title: achartengine Legend issue
body: <p>I am using achartengine for drawing a chart in my app. So far the chart is drawn succesfully. the only problem i have is when i try to remove the legends. As for my app I feel I do not want the legends. So I used </p>
  
  <pre><code>renderer.setShowLegend(false);
  </code></pre>
  
  <p>and it did takeaway the legends but it also takes away the x axis labels. can anybody tell me what is happening? or where i am doing mistake.</p>
  
  <p>i tried adding </p>
  
  <pre><code>renderer.setDisplayChartValues(true); 
  </code></pre>
  
  <p>but it does not do anything.</p>
