Product: cantor
Version: 21.12.2

Status: REPORTED
Severity: normal

Mentioned octave script
SUMMARY
Using Octave's plot function results in nothing being shown.
STEPS TO REPRODUCE
1. write an Octave script
2. use plot()
3. Run in cantor
OBSERVED RESULT
There are 2 cases.
- if plot integration is enabled, the cell is reported to be "calculating"
forever, nothing is shown.
- if it's disabled, computation terminates straight away and still nothing is
shown.
EXPECTED RESULT
Script tested in Octave, works as intended.

ADDITIONAL INFORMATION
See and test the attached script.
After investigating suggested related bug reports, I found out that changing
the Octave backend from the default "octave-cli" (yes, this is still the
default) to "octave" or even "octave-6.4.0" makes plots appear.
Still, disabling plot integration makes plots disappear again.
