Description Xisco Faulí 2013-05-23 12:40:08 UTC

Created attachment 79703 [details]
sample with 66000 points in the chart

Description from #i121058 (https://issues.apache.org/ooo/show_bug.cgi?id=121058):
Open the sample file with large chart, it takes too much time on loading, looks like freeze. And sometimes a warning dialog pops up with warning msg "Main memory shortage. Please quit other applications or close some windows before continuing.", click "OK" button on this dialog, then pops up an error dialog and AOO crashes.

AOO solution isn't that good because it only works for numeric data, not for text data. Besides, as Kohei suggested, it should be done in the chart engine, not in calc

Thank you for your bug report, I can reproduce this bug running libreoffice Version: 4.1.0.0.beta1
Build ID: 3a2c2d2417101e45fe07cfd8358acf2204a98f3 on Mac osx 10.8.3 
and version 4.0.3.3.

Loading does take like 2 minute and I get the spinning wheel on my mac. 
Wen I look at my system use LibreOffice uses 98.9% of my cpu. after loading just 0.2%

It's the same problem with version 3.6.7.2. May be from Aoo?

I am wondering how this chart was created, as when I was trying to create a chart from data which contains 10K+ rows, it's really slow, and when you try to rezise the chart, calc will freeze.

Also, when attachment 79703 [details] finished loading finally in Calc, if you scroll, there is secious lag/delay. There is a saperate bug report regard this issue: Bug 81230. I added as see also.
