draw chart in Qwidget

Question

I want to draw a simple line chart in my QWidget application. I found this link, but when I add `

#QT += charts

to my .pro file, an error appear that :

Unknown module(s) in QT: charts

As you can see at the bottom of the linked page, the module is available only under certain Qt licenses — Fabio, May 03 '16 at 06:09
@Fabio Is there any other simple and free component or other thing to draw chart in qt? — mjyazdani, May 03 '16 at 06:42

You may use QCustomPlot. It's free (GPL), simple (just 2 files), fast and well-documented.

GPL can be a limiting factor for some applications. Alternatively Qwt is available under LGPL, which allows closed-source dynamic linking. – Archie May 03 '16 at 11:59

You may use Qt Charts (it is free, qt blog), but you need cloning git repository and building the project manually. Git repository you can find here.

It's free only from Qt 5.7. It is now only in alpha version. – Dmitry Sazonov May 03 '16 at 11:15
