chart dynamic row count Content

hi i want to change the row count dynamically in run time with if conduction

if     rowCount="{count(xdoxslt:group(current-group(),  'GRP'))}"   grater than or equal  5 so the row count will be 5

if     rowCount="{count(xdoxslt:group(current-group(),  'GRP'))}"   less    than 5 so the row count will be the same of {count(xdoxslt:group(current-group(),  'GRP'))}

thanks
