Hi,

Recently, I have installed PLPLOT 5.1. = with Octave.=20 This plot tool is promising.

However, I would like to know more = about=20 Octave/plplot setting and column format, cause i meet = trouble.

First, with plplot_octave_demo, demo = x01c and x03c=20 abort with dimension mismatch in dimension x.

In a last mail (11 Mar 2002), Douglas = Eck wrote to=20 John W. Eaton :

The plplot demos = do not run=20 with my configuration with prefer_column_vectors =3D = 0
=20 (debian sid running octave-plplot and latest 2.1 octave packages)=20

    The problem is = somewhere in=20 plplot_octave.oct and so I'm not getting a trace.
    = I'm sure=20 it's an easy fix but I don't have time today to track it down.=20 Basically
    x and y need to be column=20 vectors.

With, prefer_column_vectors set to 1, I = can note=20 that plplot_octave_demo run.

But, i meet trouble with my own data, = like : (x and=20 y, geographical coordinate)

x =3D 400=20 000 y=3D 4 000 = 000

400=20 100 4 = 000=20 100

400=20 200 4 000=20 200

=20 ... &nbs= p; =20 ....

N=3Dlength(x) ( with = length(x)=3D=20 length (y)=3D 2000)

If i call plpoin (N,x, y) : Octave say = "dimension=20 mismatch in argument x called from 'plpoin' "

If i call plline (N,x,y) : Octave say = "dimension=20 mismatch in argument y called from 'plline' "

My octave setting are :

PS1 =3D ">> "
= PS2 =3D=20 ""
beep_on_error =3D 1.0
default_eval_print_flag =3D = 0.0
default_save_format =3D "mat4-binary"

gnuplot_has_multiplot =3D 1

implicit_str_to_num_ok =3D = 1.0
=20 ok_to_lose_imaginary_part =3D 1.0
page_screen_output =3D = 0.0

prefer_zero_one_indexing =3D = 1.0

treat_neg_dim_as_zero =3D = 1.0

whitespace_in_literal_matrix = =3D=20 "traditional"

Many thanks for your hint.

Best regards.
