title: Gscatter for 3 variables
body: <p>I am working on Discriminant Analysis and would like to classify some data using MATLAB. In the example of Fisher's Iris Data as given in MATLAB (visit <a href="http://www.mathworks.com/products/demos/statistics/classdemo.html" rel="nofollow">www.mathworks.com/products/demos/statistics/classdemo.html</a> for details), they consider only the first 2 variables (Sepal Length &amp; Width). I would like to proceed with classification with more features such as Petal Length and Petal Width.</p>
  
  <p>Also, the MATLAB function gscatter seems to take only 2 variables.</p>
  
  <p><code>gscatter(meas(:,1), meas(:,2), species,'rgb','osd');</code></p>
  
  <p>I would like to include meas(:,3) as well and proceed. Kindly help me. Thank You</p>
