That's not to be expected.
To be honest, my tweaking session was some months ago and I fiddled round a lot.
We had around 1000 graphs of that type, so I needed a software solution quite
badly. I ended up tweaking some tables, as I did not see a neat coded solution
and expected this to be a corner case. Perhaps I'll have to make up my mind
again to dig deeper. But it's definitively an ugly part.
I'm quite sure, that after my solution was implemented, the graphs custom data
were as expected. I'll try to figure out next days as I'm currently off-campus.
