Bar Graph Help (removal of zero values)

Hi,

I have a series of bar graphs (approximately 20 in total) and each one
is linked to a set of 5 data points (i.e. 5 point data scale). For
some of the points the value is zero and this is showing up
intermittently on my bar graphs - I want to get rid of the zero values
however I am producing approximately 500 reports and don't want to do
it manually. Can anyone help me/ provide and suggestions.

Thanks in advance for your reply.

Kind regards,

Heather
