HorizontalGroupHelper does not handle margin of NumericAxis well

Hi

I have multiple SciChartSurfaces aligned using the HorizontalGroupHelper. I also need to have multiple y-axes in the charts. I was hoping to use set the margin on each y-axis, but when I do, the upper axis is drawn outside the window. Is there a work-around?

Example.

    <s:SciChartSurface s:HorizontalGroupHelper.HorizontalChartGroup="group">

        <s:SciChartSurface.XAxis>
            <s:NumericAxis
                AxisAlignment="Left"
                AxisTitle="x" />
        </s:SciChartSurface.XAxis>

        <s:SciChartSurface.YAxes>
            <s:NumericAxis
                Margin="0,0,0,12"
                AxisAlignment="Top"
                AxisTitle="Left y1"
                Id="LeftY1" />
            <s:NumericAxis
                Margin="0,0,0,12"

                Id="LeftY3" />
