on a doughnut, how do i selectively show the format?

[Jingying]

Currently i have

 

doughnutSeries.Definition =

 

new DoughnutSeriesDefinition();

 

((

 

DoughnutSeriesDefinition)doughnutSeries.Definition).LabelOffset = 0.7d;

 

doughnutSeries.Definition.DefaultFormat =

 

"#%{p0}";

And when i have 0%, the slices are just a line and the text looks messy.
Is there a way, not to show the 0% when it's 0%?

here's how it looks like now : http://tinyimages.us/show.php/16601_doughnut.JPG.html

Hello Jingying,

You can loop through all the items and remove the label:

foreach (var item in RadChart1.DefaultView.ChartArea.DataSeries[0])
        {
            if (item.YValue == 0)
                item.Label = " ";
        }

Note, that the label is set to a string containing a white space as the default value of string.Empty is the default one and RadChart puts the calculated label according to the default label format
