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.

· 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)

· 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);

· Delphi

var

yf: C1.Win.C1Chart.YFunction;

begin

yf := C1.Win.C1Chart.YFunction.Create;

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);

end;
