Use Plotyy(t,A,t,B).

type
help plotyy

Hi, I want to plot two dataset on a same plot, i.e, not subplot(2,1,1)...subplot(2,1,2)
But the two datasets are with different range, A is (1,100) ,B is (0.001, 0.1).
If I simply "hold on" and plot one by one, data in B are barely visible. How to solve that problem?
Thanks a lot.

From the MATLAB Help:

The XAxisLocation and YAxisLocation properties specify on which side of the
graph to place the x- and y-axes. You can create graphs with two different
x-axes and y-axes by superimposing two axes objects and using XAxisLocation
and YAxisLocation to position each axis on a different side of the graph.
This technique is useful to plot different sets of data with different
scaling in the same graph.

Look up "Using Multiple X and Y Axes" in the online help & it'll give you an
example.
