The backend command is only for gnuplot and fltk (the official builtin

every such package has its own way to become active or inactive.

For example if you have installed jhandles you enable it with

pkg load jhandles

I do not know if the following is still true for plplot-octave, but a long
time ago the command to enable/disable it was:

toggle_plplot_use

at the octave prompt.

does any one know how to solve this problem?

https://bugs.launchpad.net/ubuntu/+source/octave3.2/+bug/546671

when I ran backend('fltk') in octave 3.2.2 with Ubuntu 9.10,
things worked ok. But when I ran it in octave 3.2.4 on
another Ubuntu 10.04 box, I got the "_ZTV15opengl_renderer"
undefined error.

thanks
