Hello everyone,
I need to use Dragon NaturallySpeaking on Windows 2000 and I haven't
yet gotten a compiler working on this system. Pardon any odd looking
text because my voice dictation software quite often inserts the wrong
word. Just in case you can't tell yet, I am a Ruby newbie and I
apologize for asking rudimentary questions. Please feel free to just
tell me where to go :-). Literally, the ulr would be terrific.
My goal is to have my application plot arrays of (x,y) and possibly
(x,y,z) data points in "real time". I would also like to write text
on the graphs. I would like to ask for a knowledgeable comparison and
contrast of the multitudes of graphic utility libraries out there
capable of doing this seemingly SIMPLE plotting.
=== Please comment on the following ===
Because of all your help, I have had some great successes with the
following:
Tcl and tk - I don't know to draw lines in this library yet and the
windows look slightly different than I expect.
WxRuby - I don't know how to draw lines yet in this library.
spreadsheet-0.2.8.tar using win32ole - I would like to embed Excel in
my Ruby code.
FXRuby - this looks like an excellent possibility however, this looks
a bit more complicated than OpenGL. It looks like I have to draw
everything and I don't know how to easily write text on the graphics I
create. I.e. I believe have to draw the axes.
OpenGL - this looks like an excellent possibility. It looks like I
have to draw everything good and I don't know how to easily write
text. I.e. I believe have to draw the axes.
=== Please comment on the following if you have Windows 2k successes
I have also had limited success with the following libraries ending in
a show of my ignorance with POSIX OSs, cygwin or using compilers on
Windows:
Rmagick - object not loading properly
SVG::Graph - does not generate graphics directly
ROOT - way to comprehensive for now
PGPLOT - POSIX
Narray POSIX
rgl-0[1].2.1 POSIX
TkGnuplot-0.1.tar POSIX
ruby-graphviz_0.2.0.tar POSIX
gp400win32 - I'm not sure how to call the libraries.
I greatly appreciate all of the assistance and pointers you have been
giving me!
Thank you,
Todd

WxRuby - I don't know how to draw lines yet in this library.
In WxRuby you could use a Device Context to draw lines, points, fills, ellipses, etc, plus text onto a frame. For a full list of methods available see the WxWidgets docs:
http://www.wxwidgets.org/manuals/2.4.2/wx105.htm#wxdc
I haven't used these classes in detail, so I don't know whether the bindings are complete, but the following simple example worked for me using wxruby-0.3.0 (current release is 0.4.0)

Hello Alex,
While that's pretty easy. Thanks for showing me that!
