Chart creation -- What am I missing here?

[KevinTheDBA]

I have tried to create a chart - any, it really doesn't matter which - and failed.

I am using a very simple SQL statement. It is as follows.

SELECT TB.REPORT_DATE
,TB.AVG_FREE_SPACE_PER_PAGE
FROM TABLEB TB

I am simply trying to generate a line graph using the AVG_FREE_SPACE_PER_PAGE as the X and the Report_date as the Y.

This is not working for me however. Have I missed something? The functionality seems very straightforward as does the documentation.

I follow it to the letter and my graphs appear completely blank, or with non-varying lines.

Please advise.

Kevin,

Not sure why it's failing on you. I installed V7.0.0.1050 a few days ago and get decent results from the following query:

SELECT trunc(created) create_date, COUNT(*) obj_count
  FROM user_objects
GROUP BY trunc(created)

Yep.. Had it fixed immediately after I pressed the "post" button...

However - I would like to have two lines, because infact there are two related items along the timeline that I would like to graph.

I take it this is not presently supported?
