Point Constraint Values Unreadable, Increase Size

[Beuk]

Hello, 

Whenever I print to pdf, the point constraints result plot lose part of its resolution, making them close to unreadable. Is there a way to increase the font size of those particular fonts bigger?

I have tried playing around with these config parameters with no luck:

default_ui_font 10
text_height_factor 40.000000
model_tree_font 10

I managed to change the fonts of the menus, but the point constraint values stay the same.

I don't know how to change the font size,

but I always use measured values on springs to ground for bearing reactions.
