Hi,
I have a RadChart with its SeriesOrientation="Horizontal".

Can you give me a C# code example to write a custom text above each horizontal bar?

Thanks!

Hello Nadeem,

Unfortunately RadChart does not support such functionality (positioning custom text above each bar). However, you can achieve similar functionality by setting the ChartSeries.Appearance.LabelAppearance.LabelLocation property to "Inside" and using the series items labels instead:

<telerik:RadChart ID="RadChart1" runat="server" SeriesOrientation="Horizontal"
    <Series> 
        <telerik:ChartSeries> 
            <Appearance> 
                <LabelAppearance LabelLocation="Inside"
                </LabelAppearance> 
            </Appearance> 
            <Items> 
                <telerik:ChartSeriesItem YValue="10"
                    <Label> 
                        <TextBlock Text="Custom Text"
                        </TextBlock> 
                    </Label> 
                </telerik:ChartSeriesItem> 
                <telerik:ChartSeriesItem YValue="15"
                    <Label> 
                        <TextBlock Text="Custom Text 2"
                        </TextBlock> 
                    </Label> 
                </telerik:ChartSeriesItem> 
            </Items> 
        </telerik:ChartSeries> 
    </Series> 
</telerik:RadChart>

OK. I see but there might be a problem:

What happens if the text inside a bar is too long to fit inside ? Can I make it extend outside the bar?
How can I make sure that text will always be visible over the bar color and background color?

Is not there a work-around for that?

Hello Nadeem,

Labels will not be clipped if they are too big. About visibility - you will need to manually specify a color that will have enough contrast to be readable on the background you selected.

All the best,
