Qt OpenGL Widget as a view port for qcustomPlot

@SGaist
I need to plot real-time signal and I want to use openGL because this plot will be run on raspberry pi "as known the pi CPU very very slow to plot real-time data"

Hi, I moved the topic to "Mobile and Embedded" as it is about doing embedded.

In that case you should rather look for a solution that can be power by OpenGL e.g. QtCharts

@SGaist
I think, I have to buy Qt licence to install QtCharts, isn't it?

It will be available to both Commercial and GPLv3 since 5.6. See this article. So if your application is GPLv3 then your good to go.

I am using Qt 5.6 Creator but

QT += charts

gives me an error:

Project ERROR: Unknown module(s) in QT: charts

I have used qwt. It is coolest open source lib for chart, I would strongly recommend. Check it out if it meets your requirement.

Because it's not part of Qt 5.6, you have to compile it by hand.

The documentation here mentions that I can use Package Manager in Maintenance Tool. But for Qt Creator there is no option there to install add-ons. CAn you suggest me something?

Again: currently it's not yet part of Qt's OpenSource offering so you have to clone it using git and built it by hand. The repository is here
