Hello,

I seem to not be able to display date in the tool tip. Here is a snippet of the code that I have:

 

 

DataSeries ds = new DataSeries();

 

ds.Definition =

 

new SplineSeriesDefinition();

 

 

 

ds.Definition.ShowItemToolTips = true;

 

ds.Definition.ItemToolTipFormat =

 

"Date: #X{D}\r\nValue: #Y{F2}";

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/01/2010")) { YValue = 3.134 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/02/2010")) { YValue = 2.828 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/03/2010")) { YValue = 2.827 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/04/2010")) { YValue = 2.752 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/05/2010")) { YValue = 2.696 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/06/2010")) { YValue = 2.718 });

 

ds.Add(

 

new DataPoint(DateTime.Parse("07/07/2010")) { YValue = 2.976 });

 

TimeSeriesChartArea.DataSeries.Add(ds);


When the chart is generated, I see the following when hovering over a data point

Date:
Value: 3.13

As you can see, the Date is blank, while the value is displaying the correct data. I have tried several other formats (MM, yyyy, dd, etc), and all of them displayed blank.

Please help,
Dinko
