Tooltip Template

HTML elements can be displayed in the tooltip by using the template option of the tooltip. The template option 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.

<div id="item" style="display: none;">
    <div>
        <div>#point.x#</div>
        <div>#point.y#</div>
