ChartInteractionConstants class

Constants for chart interaction behavior.

These constants define the interaction zones and timing for various chart interactions. Adjust these values to fine-tune the user experience.

Example

// Use custom tap radius
final result = ChartInteractionHelper.findNearestPoint(
  tapPosition,
  dataSets,
  chartSize,
  minX, maxX, minY, maxY,
  ChartInteractionConstants.tapRadius * 1.5, // 50% larger
);
