title: MPAndroidChart, how to center XLabels above grid-lines?
body: <p>I have a simple linechart with <a href="https://github.com/PhilJay/MPAndroidChart" rel="nofollow noreferrer">MPAndroidChart library</a>:</p>
  
  <pre><code>chart.setDrawYValues(false);
  chart.setDescription("");
  chart.setDrawVerticalGrid(true);
  chart.setDrawGridBackground(false);
  
  XLabels xl = holder.chart.getXLabels();
  xl.setCenterXLabelText(true);
  xl.setPosition(XLabelPosition.BOTTOM);
  
  YLabels yl = holder.chart.getYLabels();
  yl.setLabelCount(5);
  
  // set data
  chart.setData((LineData) mChartData);
  
  chart.setDrawYValues(true);
  chart.setValueTextSize(20f);
  
  // zooming on both axis
  chart.setPinchZoom(true);
  chart.animateX(1000);
  </code></pre>
  
  <p>But I have a visualization problem. Labels on the X axis aren't under the relative grid line, but between the two lines (on Y axis I don't have this problem). Is there a way to put Y labels exactly under the relative grid line?</p>
