Gruff: Adjustment of font and labels

Rails
1

Hi,
My graphs are working properly except two things:

  1. The font of the “title” is way to big and so gets cropped and
  2. On X-axis I want to display my labels which are varchars. But again
    because of the limitation of the graph size it is overlapping on one
    another.

I can increase the graph dimension but it doesn’t look good. Any ideas
on

  1. How to reduce the font
  2. Is there any way instead of horizontal I can place my labels
    vertically?

Please let me know.

Thank you.
