#2886 draw2d(points(data)); - Error

[Rene Hansen]

data : makelist([x, random(1)], x, 1, 10, 1);
draw2d(points(data)); gives no graph, but the error:

[gr2d(points)]
wxdraw2d(points(data));

Gives just an "error" image

Did you enter the commands manually or were they loaded from a file?

[Rene Hansen]

The above commands where keyed in manually

In the other bug reports, the commands where stored in a .wxmx - file created using an previous version

[Rene Hansen]

When I enter it manually - it works

When I try load (lsquares) two times - it seems to work the second time

The others seems to work afterwards, when they are entered manually in an empty worksheet the first time...

[Rene Hansen]

The above seems to be true with all the packages I have been using:

load(fmin_cobyla);
load (lsquares);
load("draw");
load("simplify_sum");
load(interpol);
load (graphs);
load("fft");

However
load (lsquares);
Reported an error during the first compilation:

Back to wxdraw2d(points(..))

When I try to save an existing wxmx fie as an xmx file and reload that one, the plot(points(..)) dosen't work.

When copying the commands needed to do the plot into an fresh wxMaxima worksheet, the plot works. Wierd ??

[Andrej Vodopivec]

This is a duplication of bug #2628.
