Pie Chart Sector Color

Question

Hi,
I am using below query to create a flash pie chart. It return count of "RED" , "GREEN" and "YELLOW" from the color field
I used the custom color to color first value as "RED", second as "GREEN" , and third as "YELLOW"
select  null link,
            color ,
            count( color ) value
from table;Above is working fine if all RED , GREEN AND YELLOW ARE GREATER THAN ZERO.
Now if there is no RED in the filed, then PI CHART contain only two region one for Green and second for Yellow.
Problem :--
If red is not there the value representing the count is green is show in red color.
How to avoid this
Thanks

Hi Andy,
I tried the above method but its not working for me..
here is the query which I am using..
DECLARE
vqry varchar(5000);
begin
    vqry := 'select link , LABEL , sum(value) from
(select null link, ''Red'' LABEL , user_id , COUNT(SR_PROJECT.PROJECT_STATUS_ID) value
from  SR_PROJECT where SR_PROJECT.PROJECT_STATUS_ID=1 and
SR_PROJECT.CURRENT_STATUS_ID NOT IN ( 5 , 6) group by user_id
union
select null link, ''Green'' LABEL , user_id ,COUNT(SR_PROJECT.PROJECT_STATUS_ID) value
from  SR_PROJECT where SR_PROJECT.PROJECT_STATUS_ID=2 and
SR_PROJECT.CURRENT_STATUS_ID NOT IN ( 5 , 6) group by user_id
union
select null link, ''Yellow'' LABEL , user_id , COUNT(SR_PROJECT.PROJECT_STATUS_ID) value
from  SR_PROJECT where SR_PROJECT.PROJECT_STATUS_ID=3 and
SR_PROJECT.CURRENT_STATUS_ID NOT IN ( 5 , 6) group by user_id )';
if :P50_PROJECT_OWNER <> 0 OR :P50_PROJECT_OWNER <> NULL THEN
    vqry := vqry || ' where USER_ID = ' || :P50_PROJECT_OWNER;
END IF;
vqry := vqry || ' group by  LABEL ,link';
return vqry;
end;I'm using Function Returning SQL Query. Is this the reason why I'm not able to get the result
