Different sort order with line chart and stacked column chart

Question

Hi,
I have a problem with sorting within flash charts.
The chart should be ordered by a date column.
If I'm using a line chart everything is fine. The columns in the chart are in the same order as returned by the query.
If I change the chart type to stacked column chart, I get a wrong order.
It is orderd like 5, 6, 7, 8, 9, 10, 1, 2, 3, 4.
What's wrong?
Here the query i use:
SELECT NULL AS link,
TO_CHAR (zeitpunkt, 'dd.mm.yyyy'),
MAX (DECODE (db_sid, 'TI06E', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI06E",
MAX (DECODE (db_sid, 'TI06T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI06T",
MAX (DECODE (db_sid, 'TI14S', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI14S",
MAX (DECODE (db_sid, 'TI14T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI14T",
MAX (DECODE (db_sid, 'TI16T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI16T",
MAX (DECODE (db_sid, 'TI24K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI24K",
MAX (DECODE (db_sid, 'TI33T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "TI33T",
MAX (DECODE (db_sid, 'WF03E', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF03E",
MAX (DECODE (db_sid, 'WF03K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF03K",
MAX (DECODE (db_sid, 'WF03T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF03T",
MAX (DECODE (db_sid, 'WF05K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF05K",
MAX (DECODE (db_sid, 'WF05T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF05T",
MAX (DECODE (db_sid, 'WF06T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF06T",
MAX (DECODE (db_sid, 'WF07K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF07K",
MAX (DECODE (db_sid, 'WF07T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF07T",
MAX (DECODE (db_sid, 'WF08K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF08K",
MAX (DECODE (db_sid, 'WF08T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF08T",
MAX (DECODE (db_sid, 'WF09K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF09K",
MAX (DECODE (db_sid, 'WF09T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF09T",
MAX (DECODE (db_sid, 'WF10K', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF10K",
MAX (DECODE (db_sid, 'WF10T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WF10T",
MAX (DECODE (db_sid, 'WG04T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WG04T",
MAX (DECODE (db_sid, 'WT05T', VALUE, NULL)) OVER (PARTITION BY zeitpunkt) AS "WT05T"
FROM db_performance_temp
ORDER BY zeitpunkt ASC
SQL> desc db_performance_temp
Name Null? Typ
ZEITPUNKT DATE
DB_SID VARCHAR2(30)
VALUE NUMBER

I found the solution.
Anychart seems to have a problem with null values!
The corrupted sorting only occured for a specific set of search criteria and a specific day. At this day some values have been null.
I added a "nvl( [...], 0) for every value.
No I get a correct sort order.
