help plotyy

PLOTYY Graphs with y tick labels on the left and right.
    PLOTYY(X1,Y1,X2,Y2) plots Y1 versus X1 with y-axis labeling
    on the left and plots Y2 versus X2 with y-axis labeling on
    the right.

    PLOTYY(X1,Y1,X2,Y2,FUN) uses the plotting function specified by
    the string FUN instead of PLOT to produce each plot.  FUN
    should be a plotting function like 'plot','semilogx','semilogy',
    'loglog','stem', etc. that accepts the syntax H = FUN(X,Y).

    PLOTYY(X1,Y1,X2,Y2,FUN1,FUN2) uses FUN1(X1,Y1) to plot the data for
    the left axes and FUN2(X1,Y1) to plot the data for the right axes.

    [AX,H1,H2] = PLOTYY(...) returns the handles of the two axes created in
    AX and the handles of the graphics objects from each plot in H1
    and H2. AX(1) is the left axes and AX(2) is the right axes.  

    See also PLOT.
