LogBase Property

Gets or sets the logarithmic base for the axis. Default value double.NaN corresponds to the default linear axis.

Syntax

Visual Basic
C#

'Declaration
 
Public Property LogBase As System.Double

'Usage
 
Dim instance As Axis
Dim value As System.Double
 
instance.LogBase = value
 
value = instance.LogBase

public System.double LogBase {get; set;}

Example

This example sets the LogBase property.

gcSpreadSheet1.ActiveSheet.SetArray(0, 0, new object[,] { { 1 }, { 2 }, { 3 }, { 4 }, { 5 }, { 6 }, { 7 }, { 8 }, { 9 }, { 10 } });

//stroke

//font
chart.AxisX.FontSize = 12;
chart.AxisX.FontFamily = FontFamily;
chart.AxisX.FontStyle = FontStyles.Italic;
chart.AxisX.FontWeight = FontWeights.Bold;

chart.AxisX.Reversed = true;
chart.AxisX.LogBase = 100;
chart.AxisX.UseLogBase = true;
