Bad chart performance when using ChartAdornmentInfo

[James Newton King]

I have a chart with 500 items in it and it has significant performance issues. It takes about 10 seconds to render the series data to the screen. Resizing or scrolling the chart also causes a 10 second delay.

I've tracked it down to ChartAdornmentInfo. When I remove the ChartAdornmentInfo from the line series the chart becomes significantly faster.

XAML below:

<charts:SfChart Grid.Column="0" Grid.Row="1"

                AreaBorderThickness="0">

    <charts:SfChart.Behaviors>

        <charts:ChartZoomPanBehavior

            ResetOnDoubleTap="False"

            EnableMouseWheelZooming="False"

            EnableSelectionZooming="False"

            EnablePinchZooming="False"

            EnableZoomingToolBar="False"

            ZoomMode="X"

            EnablePanning="True" />

    </charts:SfChart.Behaviors>

    <charts:SfChart.PrimaryAxis>

        <charts:DateTimeCategoryAxis

            ShowGridLines="False"

            ZoomPosition="1"

            ZoomFactor="{Binding ZoomFactor}"

            LabelFormat="dd/MM/yy HH:mm"

            Interval="1"

            Style="{StaticResource ChartAxisXTextStyle}"

            LabelRotationAngle="-30"

            TickLineSize="0"

            AxisLineStyle="{StaticResource ChartAxisLineStyle}"

            FontSize="10"

            EdgeLabelsDrawingMode="Shift" />

    </charts:SfChart.PrimaryAxis>

    <charts:SfChart.SecondaryAxis>

        <charts:NumericalAxis

            ShowGridLines="False"

            Interval="1"

            Style="{StaticResource ChartAxisYTextStyle}"

            Minimum="{Binding MinYValue}"

            Maximum="{Binding MaxYValue}"

            TickLineSize="0"

            AxisLineStyle="{StaticResource ChartAxisLineStyle}">

            <charts:NumericalAxis.StripLines>

                <charts:ChartStripLine

                    Opacity="0.3"

                    Background="{StaticResource AppGreenMediumBrush}"

                    Start="{Binding StripStart}" Width="{Binding StripWidth}" />

            </charts:NumericalAxis.StripLines>

        </charts:NumericalAxis>

    </charts:SfChart.SecondaryAxis>

    <charts:AreaSeries

        ItemsSource="{Binding Observations}"

        XBindingPath="ItemDate"

        YBindingPath="Value"

        Interior="{StaticResource AppBlueMediumLightBrush}" BorderThickness="0" />

    <charts:LineSeries

        ItemsSource="{Binding Observations}"

        XBindingPath="ItemDate"

        YBindingPath="Value"

        Interior="{StaticResource AppPurpleBrush}"

        StrokeThickness="1" BorderThickness="0">

        <charts:LineSeries.AdornmentsInfo>

            <charts:ChartAdornmentInfo

                ShowMarker="True"

                Symbol="Ellipse"

                SymbolInterior="{StaticResource AppBlueMediumBrush}"

                SymbolStroke="{StaticResource AppWhiteBrush}"

                SymbolHeight="10"

                SymbolWidth="10" />

        </charts:LineSeries.AdornmentsInfo>

    </charts:LineSeries>

</charts:SfChart>
