Since the ColorModel will use the same color for columns and some lines, I recommend this approach... handle the ChartDrawItem event:

void UltraChart1_ChartDrawItem(object sender, ChartDrawItemEventArgs e)

{

Box b = e.Primitive as Box;

if (b != null && b.Layer is ColumnLayer)

{

b.PE = new PaintElement(Color.Yellow);

}

}

David,

Thanks for the help that was exactly what I needed.  It is all so easy once you know how :) One last question.  I am using these 3 colors for the line portion of the chart (see below), how can i have the column chart use a 4th color?  Currently when it binds the column chart data it uses Color.SteelBlue for the color as expected but how can I change that to something else? 

Color[] chartColors = new Color[] { Color.SteelBlue, Color.LimeGreen, Color.Red };
ultraChart1.ColorModel.ModelStyle = ColorModels.CustomLinear;
ultraChart1.ColorModel.CustomPalette = chartColors;

 1) How can I use the line data as the legend?

            this.ultraChart1.Legend.Visible = true;
            this.ultraChart1.Legend.DataAssociation = ChartTypeData.LineData;

2) I need the scale and the range of the column chart data to be based on dtColChart data, right now it is stuck at 100 even though one of the data points in there is 255.

i didn't experience that when i ran this code.  the y-axis goes up to 255.  please make sure Axis.Y.RangeType is set to Auto.

3) How can I adjust the thickness of the column data plots?

            this.ultraChart1.ColumnLineChart.Column.ColumnSpacing = 1;

either that, or set some margins on the x-axis using the properties under Axis.X.Margins.

i am attaching a picture of what i see when i add a new chart to a form, set the ChartType to ColumnLineChart, and paste your code into Form1_Load, along with my changes suggested above.

Argh..actually only partially

Using the data below gets me the look I want but I have 3 questions

 1) How can I use the line data as the legend?

2) I need the scale and the range of the column chart data to be based on dtColChart data, right now it is stuck at 100 even though one of the data points in there is 255.

3) How can I adjust the thickness of the column data plots?
