business object

hello,

I want to bind a chart with my business object.

I have a class:

class

MyData

{

string _serieName;

object _xValue; double _yValue;public MyData(string serieName, object xvalue, double value)

{

_serieName = serieName; 

_xValue = xvalue;

 

_yValue = value;

}

public object XValue {get { return _xValue; } }

public string SerieName { get { return _serieName; } }public double YValue {get { return _yValue; } }

}

 xvalue is an object because I can have double values, datetime values or string values. I can have a chart but I want the axisX to be sorted in ascending order because when I try like that:

MyData[] testArray = new MyData[3];

testArray[0] =

new MyData"serieA", 2, 12);testArray[1] = new MyData("SerieB", 1, 16);

testArray[2] =

new MyData("SerieC", 3, 15);ListProvider l = new ListProvider(testArray);CrosstabDataProvider c = new CrosstabDataProvider();

c.DataSource = l;

chart.DataSourceSettings.Fields.Add(

new FieldMap("SerieName", FieldUsage.ColumnHeading));chart.DataSourceSettings.Fields.Add(new FieldMap("XValue", FieldUsage.RowHeading) );

chart.DataSourceSettings.Fields.Add(

new FieldMap("YValue", FieldUsage.Value));

chart.DataSource = testArray;

I have a good chart but labels on axisX are in this order : 2 - 1 - 3 (the order in the tab).

I think it's a normal behaviour but is there a way to display a chart with axisX sorted?

Thank you.
