Business Object with a generic class

Hi,

For my business Object I use a class which implements this interface:

public interface IGraphPoint<T1,T2>

{

string SerieName { get; }

T1 XValue {

get; }T2 YValue { get ; }

}

So I created a class Point which implements IGraphPoint :

public

class Point : IGraphPoint<double, double>

{ /* Implementation */ }

and I initialise my chart using listDataProvider and CrossTabDataProvider:

ListProvider l = new ListProvider(pointsList); // pointsList = List<Point>

CrosstabDataProvider c = new CrosstabDataProvider();c.RowHeadingSettings = RowHeadingSettings.Auto;

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 = c;

 And my issue is when I set the RowHeadingSettings property of my crossTabDataProvider to "Auto", labels on the X-Axis are well displayed but not in ascending order and when I set the same property to "XValues" I don't have all X-Axis labels and sometimes the x-Axis label displayed is not the corresponding X value of the chart (Maybe I'm not very clear...).(see file attached)

Can you help me?

Thank you

The CrossTab provider will NOT sort the objects. You need to sort your collection (using any order you like) beefore giving it to de CrossTab as a DataSource.

You do not want to use the X-Axis labels as X-Values as this is only usefull for X/Y charts and when Dates are used in the X-axis.
