Create tooltip with crosshair object

[Bar Ilan]

Hi, Can u provide example on how to create in painter the following tooltip:

I am using a CustomCrosshair class that extends CrosshairBehavior, and I want to implement it inside the overridden onPaint method.

Hi Bar,

By using Custom CrosshairBehavior, you can be able to customize the cross-hair line and tooltip text in the axis only and it is not possible to display the tooltip inside the Plot Area. To achieve your outcome, you can customize the appearance of the tooltip by using the builder in the TooltipBehavior. Also, you can hide the background color and nose for the tooltip by setting the color to Colors.Transparent in the TooltipBehavior. We have provided a code snippet, user guide documentation link, and online sample link for your reference.

Code Snippet:

  tooltipBehavior: TooltipBehavior(

enable: true,

color:Colors.transparent,

builder: (data, point, series, pointIndex, seriesIndex) {

// you can customize the tooltip text here

return Text(

point.y.toString(),

            );

          },

        ),
