图表控件chartingToolkit去除图例说明区域以及数据点的样式定义

去除图表图例说明只需重新定义chartingToolkit:Chart的LegendStyle样式：

<chartingToolkit:Chart.LegendStyle>

                <Style TargetType="visualizationToolkit:Legend">

                    <Setter Property="Width" Value="0"/>

                    <Setter Property="Height" Value="0"/>

                </Style>
</chartingToolkit:Chart.LegendStyle>

数据点样式定义（鼠标经过数据点提示信息变为小数数据点颜色变化）：

<chartingToolkit:LineSeries.DataPointStyle>

                    <Style  TargetType="chartingToolkit:LineDataPoint">

                        <Setter Property="Background" Value="#66ad00"/>

                        <Setter Property="Width" Value="4" />

                        <Setter Property="Height" Value="4" />

                        <Setter Property="Template">

                            <Setter.Value>

                                <ControlTemplate TargetType="chartingToolkit:LineDataPoint">

                                    <Grid x:Name="Root" Opacity="2">

                                            <StackPanel>

                                                <ContentControl Content="{TemplateBinding DependentValue}" 

                                            ContentStringFormat="{}{0:N1}"/>

                                            </StackPanel>

                                        </ToolTipService.ToolTip>

                                        <Ellipse RenderTransformOrigin="0.661,0.321">

                                            <Ellipse.Style>
