What I am about to ask will probably sound trivial to
an experienced user, but I have spent quite some time
on it.
Say that I saved some data in a Nx2 array like:
y x
0.05 0.0039
0.10 0.0014
0.15 0.0033
0.20 0.0066
I would like to plot them (1st column: dependent
variable, 2nd independent variable).
I can create two lists correponding to the 2 colmns of
the matrix e.g.:
L_y:makelist(Matrix[i,1],i,1,N);
, but on the Maxima manual, it seems that the element
of the lists in open_plot have to entered as
[[x1, y1, x2, y2, ...] or [[[x1, y1], [x2, y2], ...],
...] , which is not what I have in mind.
Since the 2 columns can be very long, I cannot simply
type in the list of values.
Furthermore, can Maxima save the 2 columns both
separately and together in order to be read as a
matrix by another plotting tool?
Regards
Lorenzo
