Data Labels

Sunburst data labels are used to display the data related to the segment. It helps to provide the information about the data points to the users.
You can enable or disable the data labels by setting the visible property of the DataLabelSettings to true as shown in the below code

  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //...Palette colors
        .DataLabelSettings(dt => dt.Visible(true))
          //...
     )

    Label Overflow mode

    When you represent huge data with data labels, they may intersect each other. You can avoid this using the SunburstLabelOverflowMode property.

    The following properties are used to avoid the overlapping.

    • Trim – To trim the large data labels.
    • Hide – To hide the overlapped data labels.
      The following code shows how to set Hide and Trim mode.
  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //.
        .DataLabelSettings(dt => dt.Visible(true).SunburstLabelOverflowMode(SunburstLabelOverflowMode.Hide))
          //...
     )

  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //.
        .DataLabelSettings(dt => dt.Visible(true).SunburstLabelOverflowMode(SunburstLabelOverflowMode.Trim))
          //...
     )

    Label Rotation Mode

    You can rotate the data label by using SunburstLabelRotationMode property. By default, the labelRotationMode is set as angle.

    The following code shows how to set labelRotationMode as normal and angle.

  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //.
        .DataLabelSettings(dt => dt.Visible(true).SunburstLabelRotationMode(SunburstLabelRotationMode.Normal)
          //...
     )

  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //.
        .DataLabelSettings(dt => dt.Visible(true).SunburstLabelRotationMode(SunburstLabelRotationMode.Angle)
          //...
     )

    Customizing the data labels

    You can customize the appearance of the data point using the Font property.

  • cshtml
  • @(Html.EJ().SunburstChart("chartContainer")
    
         //.
        .DataLabelSettings(dt => dt.Visible(true).Font(font=>font.Color("Black").Font-Weight("Bold").Size("15px")))
          //...
