Well, there's Qt Charts module, which are part of the commercial license. If you don't have such a license you could either google for some widget or write it yourself (it's a pretty simple widget to make).

says
"the Qt Add-ons licensing will be changed so that the Qt Charts module becomes available under both GPLv3 and commercial license terms."

so should be usable with GPLv3 also ?

There are also

For Qt 5.7 as far as I understand it.

Yes the QtCharts Module is available with GPLv3.
I have already compiled it on my own.

The question was if anybody has experience with that module and can give me an short advice wich chart i could use.

Hi,

One thing that seems to be often used is a donut like display like a car's engine load.

You could use the donut chart example to get started.

Hope it helps
