Example 


Gets or sets the data formula. This action will re-build the chart's series.
Syntax
'Declaration
 
Public Overridable Property DataFormula As String
'Usage
 
Dim instance As SpreadChart
Dim value As String
 
instance.DataFormula = value
 
value = instance.DataFormula
public virtual 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 sets the DataFormula property.
