Change EmptyPoint Label

[Washington Morais]

Hi, 

How to change the label only for EmptyDataPoints and how to define a value for this points?

I don't want to use the Average value since I don't want the dynamic column height. I want to define a custom height and a custom label for this points.

Tnks.

Hi Morais,

Thanks for your update.

We are able to apply the custom label for empty point segment by using adornment LabelTemplate with converter as shown in the below code snippet.

Code snippet:

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

var val = value as ChartAdornment;

if (double.IsNaN(val.YData))

return "Custom";

return val.YData;
}

We have prepared a sample based on your requirements and please find the sample in the following location.
