Hi, On this subject, one program that has pretty impressive interactive visualisation is the venerable snd (http://ccrma.stanford.edu/software/snd/). It displays hours of audio in a flash and allows you pan and zoom the signal without a hitch. It only plots an envelope of the audio signal at first, and shows more and more detail as you zoom in.
Jimmy's comment that there's no need to visualize 3 million points if you can only display 200 000 is even more true for time signals, where you can typically only display 1000 to 2000 samples (i.e. the number of horizontal pixels). Does the new path simplification code use a similar approach to snd? I've always wanted something like that in matplotlib... :-) Regards, Ludwig ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Matplotlib-devel mailing list Matplotlib-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-devel
