Initially I made a range chart but I could not find out how to change the width of the line to be the size I wanted, however the coloring worked.

Next I tried to instead use a stock chart to do the same thing, and while the width is great, I can't seem to figure out how to change the color of each bar.  I have the following and it doesn't seem to work.

Color lineColor = Color.FromArgb(convertedItems[0],convertedItems[1],convertedItems[2]);
range.FillStyles[i] = new NColorFillStyle(lineColor);

Any suggestions?

Hi Jerry,
The marker style has properties called Width and Height that control the size of the marker - for example:

   NChart chart = nChartControl1.Charts[0];

   NBarSeries bar = new NBarSeries();

   bar.Values.Add(10);
   bar.Values.Add(20);
   bar.Values.Add(30);

   bar.MarkerStyle.Visible = true;
   bar.MarkerStyle.PointShape = PointShape.Diamond;
   bar.MarkerStyle.Width = new NLength(10);
   bar.MarkerStyle.Height = new NLength(20);

   chart.Series.Add(bar);
