Interface ChartTooltipOptions

'click': a click on a hovered item pins the tooltip (hover stops following the pointer); the next click, a press outside the canvas, Escape (canvas focused), wheel / pan, or a new chart unpins it. The pinned tooltip element gets data-pinned="true". Default: off

Line / area / stacked bar charts: true (default) lists every series at the hovered x / category; false only the item closest to the pointer (the GPU markers are unchanged; use hover: { mode: 'nearest' } for single-point markers too)

Row order by value: 'asc', 'desc' (NaN last), or 'none' = series order (default)

Values in the default tooltip (series values, totals, OHLC, cell / slice / box values, scatter y): a spec ('.2f', '$,.0f', { maximumFractionDigits: 1 }; see chart-format.ts) or a function. Default: the y axis format where the chart uses it, else a locale number.
