I’ve had a good experience adding KPlotWidget into my application for simple line plots. It’s simple and easily to modify if required.

It is embedded device, there are no any HTML, JS and other stuff. сб, 23 мар. 2019 г. в 00:03, Alexander Nassian <nass...@bitshift-dynamics.com<mailto:nass...@bitshift-dynamics.com>>: Did you have a look on QChart.js? Otherwise you could just wrap Qwt in a QQuickPaintedItem to integrate that single QWidget component in the otherwise QtQuick UI.

QtCharts in not an option. :) I thought that maybe I could use the OpenGL widget in QtWidgets app to render a curves there (e.g. with Qwt). But in this case I need in the working OpenGL on X11 (which is not exists). 22.03.2019 21:29, Alexander Nassian пишет: Then you should go with EGL and QtQuick if you want to utilize the GPU. X11 is mostly a horrible idea on embedded systems (and in general too if you would ask me). Widgets are drawn by the CPU as far as I know.
