Cluster Bar charts

Question

HI,
I have a cluster bar chart that runs well with one query. The problem occurs when you add more than one series. I get an SVG Chart error ORA-20001 The only differenece is that the second and third series would have a distinct[b] resolution_type. Has someone run across this issue? I have pasted my query below:
SELECT NULL l
, MON
, MAX(resolution_type) resolution_type
FROM ( SELECT TO_CHAR(stat_date,'MM/YY') mon
, NVL(COUNT(status), 0) resolution_type
FROM ht_issues
WHERE category = 'Help Desk Issue'
AND resolution_type = 'Functional'
and trunc(stat_date) between to_date(:P14_RPT_DATE, 'dd-mon-yy') - 27 and to_date(:P14_RPT_DATE, 'dd-mon-yy')
GROUP BY TO_CHAR(stat_date,'MM/YY')
UNION ALL
SELECT DISTINCT TO_CHAR(stat_date,'MM/YY') mon
, TO_NUMBER(NULL) resolution_type
FROM ht_issues
GROUP BY mon
Any help would be appreciated,
Thanks,
Wally

Answer 1

The SELECT statement you have is still only defining one series. You do not use UNION ALL to add a second series to a cluster bar chart. Use the "Add Series" button in the "Chart Series" to add your "SELECT DISTINCT TO_CHAR(stat_date,'MM/YY') mon , TO_NUMBER(NULL) resolution_type FROM ht_issues" query. Each series needs to be defined separately with its own SELECT statement.
