Axis in Essential ASP.NET MVC Chart

13 Jun 202324 minutes to read

Charts typically have two axes that are used to measure and categorize data: a vertical (y) axis, and a horizontal (x) axis.

Vertical axis always uses numerical or logarithmic scale. Horizontal(x) axis supports the following types of scale:

  • Category
  • Numeric
  • DateTime
  • DateTime Category
  • Logarithmic

Category Axis

Category axis displays the text labels instead of numbers. To use the categorical axis, you can set the ValueType property of the axis to the Category. Default value of ValueType is Double.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Use categorical scale in primary X axis
              px=>px.ValueType(AxisValueType.Category)
         )
            // ...
        )

    Place labels on ticks

    Labels in the category axis can be placed on the ticks by setting the LabelPlacement property of axis to the onTicks. The default value of the LabelPlacement property is betweenTicks i.e. labels are placed between the ticks, by default.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Placing X-axis labels on the ticks
              px=>px.LabelPlacement("onTicks")
         )
            // ...
        )

    Display labels after a fixed interval

    To display the labels after a fixed interval n, you can set the Interval property of the axis range as n. The default value of the interval is 1 i.e. all the labels are displayed.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Displaying labels after 2 intervals
              axis=>axis.Range(range=>range.Interval(2))
         )
            // ...
        )

    Indexed Category Axis

    Category axis can also plot points based on index value of data points. Index based plotting can be enabled by setting IsIndexed property to true in the axis.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
                //...
                .PrimaryXAxis(px=>px.IsIndexed(true))
                    .Series(sr =>
                    {
                        //Adding Candle series
                        sr.Points(pt=>{
                            pt.X("Monday").Y(50).Add();
                            pt.X("Tuesday").Y(40).Add();
                            pt.X("Wednesday").Y(70).Add();
                            pt.X("Thursday").Y(60).Add();
                            pt.X("Friday").Y(50).Add();
                            pt.X("Monday").Y(40).Add();
                            pt.X("Monday").Y(30).Add();
                        }) .Add();
                    })

    Apply padding to the range

    Padding can be applied to the minimum and maximum extremes of the axis range by using the RangePadding property. Numeric axis supports the following types of padding

    • None
    • Round
    • Additional
    • Normal

    None

    When the value of the RangePadding property is None, padding can not be applied to the axis. This is also the default value of the rangePadding.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryYAxis(

    ####Customizing the starting range of the axis

    By default the Y axis will be always calculated from the value 0 for column, bar, stacking column and stacking bar series types. You can modify this behavior by setting false to the property StartFromZero in the axis. On setting this the axis minimum value will be calculated based on the value for the data points.

  • CSHTML
  • @(Html.EJ().Chart("container")
            .PrimaryYAxis(axis => axis.RangePadding(ChartRangePadding.None).StartFromZero(false))
        )

    Common axis features

    Customization of features such as axis title, labels, grid lines and tick lines are common to all the axis. Each of these features are explained in this section.

    Axis Crossing

    Axis can be positioned anywhere in chart area using the CrossesAt property of axis. This property specifies where the horizontal axis should intersect or cross the vertical axis and vice versa. Default value of CrossesAt property is null.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Crosses primary Y axis at 0
              px=>px.CrossesAt(0)
                  //....
         )
            // ...
    	)

    Axis Crossing in ASP.NET MVC Chart

    Crossing a specific Axis

    The CrossesInAxis property takes axis name as input and determines the axis used for crossing. By default all the horizontal axes crosses in primary Y axis and all the vertical axes crosses in primary X axis.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Crosses secondary vertical axis at -0.2
              px=>px.CrossesAt(-0.2)
    		        .CrossesInAxis('SecondaryYAxis')
                  //....
         )
            // ...
    	)

    Crossing a specific Axis in ASP.NET MVC Chart

    Axis will be placed in the opposite side if value of CrossesAt property is greater than the maximum value of crossing axis (axis name provided through CrossesInAxis property or primary Y axis for horizontal axis).

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Crosses primary Y axis at 200
              px=>px.CrossesAt(200)
                  //....
         )
            // ...
    	)

    Crrosses in axisin in ASP.NET MVC Chart

    Positioning the axis elements while crossing

    The ShowNextToAxisLine property is used for controlling the axis elements movement along with the axis line while axis crossing is performed. When the showNextToAxisLine is set as false only the axis line and the tick lines are placed at the crossing Value and the axis elements will be placed outside the chart area. The default value of ShowNextToAxisLine is true.

  • CSHTML
  • @(Html.EJ().Chart("chartContainer")
    
          // ...
    
         .PrimaryXAxis(
              //Crosses primary Y axis at 0
              px=>px.CrossesAt(0)
              .ShowNextToAxisLine(false)
                  //....
         )
            // ...
