100% Stacked Area in Blazor Charts Component
13 Sep 202424 minutes to read
100% Stacked Area Chart
100% Stacked Area Chart displays multiple series of data as stacked areas, ensuring that the cumulative proportion of each stacked element always totals 100%. Hence, the y-axis will always be rendered with the range 0–100%. To render a 100% stacked area series in your chart, define the series Type as StackingArea100 in your chart configuration. This indicates that the data should be represented as a 100% stacked area chart, where the cumulative values for each data point are expressed as a percentage of the total. This ensures that the sum of all series at each point is always 100%.

Binding data with series
You can bind data to the chart using the DataSource property within the series configuration. The DataSource value can be set using either SfDataManager property values or a list of business objects. More information on data binding can be found here. To display the data correctly, map the fields from the data to the chart series’ XName and YName properties.

}Series customization
The following properties can be used to customize the 100% Stacked Area series.
Fill
The Fill property determines the color applied to the series.
@using Syncfusion.Blazor.Charts
<SfChart>
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
<ChartSeriesCollection>
<ChartSeries DataSource="@ChartDataList" XName="X" YName="Y" Fill="red" Type="Syncfusion.Blazor.Charts.ChartSeriesType.StackingArea100" />
<ChartSeries DataSource="@ChartDataList" XName="X" YName="Y1" Fill="blue" Type="Syncfusion.Blazor.Charts.ChartSeriesType.StackingArea100" />
<ChartSeries DataSource="@ChartDataList" XName="X" YName="Y2" Fill="green" Type="Syncfusion.Blazor.Charts.ChartSeriesType.StackingArea100" />
</ChartSeriesCollection>
</SfChart>
@code {
public class ChartData
{
public double X { get; set; }
public double Y { get; set; }
public double Y1 { get; set; }
public double Y2 { get; set; }
}
public List<ChartData> ChartDataList = new List<ChartData>
{
new ChartData{ X=2000, Y= 0.61, Y1= 0.03, Y2= 0.48},
new ChartData{ X=2001, Y= 0.81, Y1= 0.05, Y2= 0.53 },
new ChartData{ X=2002, Y= 0.91, Y1= 0.06, Y2= 0.57 },
new ChartData{ X=2003, Y= 1, Y1= 0.09, Y2= 0.61 },
new ChartData{ X=2004, Y= 1.19, Y1= 0.14, Y2= 0.63 },
new ChartData{ X=2005, Y= 1.47, Y1= 0.20, Y2= 0.64 },
new ChartData{ X=2006, Y= 1.74, Y1= 0.29, Y2= 0.66 },
new ChartData{ X=2007, Y= 1.98, Y1= 0.46, Y2= 0.76 },
new ChartData{ X=2008, Y= 1.99, Y1= 0.64, Y2= 0.77 },
new ChartData{ X=2009, Y= 1.70, Y1= 0.75, Y2= 0.55 }
};
}The Fill property can be used to apply a gradient color to the 100% stacked area series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

}Empty points
Data points with null, double.NaN or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.
Mode
Use the Mode property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap.
