Subject: [Tioga-users] how to change the padding of whitespace around a
	figure?
Message-ID: <b133af800810120406s32b0943as4996dc0ef35a8dd8@mail.gmail.com>

Hi all,

Another tioga question (I've been looking at the documentation and web for
an hour, but couldn't find an answer that worked). The graphs I am currently
making do not have axis labels, titles or legends outside the figure. As a
result, there seems to be quite a lot of whitespace around the figure
itself. I am quite sure that one of the many options Tioga has allows me to
reduce that whitespace, but although I meddled with pagewidth, framesize and
bounds, I couldn't figure out how to.

Please enlighten me :).

Hi,

This sort of thing is most easily done in your "enter_page"  
function.  For example, in samples/plots/plots.rb, you'll find a  
defintion for "enter_page" which sets page width and height after  
first calling set_default_plot_style.  The definition of  
set_default_plot_style is found in plot_styles.rb in the same  
directory.  In that routine you'll find it setting page size and  
margins.

     # Page size and margins
     # these default values are used by the default_enter_page_function

     t.default_page_width = 72*5.5 # in big-points (1/72 inch)
     t.default_page_height = 72*4.25 # in big-points (1/72 inch)

     t.default_frame_left = 0.15 # as fraction of width from left edge
     t.default_frame_right = 0.85 # as fraction of width from left edge
     t.default_frame_top = 0.85 # as fraction of width from bottom edge
     t.default_frame_bottom = 0.15 # as fraction of width from bottom  
edge


The frame_left/right/top/bottom values set the margins.

Cheers,
Bill
