Of course, you can do it. I have updated the codepen: https://codepen.io/samuellawrentz/pen/mjqmVZ

You just have to pick a point from the series data and then fire the select event on it during chart load. The condition to pick which point to be selected during load must be specified.

For now, I have hard-coded the 6th point to be selected during page load. Check out the codepen for details.

EDIT:

As you requested, I have updated the codepen,have a look. The value to be selected during click is given as a value attribute in the HTML. Then during the click event we are reading that attribute and selecting the point that was mentioned in the value attribute.

<p class="num" value=5>10</p>

Here 5th point will be selected when you click on 10 as the value of the value attribute is 5.
