How to provide Pivot Chart module's functionality using the Pivot Grid module

Hello Julien,
Here is an example of how to implement this functionality:

C#
[NavigationItem("B191875")]  
public class MyAnalisys : NamedBaseObject {  
    public MyAnalisys(Session session)  
        : base(session) {  
    }  

    [ValueConverter(typeof(TypeToStringConverter))]  
    public Type TargetObjectType {  
        get { return GetPropertyValue<Type>("TargetObjectType"); }  
        set { SetPropertyValue<Type>("TargetObjectType", value); }  
    }  
    [CriteriaObjectTypeMember("TargetObjectType")]  
    [Size(SizeAttribute.Unlimited)]  
    [Custom("RowCount", "0")]  
    [EditorAlias(EditorAliases.ExtendedCriteriaPropertyEditor)]  
    public string Criteria {  
        get { return GetPropertyValue<string>("Criteria"); }  
        set { SetPropertyValue<string>("Criteria", value); }  
    }  
    [ElementTypeProperty("TargetObjectType")]  
    [EditorAlias(EditorAliases.ListPropertyEditor)]  
    public IList Objects {  
        get {  
            IObjectSpace os = ObjectSpace.FindObjectSpaceByObject(this);  
            CollectionSource collectionSource = new CollectionSource(os, TargetObjectType, false, CollectionSourceMode.Proxy);  
            collectionSource.Criteria.Add("Analisys", CriteriaOperator.Parse(Criteria));  
            return (IList)collectionSource.Collection;  
        }  
    }  
}  
public class MyAnalisysController : ViewController<DetailView> {  
    internal ListPropertyEditor ObjectsPreviewEditor {  
        get { return View.FindItem("Objects") as ListPropertyEditor; }  
    }  
    private bool IsValidAnalisys(MyAnalisys analisys) {  
        return analisys != null && analisys.TargetObjectType != null;  
    }  
    private void ObjectSpace_ObjectChanged(object sender, ObjectChangedEventArgs e) {  
        if(object.Equals(View.CurrentObject, e.Object) && e.PropertyName == "TargetObjectType") {  
            ListPropertyEditor objectsPreview = ObjectsPreviewEditor;  
            if(objectsPreview != null && IsValidAnalisys(View.CurrentObject as MyAnalisys)) {  
                if(objectsPreview.Frame != null) {  
                    objectsPreview.BreakLinksToControl(true);  
                    objectsPreview.Frame.SetView(null);  
                }  
                objectsPreview.Model.View = GetAnalisysListViewModel(View.CurrentObject as MyAnalisys);  
                objectsPreview.CreateControl();  
            }  
        }  
    }  
    protected override void OnActivated() {  
        base.OnActivated();  
        ListPropertyEditor objectsPreview = ObjectsPreviewEditor;  
        if(objectsPreview != null && IsValidAnalisys(View.CurrentObject as MyAnalisys)) {  
            objectsPreview.Model.View = GetAnalisysListViewModel(View.CurrentObject as MyAnalisys);  
        }  
        View.ObjectSpace.ObjectChanged += new EventHandler<ObjectChangedEventArgs>(ObjectSpace_ObjectChanged);  
    }  

    private string GetAnalysisListViewId(MyAnalisys analisys) {  
        string defaultLisyViewId = Application.FindListViewId(analisys.TargetObjectType);  
        return defaultLisyViewId + "_MyAnalisys";  
    }  
    private IModelView GetAnalisysListViewModel(MyAnalisys myAnalisys) {  
        string viewId = GetAnalysisListViewId(myAnalisys);  
        IModelListView modelListView = Application.FindModelView(viewId) as IModelListView;  
        if(modelListView == null) {  
            modelListView = Application.Model.Views.AddNode<IModelListView>(viewId);  
            modelListView.ModelClass = Application.Model.BOModel.GetClass(myAnalisys.TargetObjectType);  
            modelListView.EditorType = typeof(PivotGridListEditor);  
            new DevExpress.ExpressApp.Model.NodeGenerators.ModelListViewColumnsNodesGenerator().GenerateNodes((ModelNode)modelListView.Columns);  
        }  
        return modelListView;  
    }  
    protected override void OnDeactivated() {  
        View.ObjectSpace.ObjectChanged -= new EventHandler<ObjectChangedEventArgs>(ObjectSpace_ObjectChanged);  
        base.OnDeactivated();  
    }  
    public MyAnalisysController() {  
        TargetObjectType = typeof(MyAnalisys);  
    }  
}  
public class TypeToStringConverter : ValueConverter {  
    public override object ConvertFromStorageType(object stringObjectType) {  
        ITypeInfo info = XafTypesInfo.Instance.FindTypeInfo(stringObjectType as string);  
        if(info == null) return null;  
        return info.Type;  
    }  
    public override object ConvertToStorageType(object objectType) {  
        if(objectType == null) {  
            return null;  
        }  
        return ((Type)objectType).FullName;  
    }  
    public override Type StorageType {  
        get { return typeof(string); }  
    }  
}  

Please test it, and let me know whether the results meet your requirements.
Thanks,
Anatol
