This is a forwarded report from the Debian issue: https://bugs.debian.org/845612 ---- Package: kalgebra Version: 4:16.08.3-1 Severity: normal Start kalgebra, choose "3D Graph". Either use one of the examples, or enter a formula like "x*y", press <Enter>. Graph gets plotted. Now change the formula to eg. "x+y", press <Enter>. Graph doesn't show any surface any more, only the axes. Even reverting to the previous formula doesn't help - no new data will be plotted ---- Additionally, using with the example: t->vector{t,t**2,t}, somehow kalgebra does manage to redraw this particular plot, somehow I think that this is managed by analitza in a different way. Happy hacking,
I also have this issue, just looked at the code and it's _really_ weird. :/
The same problem spotted in KAlgebra 0.10 for openSUSE Leap 42.2
Git commit e10d40be86b1b27e3506c478ed28add7ffcb4ef3 by Aleix Pol. Committed on 14/02/2017 at 23:58. Pushed by apol into branch 'master'. Consider Plotter3D, the non-OpenGLES version, deprecated It wasn't working well (see reported bug) and it is essentially duplicating effort.

Use PlotsView3DES to render 3D plots Uses the same code we use on the mobile version, which doesn't have the reported bug.
