    Syntax
    'Declaration
     
    Public Property DataFormula As String
    'Usage
     
    Dim instance As SpreadChart
    Dim value As String
     
    instance.DataFormula = value
     
    value = instance.DataFormula
    public string DataFormula {get; set;}

    Property Value

    The data formula.
    Remarks
    This property is not designed for persisting so you should save and re-use the value and access infrequently.
    Example
    This example creates a chart control.
