Public bug reported:
Binary package hint: qtiplot
What I expected to happen: A quick plotting of my data.
What happened instead: Everytime I try to plot some big table (i.e.
100K+ rows), qtiplot freezes for several minutes. And worse: if I edit
something, the re-plot takes the same unnecessary amount of time.
Sincerely, this almost makes me give up of qtiplot, but today I
accidentally discovered that this precious plot time could be
drastically reduced by disabling "antialiasing" in the menu Format>Plot.
This turns the "lots of freezed minutes" in "some few (non-freezed)
seconds"!
So, concluding, I highly recommend that the antialiasing be DISABLED by
default, so other people do not pass the same trouble I've been
experiencing for months...
BTW, my system configs are:
$ uname -a
Linux valadao-desktop 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:57:31 UTC
2009 i686 GNU/Linux
$ cat /etc/issue
Ubuntu 9.04
$ apt-cache policy qtiplot
nautilus:
Installed: 0.9.7-1
Candidate: 0.9.7-1
