title: When formatting x-axis labels in Ng Apex Chart(Angular), x-axis labels are duplicated
body: <p>I'm using Ng Apex Charts. <br>
  In <strong>X Axis label</strong> the showDuplicates property is set to false because I dont want duplicated x-axis labels.
  <br> <br> My data values in x-axis are 0.4, 0.7, 1.2, 1.3, 2, 2.4</p>
  <blockquote>
  <p>I'm using <code>xaxis &gt; labels &gt; formatter</code> function to show only integer values, no matter what data value it is and this is working fine, but the problem is the labels are shown duplicated like this: 0,0,1,1,2,2.</p>
  <p><strong>The result I want to be is: 0, 1, 2 in x-axis labels.</strong> <br/></p>
  </blockquote>
  <p>Is there any solution? <br/>
  Thank you.</p>
