How to create a chart in Qt?

[QtBegginer]

Hello fellows ;-)
First of all i'd like to say I'm just a beginner in Qt.

I'd like to create a line chart in my program and i'm pondering how to do this...
I was thinking about QChartView but i afraid it's only for commercial ;-(.
Is there any easy way to creat nice chart in Qt for free?

Have You any examples of code? I just begining my adventure with Qt and i'm a little bit confused.

Thanks in advance.
Best regards!

Take a look at Qwt

I found Qwt exceedingly difficult to use. I ended up using QCustomPlot instead.
It's relatively easy to use, it has many examples, and it's fully documented.

Qwt is definitely an option.

I can not fully agree with:

I found Qwt exceedingly difficult to use.

BUT:
Qwt is a lot more difficult to use because of its limited documentation. I have some experience with other plotting libraries and the Qwt interface is a lot better for me regarding plotting. It is a bit sad that all this power is lost through sometimes difficult to understand classes, due to the lack of documentation.
