showCrosshairLabel property

bool showCrosshairLabel
final

Whether to show a crosshair Y-value label positioned over this axis.

When enabled in multi-axis normalized mode, displays the actual (denormalized) Y-value at the crosshair's horizontal position, drawn with a semi-transparent background over this specific Y-axis.

This is useful in multi-axis charts where the default crosshair Y-label shows normalized percentages which are not meaningful to users.

Example:

YAxisConfig(
  id: 'power_axis',
  position: YAxisPosition.left,
  showCrosshairLabel: true, // Shows actual power value on crosshair
)

Defaults to false.

Implementation

final bool showCrosshairLabel;
