Created attachment 71820 [details] This is a file for testing. The procedure is explained in the bug report Problem description: When trying to resize a xy scatter plot with large amount of data (two plots with 4096 rows in my case), the program freezes and/or takes a large amount of time to complete the action (if it ever gets completed). It should not be the case in a core i7. Operating system Debian wheezy and running under KDE. Steps to reproduce: 1. Create a xy scatter (only lines) plot with large data 2. Resize the plot. 3. The program freezes 4. The attached spreadsheet can be used. Add to a plot scatter plot xy (only lines) with two sets of data: - x values: J5 to J4100 - y1 values: B5 to B4100 - y2 values: M5 to M4100 Expected behavior: The size of the plot should change in a few seconds maximum and not staying idle using 100% workload on a single core for long time (sometimes more than 10 min). Operating System: Debian Version: 3.5.4 release
Thank you for reporting this issue! I have been able to confirm the issue on: Version: 4.2.0.0.alpha0+Build ID: b0a1666f756aa5f5315366eca9d7d02ddd55d2b Date: Tue May 28 08:51:01 2013 +0300 Platform: Bodhi Linux 2.2 x64 + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Per discussion with Markus, this is a known issue that's essentially caused because every resize redraws the points. Anything past about 1000 rows can cause issues with smoothing. What I can confirm: Creating the original scatter plot is quite slow (maybe good to have an attachment with it already made) On my system (dual core 64bit,2.2 ghz, 4 gigs RAM, it's been 10ish minutes and still just calculating stuff) Resizing will have the same issue since it's just recreating it from scratch essentially. Marking as: New (confirmed) Minor - doesn't prevent high quality work but definitely can slow it down substantially High - 1000 row threshold is quite low for professional power users. But fix is probably going to be tough and require substantial code changes.

It would be better to have an example file.
