I change the tooltip using a tag, but there is a problem: the text does not fit, how can I change the width and height and also change the color in the tooltip? i tried to bind tooltip but it doesnt work, also i checked Oxyplot Documentation but dont find anything.

            var series1 = new ScatterSeries
            {
                MarkerType = MarkerType.Circle,
                MarkerSize = 3,
                MarkerFill = OxyColors.Gold,
                MarkerStrokeThickness = 2,
                YAxisKey = "YAxis2",
                TrackerFormatString = "{Tag}"
            };

upd: i solve it

<oxy:PlotView Model="{Binding MyModel}"
              HorizontalAlignment="Stretch"
              Height="300"
              Background="Transparent">
    <oxy:PlotView.DefaultTrackerTemplate>
        <ControlTemplate>
            <oxy:TrackerControl Position="{Binding Position}" LineExtents="{Binding MyModel.PlotArea}">
                <oxy:TrackerControl.Background>
                    <SolidColorBrush Color="#C0000000" />
                </oxy:TrackerControl.Background>
                <oxy:TrackerControl.Content>
                    <Border Background="Transparent" Padding="5">
                        <TextBlock Text="{Binding}" Margin="7" Foreground="#d1d0c5"/>
                    </Border>
                </oxy:TrackerControl.Content>
