This is an ugly hack but it at least works. This regression has been
introduced by the merge from the AOO code. The order of calls during
import is totally screwed and I have no idea how to properly fix all
these problems without introducing new regressions.

The best solution would be to move the import/export code into chart2
where we could manipulate tese properties directly and would not need to
transform the same information N times until it is written into the
chart code.
