body: <p>I am migrating chart.js to 3.x as per the migration guide.<br />

  <p>I am trying to set the xAxis zeroLineColor to &quot;#FFFFFF&quot; and I want to have the Grid line color as &quot;#00FFFF&quot; but as per the chart.js migration document document <code>scales.[x/y]Axes.zeroLine* options of axes were removed. Use scriptable scale options instead</code>.</p>
  <p>I am not sure how to use scriptable scale options for setting the xAxis line zero to white.</p>
  <p><strong>Update:</strong><br />
