customize adornments with another Y value

[Claudio]

Hi!

I am used a class with three attribute: date, a numeric value and a description of this value (string).

I would obtain a SfChart (LineSeries) with date in x axis, numeric value in y axis and description of this value as adorment.

I have obtained the Line Series with date and numeric value, my problem is assign the description at adornment.

Can you help me?

Query: How to set the description for adornments?
 
We can achieve your requirement using LabelTemplate property in ChartAdornmentInfo, is used to customize the adornment labels as shown in the below code snippet.
 

[XAML]
                <chart:LineSeries XBindingPath="Year" YBindingPath="India" ItemsSource="{Binding  DataPoints}" >
                <chart:LineSeries.AdornmentsInfo>
                    <chart:ChartAdornmentInfo ShowLabel="True" Symbol="Ellipse"  SegmentLabelContent="LabelContentPath" ShowMarker="True">
                        <chart:ChartAdornmentInfo.LabelTemplate>
                            <DataTemplate>
                                <TextBlock FontSize="12" Foreground="White"
                           Margin="5" Text="{Binding Path=Item.Description}"/>
                            </DataTemplate>
                        </chart:ChartAdornmentInfo.LabelTemplate>
                    </chart:ChartAdornmentInfo>
                </chart:LineSeries.AdornmentsInfo>
 

 
Here ‘Item’ represents the underlying object, from that we can get required property.
 
You can get the output as shown in the below image.
