How do I display more than 600,000 points on the chart?
I would like to display the data(about 610,000 point) for one week stored every second using qtchart.
It is too slow to test.
The basic functions of the chart should be implemented as well.
(Zoom in, zoom out, multi series ...)
How can I implement it?
You could try an alternative to QChart - QCuslomPlot. It has all of the features mentioned implemented.
QtCharts is ugly and too slow, and have memory leaks. IMHO, it is better to use Qwt.
@Eligijus Thanks.. i will try...
