suppress zeros in a pivot chart
 

Is there anyway to suppress the zeros in a pivot chart? My pivot table shows
activities for many different queues, and sometimes a particular queue won't
have a value for an activity that another queue has. When i chart just this
queue, the activity shows up as 0%. I don't want to delete the label, because
then when i change to another queue that DID have that activity, the value
won't show up.

Any thoughts?
thanks!
