<h3>Update Series of a <code>Chart</code> Instance After It has Rendered.</h3>
<p>You can update a series after the <code>Chart</code> has rendered through the <code>getSeries</code> method. This method returns a reference to a series instance based on either the
instance's <code>seriesCollection</code> index or the key value associated with the value data of the series. This example uses the value key of each series to update the fill color,
border color and border weight of its markers.</p>
