Hello Carlos,

You can modify the visibility and the format of the labels by using the HorizontalAxisVisibility, HorizontalAxisLabel, VerticalAxisVisibility, and VerticalAxisLabel properties of the XamSparkline. To find out more information on using these properties please see http://help.infragistics.com/doc/WPF/2015.2/CLR4.0/?page=xamSparkline_xamSparkline_Property_Reference.html.

If you would like to further customize the axis and labels you can use a style targeting either the HorizontalAxisView (for the horizontal axis and labels) or the VerticalAxisView (for the vertical axis and labels). These controls are used to draw a one-sided border for the axis which contains a content presenter housing the text blocks for the labels. Here is an example using this approach:

  <ig:XamSparkline ItemsSource="{Binding Data}" DisplayType="Line" ValueMemberPath="Value"

                         LabelMemberPath="Label" Brush="Red" HorizontalAxisLabel="{}{0}"

                         HorizontalAxisVisibility="Visible" VerticalAxisVisibility="Visible" >

            <ig:XamSparkline.Resources>

                <Style TargetType="{x:Type ig:HorizontalAxisView}">

                    <Setter Property="Template">

                        <Setter.Value>

                            <ControlTemplate TargetType="ig:HorizontalAxisView">

                                <Border Background="{TemplateBinding Background}" BorderBrush="AliceBlue"                                

                                        BorderThickness="0,4,0,0">

                                    <ContentPresenter x:Name="HorizontalAxisContentArea"

                                                      TextBlock.Foreground="Green" TextBlock.FontSize="40"/>

                                </Border>

                            </ControlTemplate>

                        </Setter.Value>

                    </Setter>

                </Style>

                <Style TargetType="ig:VerticalAxisView">

                    <Setter Property="Template">

                        <Setter.Value>

                            <ControlTemplate TargetType="ig:VerticalAxisView">

                                <Border Background="{TemplateBinding Background}"

                            BorderBrush="Pink"

                            BorderThickness="0,0,1,0">

                                    <ContentPresenter x:Name="VerticalAxisContentArea"

                                                      TextBlock.Foreground="Purple" TextBlock.FontWeight="Bold" />

                                </Border>

                            </ControlTemplate>

                        </Setter.Value>

                    </Setter>

                </Style>

            </ig:XamSparkline.Resources>

        </ig:XamSparkline>  

You can find the actual styles used for the XamSparkline in C:\Program Files (x86)\Infragistics\2015.2\WPF\DefaultStyles\XamSparkline\generic.xaml
