Thanks that works good but i have one more problem. Sometimes I have 3 items in my pie chart, 2 items are rendered properly but the third one is below 1 % and instead of showing its name, it shows others, that is nonsense because there is only 1 item that is just renamed others.

Thanks, It works perfect.

When using composite charts, setting most properties directly on the chart control will have no effect.
You have to set the properties on the chart layer, instead.

Dim appearance as New PieChartAppearance()
appearance.OthersCategoryText = "MyText"
appearance.OthersCategoryPercent  = 0
layer.ChartTypeAppearance = appearance

I used one of your sample code, make some testing with the property "OthersCategoryPercent" and set it to zero.  Also, I used the property "OthersCategoryText" and set it to "Testing" but on the graph, I still see the "Other" shows for the legend.

My graph still showing "Other" within the legend and I don't know how to fix it.  Would you give me some suggestions?  Thanks

        UltraChart1.CompositeChart.ChartAreas.Add(area)

        legend.ChartLayers.Add(layer)

        UltraChart1.CompositeChart.Legends.Add(legend)

There's a property called OthersCategoryPercent under PieChart, that is set to 3 by default. This means anything below 3% is grouped into Others, regardless of how many items fall into that category. You can change it to 0 to display everything without having "Others".
