title: Telerik RadChart labeling and positioning
body: <p>I'm new to Telerik Chart controls and I have some minor problems:</p>
  
  <p><img src="https://i.stack.imgur.com/IRCvU.png" alt="My chart">
  (1) I want to set the (1, 2, 3, 4) in the horizontal axis into ("a", "b", "c", "d")<br>
  (2) The legend stays at the top of the chart</p>
  
  <p>Please tell me how to do it.</p>
