How can I draw double Y-axis on a time series plot

I would like to draw these two graphs on a single panel with two y-axes. Does anyone know how?

fcha = timeseries(fch4,time,'Name','CH4');

fchb = timeseries(fco2,time,'Name','CO2');

tsc = tscollection({fcha fchb});

plot(tsc.CH4,'r-')

figure

plot(tsc.CO2,'b-')

You can do with 'subplot' command

[Ilham Hardy]

x = time;
y = fch4;
y1 = fco2;
[ax,h1,h2] = plotyy(x,y,x,y1);
set(h1,'color','r');
set(h2,'color','b');
