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. |
