Non-overlapping trackball tooltips not working with extra y-axis.

[Luca]

Dear team,

The trackball tooltips (still) overlap each other when TooltipDisplayMode is set to FloatAllPoints and there are more than two axes.

This is a minimal sample that recreates the issue (check screenshot to see the issue in action):

SfCartesianChart(

primaryXAxis: NumericAxis(),

primaryYAxis: NumericAxis(),

axes: <ChartAxis>[

NumericAxis(

name: 'yAxis2',

),

],

// Chart title

title: ChartTitle(text: 'Half yearly sales analysis'),

// Enable trackball

trackballBehavior: TrackballBehavior(

activationMode: ActivationMode.singleTap,

shouldAlwaysShow: true,

enable: true,

),

series: <CartesianSeries>[

LineSeries<_SalesData, double>(

dataSource: data,

xValueMapper: (_SalesData sales, _) => sales.second,

yValueMapper: (_SalesData sales, _) => sales.sales,

name: 'Sales',

),

LineSeries<_SalesData, double>(

dataSource: data,

xValueMapper: (_SalesData sales, _) => sales.second,

yValueMapper: (_SalesData sales, _) => sales.sales + 50,

name: 'Sales2',

color: Colors.red,

),

],

),

small clarification:  sales.sales + 50 should be set to whatever makes the lines close enough for the tooltips to overlap (depending on the data).

Thanks in advance!
