover tooltip.
CONCISE: Shows only the plotted series within the row currently being hovered.
MULTI_ROW_CONCISE: Show separate tooltips for each row, where each shows the series plotted in that row.
SINGLE: Shows only the plotted series closest to/under the cursor.
NONE: Hides the tooltip entirely (also affects tooltips for other chart types).
