Qwt ploting financial data

CONFIG += qwt

That's enough, when you did a "make install" before.

read in the install file about a QWT_DLL that I should include somewhere, ...

QWT_DLL is mentioned in the section about what to do, when not working with qmake. Instead this is what you need to do:

• configure qmake to find qwt.prf ( C:\Qwt-6.1-rc2\features ) : https://qt-project.org/doc/qt-4.8/qm...ation-features
• extend your PATH so that qwt libraries can be found
