hoverDotRadiusOffset property

Map<String, double> hoverDotRadiusOffset
getter/setter pair

Hover dot area radius offset. By default the hover dot area is equal to the dot point area size. Just to remind you, dot point is each point in the graph that represents a data point.

You may want to increase the hover area if you feel that the dot point is too small to hover, but don't want to increase the dot point size.

Implementation

Map<String, double> hoverDotRadiusOffset = const {};
