Hi. There are ways to do a chart. For example, QCustom Plot, Qt Charts and there is qwt.
Which is the best way for doing it?
What is the most important difference between them?

Thank you for answers

Hi
Well "best" is a very vague term but we can talk about the 3 mentioned

QCustom Plot

very easy to use. just 2 files to add to project. API is easy to understand.
free for open source
interface is easy to understand

Docs not the best
Not a native Qt solution

Qt Charts

Many features
Ready for use if installed. ( native to Qt)
Can be used now for open source as far as i know

Can be very hard to customize. Even with the good docs.

Qwt

Has Designer plugin so graphs can be used Design time
Pretty fast

Often you need to compile and integrate yourself.
Not so beginner-friendly

Do note that the above points are just what I think. Others might have another view on say QChart.

That said, QCustom Plot is by far easier to use. So if you are in doubt then I would
go for QCustom Plot.
