Hi,

It is not exactly that, what I want to do is to have a grid/color zone below your green curve.

Thanks

Hi ,

Yest that is exactly it !

I have a second problem, this is my scenario :

                 ChartArea area = new ChartArea();
                    this.ChartAlphaRealized.CompositeChart.ChartAreas.Add(area);

                    ChartLayerAppearance myColumnLayer2 = new ChartLayerAppearance();
                    myColumnLayer2.ChartType = ChartType.AreaChart;
                    myColumnLayer2.ChartArea = area;

                    ChartLayerAppearance myColumnLayerAlpha = new ChartLayerAppearance();
                    myColumnLayerAlpha.ChartType = ChartType.ScatterChart;
                    myColumnLayerAlpha.ChartArea = area;

                    //Other possible approach for DataBinding
                    NumericSeries series2 = new NumericSeries();
                    series2.Label = "Lab2";
                    series2.Data.LabelColumn = "Date";
                    series2.Data.ValueColumn = "Volume_rate";
                    series2.Data.DataSource = VolumeNumeric;
                    series2.DataBind();
                    series2.PEs.Add(new PaintElement(Color.Blue));
                    myColumnLayer2.Series.Add(series2);
                    ChartAlphaRealized.CompositeChart.Series.Add(series2);

                    AxisItem axis1 = new AxisItem();
                    axis1.Extent = 20;
                    axis1.DataType = AxisDataType.Numeric;
                    axis1.Labels.ItemFormatString = "<DATA_VALUE:##.##>";
                    axis1.OrientationType = AxisNumber.Y_Axis;
                    axis1.SetLabelAxisType = SetLabelAxisType.DateData;


                    //By defaut the AxisRangeType = Automatic
                    //You are able to set the axis menually with the code:
                    axis1.RangeType = AxisRangeType.Custom;
                    axis1.RangeMin = MinAlphaCumulValue;
                    axis1.RangeMax = MAxAlphaCumulValue;
                    axis1.MajorGridLines.Visible = false;
                    area.Axes.Add(axis1);


                    AxisItem axisX = new AxisItem();
                    axisX.DataType = AxisDataType.String;
                    axisX.Labels.ItemFormatString = "<ITEM_LABEL>";
                    axisX.OrientationType = AxisNumber.X_Axis;
                    axisX.SetLabelAxisType = SetLabelAxisType.ContinuousData;
                    axisX.MajorGridLines.Visible = false;
                    area.Axes.Add(axisX);
                   // axisX.ScrollScale.Visible = true;

                    myColumnLayer2.AxisX = axisX;
                    myColumnLayer2.AxisY = axis1;
                    this.ChartAlphaRealized.CompositeChart.ChartLayers.Add(myColumnLayer2);

                    //for alpha
                    NumericSeries series1 = new NumericSeries();
                    series1.DataBind(AlphaTable, "Alpha_partial", "Date");
                    series1.PEs.Add(new PaintElement(Color.Red));
                    myColumnLayerAlpha.Series.Add(series1);
                    ChartAlphaRealized.CompositeChart.Series.Add(series1);

                    myColumnLayerAlpha.AxisX = axisX;
                    myColumnLayerAlpha.AxisY = axis1;

                    this.ChartAlphaRealized.CompositeChart.ChartLayers.Add(myColumnLayerAlpha);
                    ScatterChartAppearance sca1 = new ScatterChartAppearance();
                    sca1.ConnectWithLines = true;
                    sca1.Icon = SymbolIcon.Circle;
                    sca1.IconSize = SymbolIconSize.Large;
                    myColumnLayerAlpha.ChartTypeAppearance = sca1;

However, the scatterline does not appair, do you know why ?

Thanks

That works thanks a lot !

Maybe I didn`t understand your scenario, but if you want to achieve desired behavior (from the screenshot in the previous post) you should used LineAreaChart instead of ScatterChart (with property ConnectWithLines = true). Please take a look at the attached sample in my previous post for more details and let me know if you have any questions.
