Hi @Reuven, and welcome to the Qt Dev Net! Do you have a preference between Qt Quick and Qt Widgets? For plotting in Qt Quick, see the Stocqt example. For plotting in Qt Widgets, see the Qwt framework (note: This is a 3rd-party library that you must download separately) For browsing files in Qt Quick, see FileDialog (and an example) For browsing files in Qt Widgets, see QFileDialog
