SplineSeriesDefinition

[Marciano]

I'm trying make one chart with many series to compare, for example estimated vs effectived cash flow, I tried for several ways but until now I could not.

If possible I need one example that use aggregation function (sum) and show many series with date in x axys.

Below is more or less what I want.

List<List<SplineChartAux>> itemsSource = new List<List<SplineChartAux>>();
                Random r = new Random();

                int index = 0;
                if (MyDataGrid.GroupDescriptors.OfType<ColumnGroupDescriptor>().Count() > 0)
                {
                    var column = MyDataGrid.GroupDescriptors.OfType<ColumnGroupDescriptor>().First();
                
                    var ds = new List<String>();

                    var list = (this.DataSource as IEnumerable);
                    foreach (var item in list)
                    {
                        ds.Add(item.GetType().GetProperty(column.Column.UniqueName).GetValue(item, null) as string);
                    }

                    ds = ds.Distinct().ToList();

                    RadChart1.SeriesMappings.Clear();

                    foreach (var item in ds)
                    {
                        SeriesMapping sm = new SeriesMapping();
                        sm.SeriesDefinition = new SplineSeriesDefinition();
                        sm.LegendLabel = item;
                        sm.CollectionIndex = index;

                        sm.ItemMappings.Add(new ItemMapping("XValue", DataPointMember.XCategory));
                        sm.ItemMappings.Add(new ItemMapping("YValue", DataPointMember.YValue, aggFunct));

                        RadChart1.SeriesMappings.Add(sm);

                        index++;
                    }
                   
                }


                RadChart1.ItemsSource = itemsSource;

Hi Marciano,

Take a look at our demo with full source code that demonstrates AggregateFunction (Sum) in action and the XAxis values are of type DateTime. For more information about Aggregation you can review our help topic - http://www.telerik.com/help/silverlight/radchart-features-grouping-and-aggregation.html.
