WPF Bind to selected Radio Button

I have a Radiobutton group:

 <RadioButton Name="_CreateGraph" GroupName="MapOrGraph" Content="Create Graph" />
 <RadioButton Name="_CreateMap"   GroupName="MapOrGraph" Content="Create Map"   />

How do I bind the content of a label to the selected radio button's content?

e.g. the label should say Create Graph or Create Map depending on which radio box is created?

If you have only two RadioButtons, this is a quick & dirty solution:

    <Label>
        <Label.Style>
            <Style TargetType="{x:Type Label}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding IsChecked, ElementName=_CreateGraph}" Value="True">
                        <Setter Property="Content" Value="{Binding Content, ElementName=_CreateGraph}" />
                    </DataTrigger>
                    <DataTrigger Binding="{Binding IsChecked, ElementName=_CreateMap}" Value="True">
                        <Setter Property="Content" Value="{Binding Content, ElementName=_CreateMap}" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </Label.Style>
    </Label>

<Label Content="{Binding SelectedValue.Content, ElementName=list}"  />

<ListBox x:Name="list" SelectedIndex="1"  >
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem" >
                        <RadioButton GroupName="a" Content="{TemplateBinding Content}" IsChecked="{Binding IsSelected, RelativeSource={RelativeSource TemplatedParent}  }"  />
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
    <ListBoxItem>Create Graph</ListBoxItem>
    <ListBoxItem>Create Map</ListBoxItem>
</ListBox>

I think you can make it shorter than what I did.
