GNUPLOT_PLOTPOLAREQUATION

INPUTS :
- ptr_gctrl : Pointer to structure of type gnuplot_ctrl.
- equationstring : Character string (string defining the function to be plotted).
- equationtitle : Character string (title for equation).
OUTPUTS :
- status : Integer (error flag).
PURPOSE :
Plots a specified equation r=f(t) in polar coordinates - invoke gnuplot_setcoordinatesystem first to set the polar coordinate system.
DIAGNOSTICS :
- status = 0 : Success.
- status = BAD_SIGNAL : Called with a dissociated pointer.
- status = -2 : Failed to plot equation.

INTERFACE :

          interface
            integer function gnuplot_plotpolarequation(ptr_gctrl,&
            equationstring,equationtitle) result(status)
              type(gnuplot_ctrl), pointer :: ptr_gctrl
              character(len=*) :: equationstring
              character(len=*), intent(in) :: equationtitle
            end function gnuplot_plotpolarequation
          end interface
