Unsolved QChart very slow
-
Hi everyone.
I am a beginner in Qt.
I have a problem with charts.
I took the example as a reference: Zoom Line Example (https://doc.qt.io/qt-5/qtcharts-zoomlinechart-example.html).I noticed, however, that when I use a series with a number of points greater than 10000, the graph slows down a lot by blocking the GUI too.
Is there a way to run the chart in another thread?
Can anyone write me a code example?
Thank you all for your availability.Greetings.

Don't show all points at all time. If you zoom-out, reduce the number of visible points by e.g. showing every second point only.
