Hi,

i have a datachart that has the same datasource as the pivotgrid and using an olap axis. 

<ig:XamDataChart Grid.Row="1" Grid.Column="0"
            x:Name="xmOlapDataChart"  
            VerticalZoombarVisibility="Visible" 
            VerticalZoomable="True"
            HorizontalZoombarVisibility="Visible"
            HorizontalZoomable="True">
            <ig:XamDataChart.Axes>
                <ig:OlapXAxis 
                    x:Name="olapXAxis"
                   DataSource="{StaticResource DataSource}" 
                   SeriesInitialing="olapXAxis_SeriesInitialing" SeriesCreating="olapXAxis_SeriesCreating"
                    OlapAxisSource="Columns"
                    AutoGenerateSeries="True"  
                    Label="{}{Date}"
                    YAxis="{Binding ElementName=xmYAxis1}"/>
                <ig:NumericYAxis x:Name="xmYAxis1" MinimumValue="0" />
            </ig:XamDataChart.Axes>
        </ig:XamDataChart>

the functions for creating the stacked series is below:

 private void olapXAxis_SeriesCreating(object sender, SeriesCreatingEventArgs e)
        {
            e.UserCreate = true;
            // creating the stacked fragments
            StackedFragmentSeries stackedFragment = new StackedFragmentSeries();
            stackedFragment.ValueMemberPath = e.SeriesInfo.Title;

             // adding stacked fragment to the stacked column series

            series.Series.Add(stackedFragment);
            // adding the stacked column series to the data chart
            e.Series = series;
        }

        private void olapXAxis_SeriesInitialing(object sender, SeriesInitialingEventArgs e)
        {
            series = new StackedColumnSeries();
        }

i have also added an XamZoombar to my chart:

<ig:XamZoombar x:Name="xmZoombar" Height="30" Grid.Column="0" Grid.Row="1"  Margin="30,-6,13,5" Style="{StaticResource XamZoombarStyle1}" Background="Transparent" SmallChange="0.0119" >
            <ig:XamZoombar.HorizontalPreviewContent>
                <ig:XamDataChart x:Name="DataChartpreview"    
                                 HorizontalZoombarVisibility="Collapsed"
                                 HorizontalZoomable="True"
                                 VerticalZoomable="False"
                                 VerticalZoombarVisibility="Collapsed" 
                                 IsHitTestVisible="False"
                                 IsTabStop="False" PlotAreaBorderBrush="#efefef" PlotAreaBackground="#efefef"  WindowResponse="Immediate" Background="{x:Null}" GridMode="None" Margin="0" Padding="0">

                    <ig:XamDataChart.Axes>
                        <ig:NumericYAxis x:Name="yAxispreview"  Interval="1" MinimumValue="0" MaximumValue="100">
                            <ig:NumericYAxis.LabelSettings>
                                <ig:AxisLabelSettings Visibility="Collapsed"  />
                            </ig:NumericYAxis.LabelSettings>
                        </ig:NumericYAxis>
                        <ig:OlapXAxis x:Name="xAxispreview" YAxis="{Binding ElementName=yAxispreview}">
                            <ig:OlapXAxis.LabelSettings>
                                <ig:AxisLabelSettings Visibility="Collapsed"/>
                            </ig:OlapXAxis.LabelSettings>
                        </ig:OlapXAxis>
                    </ig:XamDataChart.Axes>
                </ig:XamDataChart>
            </ig:XamZoombar.HorizontalPreviewContent>
        </ig:XamZoombar>

i want the xamzoombar to have a spline series chart in it representing the data of the datachart. how is that possible?

Thanks,

Nazha
