Adding alignment options to the Bar is the best practice

Suggestion: Adding alignment options to the Bar is the best practice

Bar should not be centered on the X-axis by default
Let's take a look at the problem first. I hope the Bar has the correct time width for this room

 public class BarPosition : RecipeBase
 {
     public override string Name => "Bar Positioning";
     public override string Description => "The exact position and size of each bar may be customized.";

     [Test]
     public override void Execute()
     {
         DateTime d1 = DateTime.Parse("2025-1-1 12:00:00");
         DateTime d2 = DateTime.Parse("2025-1-1 12:00:15");
         DateTime d3 = DateTime.Parse("2025-1-1 12:00:20");
         DateTime d4 = DateTime.Parse("2025-1-1 12:00:50");
         double p1 = d1.ToOADate();
         double p2 = d2.ToOADate();
         double p3 = d3.ToOADate();
         double p4 = d4.ToOADate();

         double w1 = p2 - p1;
         double w2 = p3 - p2;
         double w3 = p4 - p3;
         double xz = w1 / 2;
         ScottPlot.Bar[] bars =
         {
             new() { Position = p1, Value = 10, ValueBase = 3,Size=w1, FillColor = Colors.Red },
             new() { Position = p2, Value = 5, ValueBase = 0,Size=w2, FillColor = Colors.Blue },
             new() { Position = p3, Value = 3, ValueBase = 2,Size=w3, FillColor = Colors.Green },
         };

         myPlot.Add.Bars(bars);
         myPlot.Axes.DateTimeTicksBottom();
     }
 }

The result is as follows: This is confusing and confusing

I traced the calculation issue here

public class Bar : IHasFill, IHasLine
{
   ......
   public CoordinateRect Rect
   {
       get
       {
           return Orientation == Orientation.Vertical
               ? new CoordinateRect(
                   left: Position - Size / 2,
                   right: Position + Size / 2,
                   bottom: ValueBase,
                   top: Value)
               : new CoordinateRect(
                   left: ValueBase,
                   right: Value,
                   bottom: Position - Size / 2,
                   top: Position + Size / 2);
       }
   }
}

If I change it this way, I can got to what I expected

    public CoordinateRect Rect
    {
        get
        {
            return Orientation == Orientation.Vertical
                ? new CoordinateRect(
                    left: Position  ,
                    right: Position + Size  ,
                    bottom: ValueBase,
                    top: Value)
                : new CoordinateRect(
                    left: ValueBase,
                    right: Value,
                    bottom: Position,
                    top: Position);
        }
    }

That's already wonderful！
Of course, if a percentage value is specified for the fill color ,and Adaptive scaling label, that would be perfect. Thank you

Start with the BarPosition recipe and the Bar.Rect entry point shown in the issue, then trace Add.Bars and the bar rendering tests or examples around them. Compare the current centered placement with the requested alignment options and define completion by reproducing the expected DateTime bar layout. The percentage fill-color and adaptive-scaling requests are additional scope to clarify.
