Scale Maps for Printing
Maps are often printed at a size that makes objects on paper a particular fraction of their real size. The linear ratio of the mapped to real object sizes is called map scale, and it is usually notated with a colon as "1:1,000,000" or "1:24,000." Another way of specifying scale is to call out the printed and real lengths, for example "1 inch = 1 mile."
You can specify the printed scale using the
It modifies the size of the printed area on the page to match the scale. If the
resulting dimensions are larger than your paper, you can reduce the amount of empty
space around the map using
by changing the axes position to fill the figure. This also reduces the amount of memory
needed to print with the
zbuffer (raster image) renderer. Be sure to
set the paper scale last. For example,
set(gca,'Units','Normalized','Position',[0 0 1 1]) tightmap paperscale(1,'in', 5,'miles')
paperscale function also can take a scale denominator as its
first and only argument. If you want the map to be printed at 1:20,000,000, type
To check the size and extent of text and the relative position of axes, use
previewmap, which resizes the figure to the printed size.
