title: How to set a custom x axis 0 label in charts ios
body: <p>I am using <a href="https://github.com/danielgindi/Charts" rel="nofollow noreferrer">Charts by Daniel Gindi</a></p>
  <p>How can I set a String 0 label on x Axis? I want it to show &quot;Now&quot; instead of a Date type.
  I've seen the function that helps to format one particular label only, but I can't get how it works. Moreover, I haven't seen any examples of it. So, how does <code>getFormattedLabel(index: Int)</code> work?
  This is what I need my xAxis to look like:
