Stacked Bar in Blazor Charts Component
13 Sep 202424 minutes to read
Stacked Bar
Stacked Bar Chart is a chart with Y values stacked over one another in the series order. It shows the relation between individual values to the total sum of the points. To render a stacked bar series in your chart, define the series Type as StackingBar in your chart configuration. This indicates that the data should be represented as a stacked bar chart, where each bar consists of multiple segments stacked horizontally on top of each other.

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 Stacked Bar series.
Fill
The Fill property determines the color applied to the series.

new StackedData { X = "2018", Y = 175.4, Y1 = 166.7, Y2 = 112.9, Y3 = 61.9 },
new StackedData { X = "2019", Y = 189.0, Y1 = 182.9, Y2 = 122.4, Y3 = 71.5 },
new StackedData { X = "2020", Y = 202.7, Y1 = 197.3, Y2 = 120.9, Y3 = 82.0 }
};
}The Fill property can be used to apply a gradient color to the stacked bar 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.
