Gantt chart name suggestion - Length or Width

Question

I'm not sure if this is the right Stack Exchange site to ask good name for bars in Gantt Chart.

Data Structure

public class GanttChartData
{
    public ICollection<GanttBarData> BarCollection { get; set; }
}

public class GanttBarData
{
    public string Name { get; set; }

    public double Length { get; set; }
}

Question Should I use Length or Width to represent length of a bar? I know it would be horizontal bar always.

Answer 1

As Wikipedia states:

In geometric measurements, length is the longest dimension of an object.

Hence your choice of BarLength is correct as the horizontal length is (almost!) always going to be the longest dimension of a bar in your chart.
