# plotOptions.map.tooltip

A configuration object for the tooltip rendering of each single series. Properties are inherited from tooltip. Overridable properties are `headerFormat`, `pointFormat`, `yDecimals`, `xDateFormat`, `yPrefix` and `ySuffix`. Unlike other series, in a scatter plot the series.name by default shows in the headerFormat and point.x and point.y in the pointFormat.
