This may be a bit early, since the array functionality was only released 
so recently, but I've been trying to use arrays to replicate the 
functionality of plotting a multi-column file.

For example, if I have the following data.dat :

-90., -1.30e+01
-60., -3.78e+01
-30., -1.66e+01
0., -5.61e-03
30., -1.66e+01
60., -3.78e+01
90.,  -1.30e+01

And do plot "data.dat" then I get a graph we're all familiar with.

What I've come up with, to replicate using arrays, is :

array plt[7] = [ {-90., -1.30e+01}, {-60., -3.78e+01}, {-30., 
-1.66e+01}, {0., -5.61e-03}, {30., -1.66e+01}, {60., -3.78e+01}, {90., 
-1.30e+01} ]
plot plt u 1:2

But it doesn't give me what I expected.

I would welcome any thoughts.

Thanks very much,
John
