getslope
Slope of the current line.
Description `

    getslope displays the equation of the current line of the figure. Use
    the menu 'Insert > Line' to draw a line first. getslope allows for
    rough curve fitting "by eye". Use the shortcut Ctrl+G if the Ezyfit
    menu is installed (see efmenu).

    Depending of the axis types, the equation of the line will be:
         Y = N*X+A         for X linear and Y linear
         Y = A*X^N         for X log and Y log
         Y = A*EXP(N*X)    for X linear and Y log
         Y = A+N*LOG(X)    for X log and Y linear (LOG = natural logarithm)

    [N, A] = getslope also returns the parameters N and A of the equation.

    [N, A] = getslope(OPT) specifies the display mode:
         'eq'       displays the full equation (by default).
         'slope'    displays only the slope N.
         'nodisp'   displays nothing.
