expression.LogBase
expression Required. An expression that returns a ChScaling object.
Example
This example causes the specified axis to use a base 2 logarithmic scale.
Sub SetScaling()
Dim chConstants
Dim scValueAxisScaling
Set chConstants = ChartSpace1.Constants
' Set a variable to the scaling object of the value axis.
Set scValueAxisScaling = ChartSpace1.Charts(0).Axes(chConstants.chAxisPositionValue).Scaling
' Set the scaling type.
scValueAxisScaling.Type = chConstants.chScaleTypeLogarithmic
' Set the base value.
scValueAxisScaling.LogBase = 2
End Sub
