Hello Raj,
You can use the built-in filtering functionality to achieve the desired effect (note that you will need to introduce one additional read-only property of type
System.DayOfWeek that will be used by the filtering mechanism):
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
var rand = new Random(123456);
List<ChartData> data = new List<ChartData>();
for (int i = 0; i < 21; i++)
{
data.Add(new ChartData() { Date = DateTime.Today.AddDays(i), Value = rand.Next(10, 100) });
}
SeriesMapping sm = new SeriesMapping();
sm.SeriesDefinition = new BarSeriesDefinition();
sm.ItemMappings.Add(new ItemMapping("Date", DataPointMember.XCategory));
sm.ItemMappings.Add(new ItemMapping("Value", DataPointMember.YValue));
sm.FilterDescriptors.Add(new ChartFilterDescriptor("FormattedDate", typeof(DayOfWeek), FilterOperator.IsNotEqualTo, DayOfWeek.Saturday));
sm.FilterDescriptors.Add(new ChartFilterDescriptor("FormattedDate", typeof(DayOfWeek), FilterOperator.IsNotEqualTo, DayOfWeek.Sunday));
RadChart1.DefaultView.ChartArea.AxisX.DefaultLabelFormat = "ddd";
RadChart1.SeriesMappings.Add(sm);
RadChart1.ItemsSource = data;
}
}
public class ChartData
{
public DateTime Date
{
get;
set;
}
public DayOfWeek FormattedDate
{
get
{
return this.Date.DayOfWeek;
}
}
public double Value
{
get;
set;
}
}
Hope this helps.
All the best,
