So, I have implemented my PyQt4/veusz application, which can be seen here:
http://mmmccormick.com/#tcd_analyze
It looks good, but the speed is not usable for a real dataset. I've
got anti-aliasing turned off, which helps a lot, but it still needs a
ways to go. Here is some profiling data I made with the cProfile
module:
In [1]: import pstats
In [2]: p = pstats.Stats('dwl_profile.dat')
In [3]: p.sort_stats('time', 'cum').print_stats(10)
