title: Show/hide point label Androidplot
body: <p>When my chart gets a lot of data the point labels overlap each other and as a result I want to give the user an option to turn them off by clicking a button but I can't find anything in the documentation on how to do this. Below is how I setup the point labels when the chart is created.</p>
  
  <pre><code>BarFormatter series1Format = new BarFormatter(Color.rgb(51, 181, 229), Color.TRANSPARENT);'
  PointLabelFormatter  plf = new PointLabelFormatter();
  plf.getTextPaint().setTextSize(18);
  plf.getTextPaint().setColor(Color.BLACK);
  series1Format.setPointLabelFormatter(plf);
  </code></pre>
