Label Formatter with DateTimeContinuousAxis

[Maxence]

How to use Label Formatter with DateTimeContinuousAxis ?

 

I've tried something like that : 

<telerikChart:RadCartesianChart.HorizontalAxis>
                <telerikChart:DateTimeContinuousAxis GapLength="0.5" LabelFormatter="{Binding DateLabelFormatter}" PlotMode="BetweenTicks" MajorStepUnit="Day" MajorStep="1" />
          </telerikChart:RadCartesianChart.HorizontalAxis>

 

with my formatter just like that :

    public class DateLabelFormatter : LabelFormatterBase<DateTime>
    {
        public override string FormatTypedValue(DateTime value)
        {
            DateTimeFormatInfo dateTimeFormats = new CultureInfo("fr-FR").DateTimeFormat;
            return value.ToString("ddd", dateTimeFormats).ToUpper();
        }
    }

 

But nothing work, please I need some help ...

Hi Maxence,

You will need to add the DateLabelFormatter to the Resources section of the ContentPage and reference it as a StaticResource instead, please check the following snippet:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
           ...>
    <ContentPage.Resources>
        <ResourceDictionary>
            <local:DateLabelFormatter x:Key="DateLabelFormatter" />
        </ResourceDictionary>
    </ContentPage.Resources>
    ...

and inside the Chart definition:

<telerikChart:RadCartesianChart.HorizontalAxis>
    <telerikChart:DateTimeContinuousAxis GapLength="0.5" LabelFormatter="{StaticResource DateLabelFormatter}" PlotMode="BetweenTicks" MajorStepUnit="Day" MajorStep="1" />
</telerikChart:RadCartesianChart.HorizontalAxis>

I hope this will be helpful.
