DataFormula Property (SpreadChart)

Gets or sets the data formula. This action will re-build the chart's series.

Syntax

Visual Basic
C#

'Declaration
 
Public Property DataFormula As System.String

'Usage
 
Dim instance As SpreadChart
Dim value As System.String
 
instance.DataFormula = value
 
value = instance.DataFormula

public System.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.
