Stacked Bar in Blazor Charts Component
4 Jul 202524 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 = "2015", Y = 127.3, Y1 = 99.5, Y2 = 79.3, Y3 = 38.2 },
new StackedData { X = "2016", Y = 143.4, Y1 = 121.7, Y2 = 91.3, Y3 = 44.0 },
new StackedData { X = "2017", Y = 159.9, Y1 = 142.5, Y2 = 102.4, Y3 = 51.6 },
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.

}Opacity
The Opacity property specifies the transparency level of the Fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

}Corner radius
The ChartCornerRadius property is used to customize the corner radius for Stacked Bar series. This allows you to create bars with rounded corners, giving your chart a more polished appearance. You can customize each corner of the bars using the BottomLeft, BottomRight, TopLeft, TopRight properties.

Stacking group
The StackingGroup property is used to group stacked bar and 100% stacked bar. Bars with same group name are stacked on top of each other.

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.

}Stack labels
The stack labels display cumulative total values for stack segments directly using data labels. If all the values in a stack segment are negative, the stack label is displayed below the point.
The Visible property of the ChartStackLabelSettings is used to enable stack labels. Setting it to true will display the stack labels.

}Customization
The stack labels can be customized using the ChartStackLabelSettings properties as given below.
- Fill - Specifies the background color of the stack labels when border is set. The default value is transparent.
-
Format - Specifies the format of the stack labels. It supports a placeholder
{value}which will be replaced by the stack label value. - Rx - Specifies the rounded corner radius along the X-axis (horizontal direction) for the stack label background. The default value is 5.
- Ry - Specifies the rounded corner radius along the Y-axis (vertical direction) for the stack label background. The default value is 5.
- Angle - Specifies the rotation angle for stack labels in degrees. The default value is 0.
We can customize the font of the stack labels using the ChartStackLabelFont properties as given below:
- TextAlignment - Customizes the alignment of the text within the stack label.
- FontFamily - Customizes the font family for the stack label text.
- Size - Customizes the font size of the stack label text.
- FontStyle - Customizes the font style of the stack label text.
- FontWeight - Customizes the font weight of the stack label text.
- Color - Customizes the color of the stack label text.
We can customize the border of the stack labels using the ChartStackLabelBorder properties as given below:
- Width - Specifies the width of the border around the stack label.
- Color - Specifies the color of the border around the stack label.
To customize the margin, we can use the ChartStackLabelMargin properties as given below:
- Bottom - Specifies the bottom margin of the stack label.
- Top - Specifies the top margin of the stack label.
- Right - Specifies the right margin of the stack label.
- Left - Specifies the left margin of the stack label.
