What is the best way to draw charts in c++ ?? So far I've been using external program (gnuplot) to draw charts. I generated a configuration file and file with data to draw. However I think it's not the best solution. What is in Your opinion the best library to draw charts in c++??
A chart is not really a well defined output format. In a way the bunch of numbers sent to gnuplot are already a kind of chart.
To answer to your question you should define what you mean by chart : some image with a given format ? some html source code ? etc.

I am making a 3D renderer using Win32 and GDI and currently working on importing .obj files.
What is the best way to display a file explorer where the user can choose an .obj file and close the dialog. ( and store the file name/location in a string for me to use) ?
You can use good old GetOpenFileName function: http://msdn.microsoft.com/en-us/library/windows/desktop/ms646927%28v=vs.85%29.aspx. For Vista and later you can use Common Item Dialog: http://msdn.microsoft.com/en-us/library/windows/desktop/bb776913%28v=vs.85%29.aspx

I am making an open world 3d platformer in Ogre3D, and I have no idea on what kind of 3d map file format I should use for it.
I want to make low-polygon blocky-style objects. Probably rectangles and other geometrical figures that don't have circular edges. Some of those blocks will have properties, like climbable or they might move.
I was wondering what would be the best thing to do to make the map without recurring to making a map format and a map editor
Look at this: http://www.ogre3d.org/tikiwiki/DotScene
Ogre 3d has it's own .scene format. You probably want to do it in this format.

I have implemented some algorithms from graph theory in C++. My teacher wants us to show some examples with graphs, so I need to draw a graph and then explain step by step how my implementation works.
I don't want to use paint for this job so I was wondering is there any tool available that can make your life easier when trying to create weighted graphs with edges and vertexes?
thanks!
Yeah, use graphvis. If you're already using boost.graph for your implementation you can simply write your graphs to graphvis format.

I'm developing an Android application and I need to use a render engine to show some objects that I made with Blend.
I'm wondering if there is a C++ game engine or render engine to show my models.
Is there anyone?
Thanks.
Yes. Take a look at http://www.cuteandroid.com/open-source-android-2d-or-3d-game-engine-for-android-developers-plus for game engines.
Just for rendering, it looks like this might help: http://www.rozengain.com/blog/2010/05/17/loading-3d-models-with-the-min3d-framework-for-android/

Is there any open-source or free chart library for Qt? I only need XY charts, not bar charts or anything else.
QCustomPlot is a rather compact Qt widget for plotting, with the possibility of extension to your needs, under the GPL license. It has no further dependencies and is fully documented, including internal functions.
Check the QCustomPlot website.
There's two I know of:
Qwt
QtiPlot: the app is paid, but the code is not I think (you can download the source)
KD Chart
