Forced series problem.

[jfox3721]

I have added a chart to my winform in VB.NET 2008 using the wizard and I selected the 'MultiSeries' option because I plan on dynamically adding different number of series depending on user input.  In design mode the chart, by default, has three series present.   When I go into the 'Series' property and delete any of the series and click 'OK' it will automatically go back to having three.   This same behavior is effecting my code when dynamically adding new series.  How do I prevent this 'forced series' problem from happening?

The number of series is determined by the data:

chart,Opendata(COD.Values,numberOfSeries,numberOfPoints);

Or if you are databinding your chart, the umber of series is inferred from the datasource.

 So do I need to call the chart.opendata command before configuring my series?

 As of now, I do the following

 

Chart1.Series.Clear

For i as integer = 0 to numberOfSeries-1

Dim newSeries as new SeriesAttributes

...configure series

  Chart1.Series.add

Next

Chart1.OpenData(COD.Values, numberOfSeries,numberOfPoints)

  ...add data for each series

Chart1.CloseData(COD.Values)

You can simply  open the COD values and the series should be created automatically. Atleast thats what happens in 6.2
