Interactive use of DISLIN

[Andrej Dzerzhinsky]

I'm building a scientific app using wxPython to call some C functions
together with a suitable plotting application that will work within a
wxPython frame.

I'd like to plot a spline over several thousand (x,y) points from a
spectrum, reasonably fast, and be able to zoom in and out of the plot,
label peaks either automatically or by hand, display and overlay
multiple data sets and export plots as metafiles.

Platform independence is also a big plus.

Examining several of the Python plotting packages (BLT, matplotlib,
pyplot, hippodraw, DISLIN), so far DISLIN seems to offer the best
combination of speed and ease of use, with matplotlib coming a close
second.

Can anyone comment on whether DISLIN can be made to do the interactive
things I have mentioned. http://www.openboa.de/srd/node8.html claims
it can't - is this accurate?

Or is matplotlib or some other package better for what I want.

Thanks for your time.
