Fwd: Fwd: Maxima Graphik



Dear list,

the problem described below still persists.  The graphic occasionally and
very irregularly is not displayed on the screen but stored in the file

  C:/Users/Ziegenbalg/maxout_2.png
This is annoying in general and in particular when it happens in a
presentation.
It happens on various computers with  Maxima 5.31.2 /  wxMaxima 13.04.2
under Windows.
If anyone has an idea as to what might be the cause and how to avoid this
behaviour, please let me know.

Thank you,
Jochen

P.S.: The analogous thing happens with wxdraw2d.
P.P.S.:  What I found out:  when I use  plot2d  and  draw2d  instead of the
wx-versions of these commands, it seems to work fine, but then new windows
are opened for the graphics.  For documentation purposes I would prefer the
wx-commands to work as the are supposed to do.

Dear
list,

w
hen using wxplot
I
sometimes
 
get the graphic wanted, but occasionally (but not always and not
predictably) I get the following strange result.

Example:

<<< new cell >>>  

FL :
[[0,0],[1,1],[2,1],[3,2],[4,3],[5,5],[6,8],[7,13],[8,21],[9,34],[10,55],[11,89],[12,144],[13,233],
[14,377],[15,610],[16,987],[17,1597],[18,2584],[19,4181],[20,6765]]

<<< new cell >>>  

wxplot2d([discrete, FL]);

*Output (instead of the graphic):  *

  wxxmltag(C:/Users/Ziegenbalg/maxout_2.png, img)

If you have an idea as to what might be the cause, please let me know.
I use

Maxima 5.31.2 with wxMaxima 13.04.2 under Windows.

Thank you very much,
Jochen Ziegenbalg
