That worked!!

Thanks so much David - really appreciate it!!

no, that's not possible.

add this line after setting lineLayer.ChartType and it should work:

((LineChartAppearance)lineLayer.ChartTypeAppearance).LineAppearances.Add(lineApp1);

Hey David,

here is the code i used - is it possible just to add the LineAppearance in the NumericSeries?

NumericSeries seriesLine = new NumericSeries();
seriesLine.Data.DataSource = mybudget.GetBudgetLineData(14, 4);
seriesLine.Data.LabelColumn = "Fiscal_Month";
seriesLine.Data.ValueColumn = "Budget";
seriesLine.PEs.Add(new PaintElement(Color.Red));
BudgetChart.CompositeChart.Series.Add(seriesLine);

LineAppearance lineApp1 = new LineAppearance();
lineApp1.LineStyle.EndStyle = LineCapStyle.Square;
lineApp1.Thickness = 10;
lineApp1.IconAppearance.IconSize = SymbolIconSize.Large;
this.BudgetChart.LineChart.LineAppearances.Add(lineApp1);

ChartLayerAppearance lineLayer = new ChartLayerAppearance();
lineLayer.AxisX = xAxisLine;
lineLayer.AxisY = yAxis;
lineLayer.ChartArea = area;
lineLayer.ChartType = ChartType.LineChart;
lineLayer.Series.Add(seriesLine);

Hey David,

LineChartAppearance lineApp = lineLayer.ChartTypeAppearance as LineChartAppearance;

Sorry, but i am just now getting the sytax to add the IconAppearance after the first line

BudgetChart.CompositeChart.ChartLayers[1]

will throw an index out of range exception because you haven't added columnLayer and lineLayer to the chartlayers collection yet.

you can replace the above expression with "lineLayer"

LineChartAppearance lineApp = lineLayer.ChartTypeAppearance as LineChartAppearance;
