I am trying to plot variables in C++ inside a for loop. In Matlab, it is very easy, just type plot(x,y), but I do not know how to use it in C++. Is it possible to do it with opencv? or if anybody has a better recommendation I really appreciate it.
If you want high quality plots take a look at gnuplot (can be used from C++ program) or asymptote (you can generate script and use this script for render your plot), but these tools are not for dynamic plotting.
Use the cvplot library, it will provide matlab style plotting function in opencv. You can also use this library.

i'd be interested in a c++ (if any) library to handle and elaborate 3d video files. I need to process the NifTI and Analyze format.
Thanks
You should use opencv for video processing. It is a very good library for processing video and you can also edit video. It provides a lot of inbuilt functions to process video.

Currently I'm working in a simple code generator to output an assembly-like language.
Background:
I've already working part of a register allocator but now I need to deal with instructions like mul/div which has fixed registers as input: eax/ebx which I don't know how to deal with it, so I'm looking for see how other implemenations does it. I've tried tcc. While the code is very small I find a bit hard to understand.
NOTE: I'm targeting C/C++ because it's the languages I'm more familiar with, but implementation in any language is very welcome.

Does anybody knows some free or not free library for converting svg to raster image (preferably to png).
I see that there are ImageMagic, GraphicMagic, librsvg. But I can't to figure out how to use them or are suitable to my issue. I need to do trasformation programmatically from my code.
The canonical library to render SVG is librsvg.
You may want to check that out.

maybe someone knows a good crossplatform particle library?
I know Pyro particle library, but it's not crossplaftorm and free. There is also Magic Particles (Probably, the best version I need) but there is only theoretical possibility to make a port on Linux.
I'm not sure how good it is, but I remember seeing a post on www.gamedev.net on a open source particle engine written in C++. It appears to be graphics-library agnostic, so you should be able to easily port it to whatever platform you are interested in.
Here's a link:

Can anybody recommend a good (ideally open source) C++ spell checker library. We are currenly using Talo, which isn't very good, so we are looking to change.
One which includes a grammar checker would also be good.
Thanks
I have heard good things about hunspell. I have used and integrated aspell, which has some nice features and some which I did not like.
If you've got internet access, you can always use on online service like SpellCheck.net which has a CGI interface that you can query.
