Axis crossing
An axis can be positioned in the chart area using CrossesAt and CrossesInAxis properties. The CrossesAt property specifies the values (numeric, datetime or logarithmic) at which the axis line has to be intersected with the vertical axis or vice-versa, and the CrossesInAxis property specifies the axis name with which the axis line has to be crossed.
@using Syncfusion.Blazor.Charts
<SfChart Title="Olympic Medals">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" CrossesAt="15"/>
<ChartPrimaryYAxis CrossesAt="5"/>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue" Type="ChartSeriesType.Column"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double YValue { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "USA", YValue= 46 },
new ChartData { X= "GBR", YValue= 27 },
new ChartData { X= "CHN", YValue= 26 },
new ChartData { X= "UK", YValue= 26 },
new ChartData { X= "AUS", YValue= 26 },
new ChartData { X= "IND", YValue= 26 },
new ChartData { X= "DEN", YValue= 26 },
new ChartData { X= "MEX", YValue= 26 },
};
}
Title
A title can be added to the axis using Title property to provide quick information to the user about the data plotted in the axis. The title text can be customized using ChartAxisTitleStyle of the axis.
@using Syncfusion.Blazor.Charts
<SfChart Title="Olympic Medals">
<ChartPrimaryXAxis Title="Countries" ValueType="Syncfusion.Blazor.Charts.ValueType.Category">
<ChartAxisTitleStyle Size="16px" Color="red" FontFamily="Segoe UI" FontWeight="bold"/>
</ChartPrimaryXAxis>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue" Type="ChartSeriesType.Column"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double YValue { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "USA", YValue= 46 },
new ChartData { X= "GBR", YValue= 27 },
new ChartData { X= "CHN", YValue= 26 },
new ChartData { X= "UK", YValue= 26 },
new ChartData { X= "AUS", YValue= 26 },
new ChartData { X= "IND", YValue= 26 },
new ChartData { X= "DEN", YValue= 26 },
new ChartData { X= "MEX", YValue= 26 },
};
}
Axis title alignment
The axis title’s position can be aligned using the TextAlignment property in ChartAxisTitleStyle. The TextAlignment property allows you to specify the alignment of the title relative to the axis. You can set it to Alignment.Near, Alignment.Center, or Alignment.Far to position the title near the start, at the center, or far from the start of the axis, respectively.
@using Syncfusion.Blazor.Charts
<SfChart Title="Olympic Medals">
<ChartPrimaryXAxis Title="Countries" ValueType="Syncfusion.Blazor.Charts.ValueType.Category">
<ChartAxisTitleStyle Size="16px" FontFamily="Segoe UI" FontWeight="bold" TextAlignment="Syncfusion.Blazor.Charts.Alignment.Near" />
</ChartPrimaryXAxis>
<ChartPrimaryYAxis Title="Medal Counts">
<ChartAxisTitleStyle Size="16px" FontFamily="Segoe UI" FontWeight="bold" TextAlignment="Syncfusion.Blazor.Charts.Alignment.Far" />
</ChartPrimaryYAxis>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue" Type="Syncfusion.Blazor.Charts.ChartSeriesType.Column" />
</ChartSeriesCollection>
</SfChart>
@code {
public class ChartData
{
public string X { get; set; }
public double YValue { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "USA", YValue= 46 },
new ChartData { X= "GBR", YValue= 27 },
new ChartData { X= "CHN", YValue= 26 },
new ChartData { X= "UK", YValue= 26 },
new ChartData { X= "AUS", YValue= 26 },
new ChartData { X= "IND", YValue= 26 },
new ChartData { X= "DEN", YValue= 26 },
new ChartData { X= "MEX", YValue= 26 },
};
}
Tick lines
The width, color, and size of the minor and major tick lines can be customized using MajorTickLines and MinorTickLines properties in the axis.
@using Syncfusion.Blazor.Charts
<SfChart Title="Sales History of Product X">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" MinorTicksPerInterval="2">
<ChartAxisMajorTickLines Width="5" Color="blue"/>
<ChartAxisMinorTickLines Width="1" Color="red"/>
</ChartPrimaryXAxis>
<ChartPrimaryYAxis Title="Profit($)" MinorTicksPerInterval="1">
<ChartAxisMajorTickLines Width="5" Color="blue"/>
<ChartAxisMinorTickLines Width="1" Color="red"/>
</ChartPrimaryYAxis>
<ChartSeriesCollection>
<ChartSeries DataSource="@SalesData" XName="X" YName="YValue" Type="ChartSeriesType.Column"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double YValue { get; set; }
}
public List<ChartData> SalesData = new List<ChartData>
{
new ChartData { X= "John", YValue= 10000 },
new ChartData { X= "Jake", YValue= 12000 },
new ChartData { X= "Peter", YValue= 18000 },
new ChartData { X= "James", YValue= 11000 }
};
}
Grid lines customization
The width, color, and dash array of the minor and major grid lines can be customized using MajorGridLines and MinorGridLines properties in the axis.
@using Syncfusion.Blazor.Charts
<SfChart>
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" MinorTicksPerInterval="2">
<ChartAxisMajorGridLines Width="5" Color="blue"/>
<ChartAxisMinorGridLines Width="0.5" Color="red"/>
</ChartPrimaryXAxis>
<ChartSeriesCollection>
<ChartSeries DataSource="@MedalDetails" XName="X" YName="YValue" Type="ChartSeriesType.Column"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double YValue { get; set; }
}
public List<ChartData> MedalDetails = new List<ChartData>
{
new ChartData { X= "USA", YValue= 46 },
new ChartData { X= "GBR", YValue= 27 },
new ChartData { X= "CHN", YValue= 26 },
new ChartData { X= "UK", YValue= 23 },
new ChartData { X= "AUS", YValue= 16 },
new ChartData { X= "IND", YValue= 36 },
new ChartData { X= "DEN", YValue= 12 },
new ChartData { X= "MEX", YValue= 20 },
};
}
Multiple Axis
The ChartAxes is a secondary axis collection that can be used to add “n” number of axes to the chart in addition to the basic X and Y axis. By mapping with the axis unique name, series can be linked to it.
@using Syncfusion.Blazor.Charts
<SfChart Title="Weather Reports">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"/>
<ChartAxes>
<ChartAxis Name="YAxis" OpposedPosition="true"/>
</ChartAxes>
<ChartSeriesCollection>
<ChartSeries DataSource="@WeatherReports" XName="X" YName="Y" Type="ChartSeriesType.Column"/>
<ChartSeries DataSource="@WeatherReports" XName="X" YName="Y1" YAxisName="YAxis"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double Y { get; set; }
public double Y1 { get; set; }
}
public List<ChartData> WeatherReports = new List<ChartData>
{
new ChartData { X = "Sun", Y = 35, Y1 = 30 },
new ChartData { X = "Mon", Y = 40, Y1 = 28 },
new ChartData { X = "Tue", Y = 80, Y1 = 29 },
new ChartData { X = "Wed", Y = 70, Y1 = 30 },
new ChartData { X = "Thu", Y = 65, Y1 = 33 },
new ChartData { X = "Fri", Y = 55, Y1 = 32 },
new ChartData { X = "Sat", Y = 50, Y1 = 34 }
};
}

Inversed Axis
When an axis is inversed, the greatest value on the axis moves closer to the origin, and vice versa. To invert an axis, set the IsInversed property to true.
@using Syncfusion.Blazor.Charts
<SfChart Title="Weather Reports">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
<ChartPrimaryYAxis IsInversed="true" />
<ChartSeriesCollection>
<ChartSeries DataSource="@WeatherReports" XName="X" YName="Y" Type="ChartSeriesType.Column" />
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double Y { get; set; }
}
public List<ChartData> WeatherReports = new List<ChartData>
{
new ChartData { X = "Sun", Y = 35 },
new ChartData { X = "Mon", Y = 40 },
new ChartData { X = "Tue", Y = 80 },
new ChartData { X = "Wed", Y = 70 },
new ChartData { X = "Thu", Y = 65 },
new ChartData { X = "Fri", Y = 55 },
new ChartData { X = "Sat", Y = 50 }
};
}
Opposed position
To place an axis in the opposite position of its original position, set its OpposedPosition property to true. It’s similar to right-to-left (RTL) support.
@using Syncfusion.Blazor.Charts
<SfChart Title="Weather Reports">
<ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"/>
<ChartPrimaryYAxis OpposedPosition="true"/>
<ChartSeriesCollection>
<ChartSeries DataSource="@WeatherReports" XName="X" YName="Y" Type="ChartSeriesType.Column"/>
</ChartSeriesCollection>
</SfChart>
@code{
public class ChartData
{
public string X { get; set; }
public double Y { get; set; }
}
public List<ChartData> WeatherReports = new List<ChartData>
{
new ChartData { X = "Sun", Y = 35 },
new ChartData { X = "Mon", Y = 40 },
new ChartData { X = "Tue", Y = 80 },
new ChartData { X = "Wed", Y = 70 },
new ChartData { X = "Thu", Y = 65 },
new ChartData { X = "Fri", Y = 55 },
new ChartData { X = "Sat", Y = 50 }
};
