Arduino U8glib: how to display text?
Just choose a smaller font. You know, I showed you the documentation earlier. You really should read it, because it contains all the information you need.

For instance, here is the section on the available fonts: https://code.google.com/p/u8glib/wiki/fontgroup - each section contains a link to download the font group which of course you will need to do before you can use it.

You might find something like:

u8g.setFont(u8g_font_fixed_v0);


more to your liking. And don't forget to download it via the link above first.
