Its back up. So you can check that out if you want. But the exampl linked is really more for if you want to create the series based on a template in Xaml. If you are already creating the series collection in your View Model have you tried just binding it to the chart?

I.E if the property holding the SeriesCollection on your DataContext is called Series. Have you tried

<XamWebChart Series="{Binding Series} ...

Dear Graham,

how can i redo this but for stacked column series, its really urgent.

Thanks

For xamWebChart or for xamDataChart? Could you describe what your data looks like?

its xamDataChart,

 this.grdXmlData.ItemsSource = markets;  //this for the grid and its working great

            CategoryXAxis xAxis = new CategoryXAxis();
            xAxis.ItemsSource = markets;
            xAxis.Label = "{Date}";
            NumericYAxis numYAxis = new NumericYAxis();

           this.DataChart.Axes.Add(xAxis);
          this.DataChart.Axes.Add(numYAxis);

   StackedColumnSeries stackedColumnSeries = new StackedColumnSeries();        
   stackedColumnSeries.XAxis = xAxis;
   stackedColumnSeries.YAxis = numYAxis;
    stackedColumnSeries.ItemsSource = markets;

 for (int nbrand = 0; nbrand < brandcount; nbrand++)
 {

             StackedFragmentSeries stackedFragment = new StackedFragmentSeries();
                // creating the brands' graphs and assigning the values
                stackedFragment.Name = "g" + nbrand;
                stackedFragment.Title = cbrand;
               // stackedFragment.SetBinding(StackedFragmentSeries.ItemsSourceProperty, new Binding("Item.value" + nbrand));
                //stackedFragment.ItemsSource = markets;
                stackedFragment.ValueMemberPath = "value" + nbrand;
                // stackedFragment.LegendItemTemplate = customLegendItemTemplate;
                StackPanel sp = new StackPanel();
                TextBlock tb1 = new TextBlock();
                TextBlock tb2 = new TextBlock();
                sp.Orientation = System.Windows.Controls.Orientation.Vertical;
                sp.Children.Add(tb1);
                sp.Children.Add(tb2);
                tb1.SetBinding(TextBlock.TextProperty, new Binding("Series.Title"));
                tb2.SetBinding(TextBlock.TextProperty, new Binding("Item.value" + nbrand));
                stackedFragment.ToolTip = sp;
                // add the brands' graphs to the chart         
                stackedColumnSeries.Series.Add(stackedFragment);

}

     this.DataChart.Series.Add(stackedColumnSeries);

//here is the class

  Markets markets = new Markets();

 public class Markets : ObservableCollection<Market>
    {
        public Markets()
        {

//data retrieval from xml

 field2 = "value" + i;

  Market.AddProperty(field2, typeof(double)); 

 Market market1 = new Market();

  market1.SetPropertyValue(field2, msval);

  market1.SetPropertyValue("Date",  String.Format("{0:y}", curDate).ToString());
               
 Add(market1);

}

 public class Market : ICustomTypeProvider
    {
      //  public String Date { get; set; }

        CustomTypeHelper<Market> helper = new CustomTypeHelper<Market>();


        public static void AddProperty(String name)
        {
            CustomTypeHelper<Market>.AddProperty(name);
        }

        public static void AddProperty(String name, Type propertyType)
        {
            CustomTypeHelper<Market>.AddProperty(name, propertyType);
        }

        public static void AddProperty(String name, Type propertyType, List<Attribute> attributes)
        {
            CustomTypeHelper<Market>.AddProperty(name, propertyType, attributes);
        }


        public void SetPropertyValue(string propertyName, object value)
        {
            helper.SetPropertyValue(propertyName, value);
        }

        public object GetPropertyValue(string propertyName)
        {
            return helper.GetPropertyValue(propertyName);
        }

        public PropertyInfo[] GetProperties()
        {
            return helper.GetProperties();
        }

        public Type GetCustomType()
        {
            return helper.GetCustomType();
        }
    }

Hi,

We don't have direct support for that interface yet, as its Silverlight 5. The chart doesn't directly use the Silverlight binding system for fetching column values because its too slow for volume scenarios.

I'm uncertain where that interface hooks into Silverlight, not having read into it yet. If it hooks into the binding system, then it wont work for describing a type to the chart yet, but if it hooks in to the reflection subsystem at a lower level, then it has a chance of working.

I'll try to run an experiment, but I can tell you that it will work if you use nominal types instead of dynamic types such as you are currently. You can also generate nominal types on the fly if the columns you are dealing with are completely dynamic. I'll try to find some samples I've done of this before.

Hi Graham,

I am facing the same issue with xamGrid - Silverlight. From the description you gave in the post above, it make sense that ICustomTypeProvider works at silverlight binding level but xamGrid works at a level lower than that.

The workaround you suggested of creating runtime types works fine but causes performance overhead. I would ideally like to see ICustomTypeProvider or DynamicObjects binding seamlessly with Infragistics components.

Is there any plan to support this in upcoming Infragistics releases ? I have tried Infragistics 12.1 as well, but its still not implemented.

thx alot

Is there any  article or blog that binds the pivot grid with the datachart??

am searching but there is only for webchart

I believe you can just set the Brush property on each fragment.

OK, i will now try to work with the pivotgrid and bind it :)

but i want to ask a question first,

can i chose the colors of the stacked fragments, because i don't want the randomely selected colors i get

i want to specify the color of the fragment when adding it, can i??
