+<h3>Access and Update a <code>Chart</code> Instance's Axis.</h3>
+
+
+<p>Often times, you will need to update a chart after it has been rendered. This example demonstrates how to access and update an axis. Specifically, we'll update the rotation and color of
+the axis labels.</p>
+<p>A <code>Chart</code> instance's axes can be accessed through the <code>getAxisByKey</code> method. This method takes the axis' key identifier as an argument. If you have explicitly set your
+axis through the <code>axes</code> attribute, you will know the key identifier. If not, the default key identifier for the value axis is "values" and the default key identifier for the category
+axis is <code>category</code>. Once you have a reference for the axis, you can update all of its public attributes.</p>
