Description
The LogarithmicBase property determines the "degree" or "base" to use to display axis labels when the Axis TChartAxis.Logarithmic property is True.
It does not apply when Axis Logarithmic property is False.
By default is 10 ( log10 )
As an example, try to set it to 2 (binary log) :
Chart1.Axes.Left.Logarithmic := True ;
Chart1.Axes.Left.LogarithmicBase := 2;
It can also be set to floating point numbers, like base "e" :
Chart1.Axes.Left.Logarithmic := True ;
Chart1.Axes.Left.LogarithmicBase := 2.71828182845905;
