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?
