    Using an UnBound Data Source
    In This Topic

    You can use the chart in an unbound state without binding it to the data source. In such case, add double values to the chart control without using a datasource.

    Example

    The following example demonstrates adding unbound data to the control.

    C#
    Copy Code
    BarSeries series = new BarSeries();
    series.Values.Add(2.0);
    series.Values.Add(4.0);
    series.Values.Add(3.0);
    series.Values.Add(5.0);
    
    Visual Basic
    Copy Code
    Dim series As New BarSeries()
    series.Values.Add(2.0)
    series.Values.Add(4.0)
    series.Values.Add(3.0)
    series.Values.Add(5.0)
