title: I am getting decimal number in place of whole number
body: <p>I am getting decimal number on the y-axis of a bar chart as (0.0, 0.5,1.0,1.5,2.0 and so on).</p>
  
  <p><img src="https://i.stack.imgur.com/uZ3Ed.jpg" alt="enter image description here"></p>
  
  <p>this is set a mask for the value axis labels. </p>
  
  <pre><code>&lt;axisFormat tickLabelMask="0.0" verticalTickLabels="false"&gt;
                          &lt;labelFont/&gt;
                          &lt;tickLabelFont/&gt;
                      &lt;/axisFormat&gt;
  </code></pre>
  
  <p>I want whole number in place of that (1,2,3,... and so on). How is it possible??</p>
