how to put chart directly on map

MaxenceIRITIE

hi,

i have done my project using silverlight and it possible to display some charts depending to application context. I need to put these chart on the map to become more expressive for users. But i don't know how to make it. In the help, i saw it's possible to display chart on popup and it's not what i need. I need to draw more than twenty chart directly in georeferenced location.

thank you for my problem addressed.
I found a simple solution to be implemented by relying on the indication of 'Droux' and this downloadable sample.


1 - Import Project ESRI.ArcGIS.Samples.PieChartSymbology or its DLL. (downloadable on the link given)
2 - use the imported project.

In my case, I wrote a method to define a graphic containing a symbol modeled on the pie chart as shown below

        Graphic proc_get_pieSymbol(double gps_x, double gps_y, KeyValuePair<string, int>[] _serie)         {              // PIE Symbol definition             PieMarkerSymbol _symbol = new ESRI.ArcGIS.Samples.PieChartSymbology.PieMarkerSymbol();              // Graphic definition             Graphic _graphic = new Graphic();              // Independant value definition             foreach (var elt in _serie)             {                 _symbol.Fields.Add(new ESRI.ArcGIS.Samples.PieChartSymbology.Field() { DisplayName = elt.Key, FieldName = elt.Key });             }              // Attach the preview symbol to a graphic for graphic layer             _graphic.Symbol = _symbol;              // Definition of dependant value. Note KeyValuePair<string, objet> is necessary to define value. The key must be an sepecific "independant value" and "object" is the dependant.             // In my case, object is <int>             foreach (var elt in _serie)             {                 _graphic.Attributes.Add(new KeyValuePair<string, object>(elt.Key, elt.Value));             }              // definition of destination gps position on the map             _graphic.Geometry = new MapPoint(gps_x, gps_y);               // the pie Symbol as Graphic for Graphics Layer is right now!              return _graphic;         }

I hope this post will help other developers!
