Thanks Regina

I have found your reply and the original question of Sebastián interesting and useful. I had a similiar issue just recently, but did not ask for any help as it was not an urgent task to do in a spreadsheet, just experimenting, now at least I am aware of the limitations, and interestingly of Gnumeric's use. I never realised the dot points of the screen width, mine 1920, having an effect, I was playing with 2000 data points.

Nice, one learns more every day.

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

It seems like Calc cannot manage these charts quickly. Each modification
takes a long time to be accomplished.

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

I've have try these same type of chart in gnumeric and it works very fast.
Is this the normal functioning of calc?

I'm running the suite LibreOffice 4.0.4 in Ubuntu, with an I7 processor.

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
