Column Chart in Blazor Charts Component
9 Dec 20228 minutes to read
Column
Column Chart is the most common chart type that is used to compare Frequency, Count, Total, or Average of data in different categories. It is ideal for showing variations in the value of an item over time. To render a column series, set series Type as Column.
@using Syncfusion.Blazor.Charts
<SfChart>
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"/>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="Y" Type="ChartSeriesType.Column">
</ChartSeries>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double Y { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "South Korea", Y= 39.4 },
new ChartData { X= "India", Y= 61.3 },
new ChartData { X= "Pakistan", Y= 20.4 },
new ChartData { X= "Germany", Y= 65.1 },
new ChartData { X= "Australia", Y= 15.8 },
new ChartData { X= "Italy", Y= 29.2 },
new ChartData { X= "United Kingdom", Y= 44.6 },
new ChartData { X= "Saudi Arabia", Y= 9.7 },
new ChartData { X= "Russia", Y= 40.8 },
new ChartData { X= "Mexico", Y= 31 },
new ChartData { X= "Brazil", Y= 75.9 },
new ChartData { X= "China", Y= 51.4 }
};

Column space and width
The ColumnSpacing and ColumnWidth properties are used to customize the space between columns.
@using Syncfusion.Blazor.Charts
<SfChart>
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="Y" Type="ChartSeriesType.Column" ColumnSpacing="0.2" ColumnWidth="0.2" >
</ChartSeries>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double Y { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "South Korea", Y= 39.4 },
new ChartData { X= "India", Y= 61.3 },
new ChartData { X= "Pakistan", Y= 20.4 },
new ChartData { X= "Germany", Y= 65.1 },
new ChartData { X= "Australia", Y= 15.8 },
new ChartData { X= "Italy", Y= 29.2 },
new ChartData { X= "United Kingdom", Y= 44.6 },
new ChartData { X= "Saudi Arabia", Y= 9.7 },
new ChartData { X= "Russia", Y= 40.8 },
new ChartData { X= "Mexico", Y= 31 },
new ChartData { X= "Brazil", Y= 75.9 },
new ChartData { X= "China", Y= 51.4 }
};
}
Grouped column
You can use the GroupName property to group the data points in the column type charts. Data points with same group name are grouped together.
@using Syncfusion.Blazor.Charts
<SfChart>
<ChartPrimaryXAxis ValueType="@Syncfusion.Blazor.Charts.ValueType.Category">
</ChartPrimaryXAxis>
<ChartSeriesCollection>
<ChartSeries DataSource="@ChartPoints" XName="Year" YName="USA_Total" GroupName="USA" ColumnWidth="0.7" ColumnSpacing="0.1" Type="ChartSeriesType.Column">
</ChartSeries>
<ChartSeries DataSource="@ChartPoints" XName="Year" YName="USA_Gold" GroupName="USA" ColumnWidth="0.5" ColumnSpacing="0.1" Type="ChartSeriesType.Column">
</ChartSeries>
<ChartSeries DataSource="@ChartPoints" XName="Year" YName="UK_Total" GroupName="UK" ColumnWidth="0.7" ColumnSpacing="0.1" Type="ChartSeriesType.Column">
</ChartSeries>
<ChartSeries DataSource="@ChartPoints" XName="Year" YName="UK_Gold" GroupName="UK" ColumnWidth="0.5" ColumnSpacing="0.1" Type="ChartSeriesType.Column">
</ChartSeries>
</ChartSeriesCollection>
</SfChart>
@code{
public class ColumnData
{
public string Year { get; set; }
public double USA_Total { get; set; }
public double USA_Gold { get; set; }
public double UK_Total { get; set; }
public double UK_Gold { get; set; }
public double China_Total { get; set; }
public double China_Gold { get; set; }
}
public List<ColumnData> ChartPoints { get; set; } = new List<ColumnData>
{
new ColumnData { Year = "2012", USA_Total = 104, USA_Gold = 46, UK_Total = 65, UK_Gold = 29, China_Total = 91, China_Gold = 38},
new ColumnData { Year = "2016", USA_Total = 121, USA_Gold = 46, UK_Total = 67, UK_Gold = 27, China_Total = 70, China_Gold = 26},
new ColumnData { Year = "2020", USA_Total = 113, USA_Gold = 39, UK_Total = 65, UK_Gold = 22, China_Total = 88, China_Gold = 38},
};
}

{
new ChartData { X= "South Korea", Y= 39.4 },
new ChartData { X= "India", Y= 61.3 },
new ChartData { X= "Pakistan", Y= 20.4 },
