I've got a cross-tab table where the field are summarized as "percentage of count of field1" . In this cross-tab, the fields  appears as percentage  (10% , 15 % etc..).

 

I'm using this cross-tab to create a chart  "on cross-tab,select insert chart"

 

The problem is: on the chart the table values are not showed as percentage, but only like 10, 15 , instead of 10% , 15% etc..

 

I've tried to format this field but with no success, any idea how can i put the % on the chart ?
