Help with Graph

Question

Hi All
In a report i have field called "CERTIFY" and it has two values 1 and 2. Based on this i create a calculation:
CASE WHEN DW_MDSS_ROUTE_SO_POST.CERTIFY = '1' THEN COUNT(DW_MDSS_ROUTE_SO_POST.CERTIFY) WHEN DW_MDSS_ROUTE_SO_POST.CERTIFY = '2' THEN COUNT(DW_MDSS_ROUTE_SO_POST.CERTIFY) ELSE NULL END
The above calculation gives me the count of records when "CERTIFY" is 1 and 2 as two different bars.
Now i have a second field called"DEVIATION" and its a text field. It has values only when "CERTIFY=2", what i wanted in the report is in the graph i want two bars "COUNT WHEN 1 AND WHEN COUNT IS 2" and in the COUNT BAR FOR 2 , i want to seperate the COUNT based on the DEVIATION " I want DEVIATION AND COUNT" as a STACKED bar.
Thanks

Sorry, Thinking Eye. This is not an answer. However, it may help to get your question answered if you show how some example data look in tabular or cross-tabular form and then state which columns or rows you wish to graph as bars and how you want them grouped. It would also be helpful if you could do it in SQL*Plus in case anyone wanted to try it out on their system. This would include create table, insert, and select statements to show the result set of data you wish to plot. As in:
SQL>CREATE TABLE t
  2     ( certify INT,
  3       deviation VARCHAR2(30)
  4     );
Table created.
SQL>INSERT INTO t VALUES ( 1, NULL );
1 row created.
SQL>INSERT INTO t VALUES ( 1, NULL );
1 row created.
SQL>INSERT INTO t VALUES ( 2, 'LEMON' );
1 row created.
SQL>INSERT INTO t VALUES ( 2, 'ORANGE' );
1 row created.
SQL>INSERT INTO t VALUES ( 2, 'LIME' );
1 row created.
SQL>SELECT certify
  2         , deviation
  3         , CASE
  4             WHEN certify = 1 THEN COUNT(certify)
  5             WHEN certify = 2 THEN COUNT(certify)
  6             ELSE NULL
  7           END AS cnt
  8    FROM t
  9  GROUP BY certify, deviation;
    CERTIFY DEVIATION                              CNT
          1                                          2
          2 LIME                                     1
          2 LEMON                                    1
          2 ORANGE                                   1
4 rows selected.Now since the following query gets the same results, you'll need to explain why you are using that CASE statement.
SQL>SELECT certify
  2         , deviation
  3         , COUNT(*) AS cnt
  4    FROM t
  5  GROUP BY certify, deviation;
    CERTIFY DEVIATION                              CNT
          1                                          2
          2 LIME                                     1
          2 LEMON                                    1
          2 ORANGE                                   1
