[Octave-bug-tracker] [bug #45865] text not rendering when plotting

[Rik]

Follow-up Comment #4, bug #45865 (project octave):

There was a typo in the code I sent.  It needed a closing parenthesis to
execute.  Now that we know it is OpenGl only, try


close all
graphics_toolkit qt
text (0.5, 0.5, "0.1 0.5 Hello World 0.75 1.0")


One possibility is the font that was selected is not particularly well
rendered for some reason.  You could attempt to force it to a known good value
with the set() command.  Sample code:


close all
graphics_toolkit qt
plot (0:3);
set (gca, "fontname", "FILL_IN_A_GOOD_FONT")


On Linux you should be able to get a list of fonts available by using 


fc-list


from a shell command line.
