[Gnuplot-bugs] problem in parametric mode

[Mike L. <yo...@ya...>]

Gentlemen,
   
  If you want to plot in parametric mode (set angles degrees) the ellipse X(t)=1.5*cos(t-45), Y(t)= sin(t-45),  you get just a horizontal ellipse.  The 45 degree phase shift is not seen by the program!
   
  If you reverse the positions in the argument to (-45+t), you get a single point .7071, -.7071!
   
  Clearly, when an argument (  ) is presented in parametric mode, the program sees only the first element in the argument and nothing else!
   
  Is there any way of overcoming this?  Is this a known issue in Gnuplot?
   
  Thank you.
   
  Sincerely,
