public bool CalculateBarWidthReduction { get; set; }
true to calculate the bar width reduction value. Otherwise, false. The default value is false.
When the value of CalculateBarWidthReduction is set to true, the value of the bar width reduction will be calculated and stored in BarWidthReduction. Otherwise, the value stored in BarWidthReduction will be set to zero.
