HorizontalLineAnnotation cannot display full value

[Hung Nguyen]

Hi, pls help me to find the way to show full value on this kind of Annotation on Y-Axis.

The value should be 1.2101, but it always displays as 2 decimal

<syncfusion:HorizontalLineAnnotation  

                    Name="CurrentPrice" 

                    ShowAxisLabel="True" 

                    HorizontalTextAlignment="Center"

                    >

this.CurrentPrice.Y1 = Convert.ToDecimal("1.2101");

Hi Hung, 

 

Thanks for contacting Syncfusion Support. 

 

We have analyzed the reported problem (axis label in annotation displaying with 2 decimal precision always) since we have internally round off the corresponding axis value with 2 decimal precision. However, we can resolve this problem by binding actual axis value directly to the Text in TextBlock of AxisLabeltemplate . Please refer the below codes, 

 

Code Snippet[XAML] 

 

<chart:SfChart.Annotations> 

      <chart:HorizontalLineAnnotation   

                    Name="CurrentPrice"  

                    ShowAxisLabel="True"  

                    Y1="1.2101" 

                    HorizontalTextAlignment="Center" 

                    > 

                    <chart:HorizontalLineAnnotation.AxisLabelTemplate> 

                        <DataTemplate> 

                            <Border   CornerRadius="2"> 

                                <Grid Background="#1E90FF" Width="40"  MinHeight="20"> 

                                    <TextBlock Text="{Binding Y1, ElementName=CurrentPrice}" Padding="2" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White"></TextBlock> 

                                </Grid> 

                            </Border> 

                        </DataTemplate> 

                    </chart:HorizontalLineAnnotation.AxisLabelTemplate> 

       </chart:HorizontalLineAnnotation> 

</chart:SfChart.Annotations> 

 

Please find the output screenshot below,
