I need to create a chart with areas (100%) clickable.
So I used StackedMountainRenderableSeries series.

the problem is that the graph remains flat (all lines are 0).

            <s:SciChartSurface x:Name="ChartTgt"  Grid.Column="0" s:ThemeManager.Theme="Chrome" >
                <s:NumericAxis  x:Name="AxeXTgt"/>
                <s:NumericAxis x:Name="AxeYTgt"/>

        AxeXTgt.LabelProvider = new CustomLabelProvider(months.ToArray());
                AxeYTgt.TextFormatting = "#0'%'";
            foreach (var cat in categ)
                XyDataSeries<double, double> serie = new XyDataSeries<double, double>();
                foreach (var m in months)
                    serie.Append(months.IndexOf(m), tgt.FirstOrDefault(o => o.CAT == cat && o.PERIOD == m)?.QTY ?? 0);
                ChartTgt.RenderableSeries.Add(new StackedMountainRenderableSeries { AntiAliasing = true, DataSeries = serie, SeriesColor = colors[categ.IndexOf(cat)], AreaBrush = new SolidColorBrush(colors[categ.IndexOf(cat)]), IsOneHundredPercent = true});

but if I put IsOneHundredPercent false, I can see the lines.

the version of the DLL is
