GNUPLOT_PLOTSLOPE

INPUTS :
- ptr_gctrl : Pointer to structure of type gnuplot_ctrl.
- a : Real (in a*x+b).
- b : Real (in a*x+b).
- xlo : Real (lower limit of xrange) (optional) ignored if a previous plot exists.
- xhi : Real (upper limit of xrange) (optional) ignored if a previous plot exists.
- slopetitle : Character string (title for slope).
OUTPUTS :
- status : Integer (error flag).
PURPOSE :
Plots the specified slope line.
DIAGNOSTICS :
- status = 0 : Success.
- status = BAD_SIGNAL : Called with a dissociated pointer.
- status = -1 : Called with invalid range (if present).
- status = -2 : Failed to plot slope.
- status = -4 : Missing one of the two xrange specifications (if present).

INTERFACE :

          interface
            integer function gnuplot_plotslope(ptr_gctrl,a,b,slopetitle,&
            xlo,xhi) result(status)

              real(dp), intent(in) :: a,b
              real(dp), intent(in), optional :: xlo,xhi
              character(len=*), intent(in) :: slopetitle
            end function gnuplot_plotslope
