To do this right would also require implementing the subtitle() function.  This, in turn, also requires changing axes objects to add the new properties SubTitle, SubTitleFont, and SubTitleFontWeight.  In addition, as long as the axes object is being changed the TitleHorizontalAlignment property should be added for both Title and SubTitle objects.

Presumably subtitle.m would be mostly a copy of title.m so that wouldn't necessarily be hard.

I think the biggest challenge would be updating the placement routines for plots to account for this extra object between the top margin of the axes, the title object, and then the top of the plot canvas.

The following code now works in Matlab:


plot(1:10);
title('My title', 'my subtitle');


In Octave this throws an error, because the second string argument as subtitle is not supported, yet.

Matlab introduced this additional feature lately in Version R2020b.

I have already received quite a few Matlab scripts that use this feature, because it is a very convinient way to have a two line title. Yes, I know there are other ways to achive this, but people seem to quickly accept this new way of doing it, and I must say I do appreciate the easy way of doing it as well.

In Matlab they also introduced a dedicated function "subtitle" to achive the same thing. (I do not know about their underlying handles and graphics objects...)

Do we want to make Octave also accept this second subtitle string in the title function?
