HI

I am showing BarSeries using the following x-y pairs:
(1.45, 12)
(1.46, 13)
(2.45, 16)
(12.45, 23)
(178.45, 332)
...

The problem is how to compute the proper BarWidth avoid bars overlapping. My algorithm is like this:
Step 1: Find the closest bars on x-axis.((1.45, 12) and (1.46, 13) are closest bars and the difference is only 0.01)
Step 2: Convert this samllest difference 0.01 to parent relative value. Since the default bar width is 2 with unit of NRelativeUnit.ParentPercentage
Step 3: Choose the min value from the converted value and the default value 2

But i don't know how to do the conversion in step2 above, i've tried the code below but doesn't work, any help?

gap = xValues[minGapIndex + 1] - xValues[minGapIndex];

var xAxisLength = (_chartWrapper.Chart.Axes[(int)StandardAxis.PrimaryX] as NAxis).Scale.RulerRange.GetLength();

gap = gap / xAxisLength * 100;

barSeries.BarWidth = new NLength((float)Math.Min(gap,2), NRelativeUnit.ParentPercentage);
