Not able to change font size of legend

[vpadulan]

Dear @jenegger,
I would say that line spacing cannot be customized, according to this post

Hatching - how to keep same spacing between lines

indeed the line spacing depends on the pad size because these pattern are drawn using normal line. You can see the same effect if you grow and shrink the canvas. The line spacing adjust according to the canvas size. That something special to these patterns and might be useful in some cases.

and the fact that TAttText class doesn’t provide a function to set the line spacing (docs).
Best,
Vincenzo
