Problem with Gantt table (Business graphic)

Question

Hi everybody,
I got a problem with an gantt table (Business graphic) in an old project. This gantt table is used to display the timeline of used ressources. The Problem here his that, if the last row of the gantt table is filled, this row will not be displayed correctly. The line will only be filled up half of the height the row has and the row will be divided by a horizontal black line.
If somebody has an idea about fixing this problem, that will be great.

Great!
Of course, hard to diagnose when there's nothing to see.
Here's an old message in a thread from 2010. (To give credit, it's from Hilary Farrell.)

You are correct, the syntax outlined in the error message is incorrect, and I've logged bug 9799373 to track this. As a workaround, you can view sample syntax for Gantt charts on the 'Query' page of the Create wizard, in the 'Chart Query Example for Gantt' Show/Hide region below the text area for entering your chart query, and also in the Oracle APEX 4.0 User's Guide that will be available with our new release. Just in case other users hit the same issue and are unsure of the expected format:
Chart Query Examples for Project Gantt Charts:
SELECT NULL LINK,
TASK_NAME NAME,
TASK_ID ID,
NULL PARENT_ID,
START_DATE ACTUAL_START,
END_DATE ACTUAL_END,
STATUS_NUMBER PROGRESS
FROM TASKS
SELECT 'f?p=4000:2:'||:APP_SESSION||':::P2_ID:'||ID LINK
TASK_NAME NAME,
TASK_ID ID,

FROM TASKS

SELECT NULL LINK,

NULL NAME,
NULL PARENT_ID,
START_DATE ACTUAL_START,
END_DATE ACTUAL_END
FROM TASKS
SELECT 'f?p=4000:2:'||:APP_SESSION||':::P2_ID:'||ID LINK
RESOURCE_ID ID,
RESOURCE_NAME NAME,
PARENT_ID PARENT_ID,
START_DATE ACTUAL_START,
END_DATE ACTUAL_END
FROM TASKS
Thanks for reporting this issue, and I'm happy you were able to successfully generate your chart.

Can you show us the query you are using?
Oh. And what are the data types and lengths of your data?
