I have created a column chart with 4 columns with 2009 data. I want to add
overlay markers over those columns. Those markers will be the 2008 data. I
have done this in the past by adding the data/xy scatter graph and so forth,
but it was a long time ago and I do not remember the steps. I have tried to
paste special the data to adding those columns but cannot seem to remember.
Any help is appreciate. Thanks
