Thread: [Matplotlib-users] Plot array of arrays

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I have been struggling with this all afternoon.  I have a function which
generates an array of arrays:

y=[array([<f(x0)>]),array([<f(x1)>]),array([<f(x2)>])...]
and x=array([x0,x1,x2,...])

I want to plot the family of curves y=f(x).
plot(x,y[n]) where n is the nth array in y plots the correct curve,
however plot(x,y) and plot(x,y[:]) complain about mismatched array
dimensions.

Any suggestions?
Thanks,
Dave

Might you want
plot(x,y.transpose())

Alan,

Thanks for the help.  This was a big clue.  It turns out that what I
thought was an array of arrays was actually a list of arrays.  If my
list was y, running plot(x,array(y).transpose()) solved the problem!

Thanks for your help,
Dave
