It could also be great to insert fields related to the current graph ! For
example, in writer, we can insert fields related to the current document (name,
path...). It would be a nice feature to be able to insert in a document fields
pointing to an inserted diagram. Example of fields :

- title
- x title
- y title
- label

calculated fields :

- specific value of a series
- sum, max, min, product...  of specific values of a series
- sum, max, min, product...  of the values of a series
- sum, max, min, product...  of the values of more than one series


This should work for any diagram in any of the OOo module.

- This should work in a diagram copied in Writer.
