MATLAB: Axis for Plotyy for Multiple plots

axismultiple plotsplotplottingplotyy

Hello,
I'm using Plotyy as
[haxes(1:2),hline1,hline2] = plotyy(x1,y1,x1,y2);
set(haxes(1:2),'NextPlot','add');
plot(haxes(1),x1,y3,'-r','LineWidth',1.5)
plot(haxes(2),x1,y4,'-blue','LineWidth',1.5)
%Now I'm setting for a Region of Interest(ROI) plot
axis([28 38 -1000 1000])
The Problem is when I set the axis, it is showing the zoomed/ ROI of the last 2 plots of y3 and y4, but not the ROI for y1 and y2. (Its not setting the axes automatically for the x1,y1 and x2,y2) Please suggest me how to proceed. Thanks in Advance

[hAx,hL1,hL2] = plotyy(x1,y1,x1,y2);
set(hAx,'NextPlot','add')
plot(hAx(1),x1,y3,'-r','LineWidth',1.5)
plot(hAx(2),x1,y4,'-blue','LineWidth',1.5)
linkaxes(hAx)                          % key missing ingredient...link the axes you want same
axis(hAx(1), [28 38 -1000 1000])       % now all axes in hAx will stay in synch with hAx(1)
