Formula Code Types

For Formula code types, the CodeText property of a function class must contain code that calculates the value of a function using a parameter. The code should fit into a single line and represents the right hand side of an equation.

To write code in Visual Basic

Dim yf As C1.Win.C1Chart.YFunction = New C1.Win.C1Chart.YFunction()        
yf.CodeType = C1.Win.C1Chart.FunctionCodeTypeEnum.Formula        
yf.CodeLanguage = C1.Win.C1Chart.FunctionCodeLanguageEnum.VB        
yf.CodeText = "x*x"        
yf.MinX = -5        
yf.MaxX = 5        
yf.LineStyle.Color = Color.Red        
yf.LineStyle.Thickness = 3           
C1Chart1.ChartGroups(0).ChartData.FunctionsList.Add(yf)

To write code in C#

C1.Win.C1Chart.YFunction yf = new C1.Win.C1Chart.YFunction();                 
yf.CodeType = C1.Win.C1Chart.FunctionCodeTypeEnum.Formula;        
yf.CodeText = "x*x";                
yf.MinX = -5;        
yf.MaxX = 5;        
yf.LineStyle.Color = Color.Red;        
yf.LineStyle.Thickness = 3;                 
c1Chart1.ChartGroups[0].ChartData.FunctionsList.Add(yf);
