Need to bind a property in a style at the point that I reference it

The style I am using contains several elements, but I will show just the horizontal line in my example code here. The StrokeDashArray of the Line is not defined defined yet.

    <Style x:Key="YAxisTitleStyle" TargetType="s:AxisTitle">
        <Setter Property="ContentTemplate">
            <Setter.Value>
                <DataTemplate>
                    <Grid>
                        <Line X2="{Binding ActualWidth, RelativeSource={RelativeSource Self}}"
                              Stroke="{Binding Path=BorderBrush, RelativeSource={RelativeSource AncestorType={x:Type s:YAxis}}}"
                              StrokeThickness="2"
                              StrokeDashArray=""/>
                    </Grid>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I want to define the StrokeDashArray at the point that I use the style.

                <YAxis TitleStyle="{StaticResource YAxisTitleStyle}"
                      BorderBrush="{Binding ElementName=HResitivitySeries, Path=SeriesColor, Converter={StaticResource ColorToBrushConverter}}"/>

I need to somehow bind the StrokeDashArray for the line in the style to the StrokeDashArray property of the HResistvitySeries. I have no idea how to do this binding, or if it is even possible. I was able to take the stroke of the line from the BorderBrush of the YAxis in order to sync the colors, but the YAxis has no property equivalent to a StrokeDashArray, and the HResistivitySeries is not an ancestor of the YAxis.
