Tooltip

ToolTip allows you to display any information over a sunburst segment. It appears when mouse hovered over or touch any chart segment. By default, it displays the corresponding segment category name and its value

  • js
  • <ej-sunburstchart  id="sunburst"   [tooltip.visible]="true" >
    </ej-sunburstchart>

    Tooltip Template

    HTML elements can be displayed in the tooltip by using the tooltip.template property of the tooltip. The template property takes the value of the id attribute of the HTML element. You can use the #point.x# and #point.y# as place holders in the HTML element to display the x and y values of the corresponding point.

  • js
  • <body>
    <div id="Tooltip" style="display: none;">
            <div id="value" style="background-color:red;padding-top:3px;padding-right:3px">
                <div>
                    <label id="efpercentage" style="color:white">
                        &nbsp;&nbsp;Category:&nbsp;#point.x#
                       <br />&nbsp;&nbsp;Value:#point.y#
                    </label>
                </div>
            </div>
        </div>
