Unfortunately, the explanation I found was for an older version of Excel, and
a bit short on detail when trying to do it in Excel 2007 - the "up-down bars"
include the min and max for each quintile (when I only want them to run from
the 1st to 4th quartiles), and I cant find out how to change their spread.
They also COVER all the markers, and I cant find how to bring the markers to
the front.
Any help greatly appreciated - thankyou!
