Is it possible to do in a chart ?

Question

Hi All,
after long time i return to develop apex application.
it's good to be back even if it's for one little project.
i created a query that returns the top 5 wait events per day
you can see the output here:

i want to show it in apex in a chart.
i tried using stacked chart but with no success.
i want to see for each day the top 5 wait events .
how can i do it ?

Denes,
I'm so excited about this thread because I thought this was a lost cause - didn't think it was possible to dynamically display series in a Flash Chart. I hope you can help me.
I have a table FILESYSTEMS with columns host_id (varchar2), label (varchar2), sample_date (date), available (number).
For a given host, I want to display in a 2-D line chart all the corresponding filesystems (i.e where host_id = :P63_CHOOSEHOST).
I can't hardcode the series queries ahead of time because each host has different filesystem labels, and different quantities of filesystems associated with the host.
Currently the user must select the host, then the individual filesystem (label) but that is cumbersome - a chart that shows them all is desirable.
Here's the working query for one series:
select null link, SAMPLE_DATE label, AVAILABLE as value1
from FILESYSTEMS
where host_id = :P63_CHOOSEHOST
and sample_date >= (sysdate-365)
and to_char(sample_date,'DY') = 'MON'
and label = :P64_LABEL
order by sample_date I looked at your example PL/SQL code but as I am not a developer, I can't figure out how to rework it for my situtation. I got this far...
DECLARE
   v_query   VARCHAR2 (4000);
BEGIN
   v_query := || 'SELECT NULL link, sample_date, ';
   FOR c in (select distinct label from filesystems
             where host_id = :P63_CHOOSEHOST)
   LOOP v_query :=
     v_querybut I dont' know how to translate the rest to return the data I'm wanting to chart: available space over time (sample_date) for each filesystem.label on the host.
