i'm surely off by one in my understanding of the plot command, as i
expected a sine in figure 1 and a cosine in 2, while what i got was a
blank figure 1 and both the sine and the cosine in figure 2

can anyone help me? tia

I don't know why but this works fine.
f1=figure(1)
plot(sin(linspace(0,10)),figure=f1)
f2=figure(2)
plot(cos(linspace(0,10)),figure=f2)
show()

You're also likely to get more answers if you ask on the mailing list 
here https://lists.sourceforge.net/lists/listinfo/matplotlib-users.

it works as well (with a proper t...)

plot(sin(t);figure(2);plot(cos(t));show()

because that's the way it is advised to do

in help(plot) one can read that in the named  arguments that are
accepted from plot, you can say also figure=figurehandle, but it is
evident that i misundertood the issue

another mailing list?  really i have to? <smilies, lots of>

You can set the current figure to fig1 with the following:

    figure(fig1.number)
    plot(...)

Alternatively, you can use the plot methods of a particular axes:

    fig1 = figure()
    ax1 = axes()
    fig2 = figure()
    ax2 = axes()

    ax1.plot(...)
    ax2.plot(...)

It works the same for subplots:

    fig1 = figure()
    ax11 = subplot(211)
    ax12 = subplot(212)
    fig2 = figure()
    ax21 = subplot(211)
    ax22 = subplot(212)
 
    ax12.plot(...)
    #etc
