Line chart to ignore null values

Jeremy WebbAug 9 2013 — edited Aug 27 2013

Hi,

I have a table, RELIABILITY, which holds data for part reliability, so it has the following columns:

REL_DATE,

PART_NO

MTBF

This shows the Mean Time Before Failure for a part. Data is put into the table when a part fails, so there is not necessarily data for every month for a part.

I want to create a line chart which shows this, with lines connecting the points.

The problem I have is that say I have the following data:

REL_DATE - 01-JAN-10

PART_NO - APART

MTBF - 10

REL_DATE - 01-MAR-10

PART_NO - APART

MTBF - 20

If I chart this, I get two points mapped correctly, but because there is no data for 01-FEB-10 it does not join the points up. Bear in mind this is a very simplified example.

Is there anyway to tell APEX to ignore the "null" data for 01-FEB-10, and join up the points for JAN and MAR, so that at FEB it the line would go through 15 for MTBF?

Ideally I want to be able to do this without having to calculate a dummy value of 15 for FEB, as I would rather not put a point there as there is no actual data.

Any ideas?

Regards,

Jez.
