Axis Customization in Blazor Chart component

20 Apr 2021 / 2 minutes to read

Axis Crossing

An axis can be positioned in the chart area using CrossesAt and CrossesInAxis properties. The CrossesAt property specifies the values (datetime, numeric, 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.

@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 Crossing

Title

You can add a title to the axis using Title property to provide quick information to the user about the data plotted in the axis. Title text can be customized using TitleStyle property of the axis.

@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 Customization

You can customize the width, color and size of the minor and major tick lines, using MajorTickLines and MinorTickLines properties in the axis.

        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

You can customize the width, color and dasharray of the minor and major grid lines, using MajorGridLines and MinorGridLines properties in the axis.

Grid Lines Customization

Multiple Axis

In addition to primary X and Y axis, we can add n number of axis to the chart. Series can be associated with this axis, by mapping with axis unique name. See also

        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 }
    };
}

Multiple Axis

Inversed Axis

When an axis is inversed, highest value of the axis comes closer to origin and vice versa. To inverse the axis set this property IsInversed to true.

    public List<ChartData> MedalDetails = 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 }
    };
}

Inversed Axis

Opposed Position

To place an axis opposite from its original position, set OpposedPosition property of the axis to true.

        new ChartData { X = "Fri", Y = 55 },
        new ChartData { X = "Sat", Y = 50 }
    };
}
