ORDER BY in line chart with more than 1 lines

Question

Hello,
I created a line chart and added 3 chart rows. The x-axis shows the calendar week, which should be ordered.
It works perfectly with only one row, but if I add a 2nd or a 3rd row and execute it, the chart shows nothing and stays blank.
If I delete the "ORDER BY KW" for each row the x-axis is mixed up.
Here is my SQL:
select null link, KW label, SUM(SNDG) value
from "TBL_FB_SNDG_FRTTR"
WHERE SEND_KZ = 'Z'
group by KW
order by KW
Can anybody help me?
Thanks so much,
LISA

Answer 1

I found a solution:
- create a VIEW which is ORDER BY KW
- use this VIEW instead of the table for the chart
- remove the GROUP BY
Now the SQL:
select null link, KW label, SNDG value
from "VIEW_FB_FTTR_SNDG"
WHERE SEND_KZ = 'Z'
Before I tried it by using the GROUP BY and it did not work ... why it works without it - I don't know. ;-)
