title: mxGraph diagrameditor change label position
body: <p>I'm editing the digrameditor in <a href="https://github.com/jgraph/mxgraph/blob/master/javascript/examples/editors/" rel="nofollow noreferrer">here</a>! for my own project and I need to position the labels of the vertices to bottom. I tried by adding follow changes but seems it's not the case.</p>
  
  <pre><code>....
  // Program starts here. The document.onLoad executes the
  // mxApplication constructor with a given configuration.
  // In the config file, the mxEditor.onInit method is
  // overridden to invoke this global function as the
  // last step in the editor constructor.
  function onInit(editor)
  {
       // Set align of the labels to bottom
       mxConstants.STYLE_VERTICAL_LABEL_POSITION = mxConstants.ALIGN_BOTTOM;
  ....
  </code></pre>
  
  <p>Any help?</p>
  
  <p>Thanks.</p>
