TDBChart avg problem again

Hi,

I am refomulating my problem of an earlier post, since it seems I was not clear enough about my problem:

I am using a DBChart like in the Features Demo, Database Charts / Summary Grouping / Summary Order. If in the summary properties I choose Avg for the summary calculation, then NULL values of the linked Dataset go into the average computation. This of course leads to false results. Hence again my question if I can make the summary calculation to ignore NULL values.

Sorry for posting here again, but it seemed my other post was not clear enough.

TIA

Markus

Hi Markus,

yes, this feature has not been yet implemented, it's on our wish list as a feature request to be considered for further releases.
In meantime the only workaround I can think of would be to calculate the summaries manually.

Thanks Pep,
that's what I thought.
So I will calculate the averages manually and, unfortunately, then add them manually to a TChart.
