title: How to add icon and label in xAxis values of the horizontal bar chart?
body: <p>I want to add label and icon to the xAxis values in horizontal bar chart like the following image,</p>
  <p><a href="https://i.stack.imgur.com/76Z8y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/76Z8y.png" alt="Graph Image" /></a></p>
  <p>So far I have tired by adding a custom bar icon renderer by using this class <a href="https://gist.github.com/meyerlasse/d560a7be32dfbcefa457c15f1ea6607f" rel="nofollow noreferrer">https://gist.github.com/meyerlasse/d560a7be32dfbcefa457c15f1ea6607f</a> but it doesn't seem to work and it is giving me this error, Attempt to read from null array.</p>
  <p>Any help regarding this issue is appreciated. Thanks.</p>
