you can use grouping, so:

<begin of chart>
<some cells>
\start
<some settings>
<some cells>
\stop
<etc>

has to do with auto splitting charts

although technically you can downscale charts it's best to use a smaller 
body font (if you have you dimensions related to bodyfontsize) since this 
will leave thinsg like hyperlinks ok (in pdf hyperlinks are on a different 
layer which is not subjected to scaling [which in my opinion is a design flaw])

you can clip a portion of a chart, say that you have a 10 by 20 chart, 
x/y/nx/ny == 2/4/3/3 let you select a 3 by 3 piece of it.
