This looks potentially very interesting. I have a few comments on the demo
on the above site.
1. The octave front-end applet (the one where only the help button works)
didn't work at all on my Netscape: it just froze Netscape.
2. The demo of plotting sin(x)./x was OK. I hope one can easily adjust
thngs like line thickness and line style, etc. I like the zoom
facility and the slide-bar for sliding the window along the graph.
Useful for time-series work and the like. A zoom-slider (to allow a
contuously variable zoom factor) would be a very nice addition.
4. It must be remembered that nothing of this kind will cope with the fact
that octave has (as yet) no built-in code for contour generation or
for surface-plotting with hidden lines, since the code for computing
these is not in octave but in gnuplot (or in whatever other
contour/surface capable package one uses instead of gnuplot -- this is
one reason why I like using PlotMTV which is rather good at these
things).
5. I did not manage to obtain any useful java code (maybe I muffed the
"store" operation under netscape). Is there a URL for downloading the
java code?
6. I suppose that the applets will run OK
Also, I only managed to run the sin(x)./x plot applet once. After I
had to restart netscape (due to above hang) I failed several times to
reload the full applet (netscape said it could not find the plotting
class). Maybe this is my Netscape being a bit shaky, but I'd have felt
better about the thing if this had not happened.
7. Re the low speed mentioned by Oscar Marquez: presumably it wold be
possible to get higher speed by running it directly under java in
stead of thtought Netscape?
By all appearances a promising path to follow. May we hear more, please?
