A lot of our college students are using Openoffice for financial reasons (and
because it's simple and powerfull) but there is a major lack in Charts creation
that keeps us to OfficeXP and that could lead, if fixed to the migration to
Openoffice. 
Sciences labs always include charts with statistic about it's. The problem is
mainly about the lack of regression types: 
polynomial, and moving average which are included with excel xp(as well as
power, linear, exponential and logarythmic). Opening a .DOC document containing
a chart with polynomial regression doesn't makes the chart display correctly.

Also, the possibility to include the formula to of the regression line as a part
of the chart would be nice instead of using Linest() , etc. functions.

Thanks for considering that request. We hope to hear about it in the future
releases of Openoffice, making big publicity for the project in the college;).
