ScatterTouchTooltipData class

Holds representation data for showing tooltip popup on top of spots.

Constructors

ScatterTouchTooltipData({double? tooltipRoundedRadius, EdgeInsets? tooltipPadding, FLHorizontalAlignment? tooltipHorizontalAlignment, double? tooltipHorizontalOffset, double? maxContentWidth, GetScatterTooltipItems? getTooltipItems, bool? fitInsideHorizontally, bool? fitInsideVertically, double? rotateAngle, BorderSide? tooltipBorder, GetScatterTooltipColor? getTooltipColor})

if ScatterTouchData.handleBuiltInTouches is true, ScatterChart shows a tooltip popup on top of spots automatically when touch happens, otherwise you can show it manually using ScatterChartData.showingTooltipIndicators. Tooltip shows on top of spots, with getTooltipColor as a background color, and you can set corner radius using tooltipRoundedRadius. If you want to have a padding inside the tooltip, fill tooltipPadding. Content of the tooltip will provide using getTooltipItems callback, you can override it and pass your custom data to show in the tooltip. You can restrict the tooltip's width using maxContentWidth. Sometimes, ScatterChart shows the tooltip outside of the chart, you can set fitInsideHorizontally true to force it to shift inside the chart horizontally, also you can set fitInsideVertically true to force it to shift inside the chart vertically.
