title: wpf toolkit chart rotate axis
body: <p>How do  you rotate the text in the axis from horizontal to vertical?</p>
  
  <p>I cant do it through xaml because I am a creating multiple series on the fly and I do not know up front how many I will have until after the control populates.</p>

  <p>I need to display the dates vertical or at a slant and not horz.</p>
  
  <p>Thank you again.</p>
