Your screen has likely not more than 2000 dots width. Are you sure you 
need 25000 data points?

That is true. Opening such documents is a problem too, especially with 
xsl import filter.

It is a shortcoming in LibreOffice and Apache OpenOffice. There exists 
already an internal point reducing for identical points. But the problem 
still remains. I would generate the chart from a reduced set of data 
points with less than 10000. And never try to use 3D charts on such huge 
set of data points.

Kind regards
