Re: [libreoffice-users] Charts with lots of data in Calc

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.

Regards
