I found that it happens because newer plotting capability is provided by access to OpenGL. The function call graphics_toolkit ("fltk") selects the FLTK/OpenGL. If I switch to gnuplot it work properly.

The switch to the new version was really terrible. 1. The prints of plots are not generated if they are not displayed, making all scripts useless. 2. The title strings do not respect endlines '\n' 3. Titles are written over the plot 4. scatter3 rotations (views) do not work well in fltk, and not at all in gnuplot. 5. The legend is malformed and put at a wrong place. That really hurts. octave-3.8.2-9.fc21.x86_64
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
