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

I am looking for a class to export my c++ functions and classes to lua and call C++ functions from lua.
I have found few but I am interested in user impressions over usability/ stability / community support.
So if you used such a wrapper please help.

I'd like to know what is the best and faster way to write a GUI in C++.
In the past I've created my GUI with just Windows API.
Now I'd like to read some suggestion about other libs like GTK , MFC , QT ecc.
Thanks :)
Use Qt. It's powerful and easy to use, also, it's cross-platform. If I need a GUI for C++, I always go for Qt.

I have decided to start learning Qt C++ and HTML5
Please somebody provide some good step by step tutorials about Qt HTML5
Or demos
http://doc.qt.io/qt-4.8/
Best Qt knowledge center ever :)
Qt and HTML5 are a little distant: Qt is from the Desktop Federation and HTML5 is of the Web Republic, but if you'd like to combine them, you might be interested in QtWUI.

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.
