      @StudyQt1 said in Plotting chart using lots of data:

      Is there a generic way to decide?

      Use a profiler. If you're using GCC you can use https://www.thegeekstuff.com/2012/08/gprof-tutorial/
      Easier way which is often enough is simply to put debug output at the beginning and end of your methods/functions with timestamps and then check the output of your application while it is running.

      @J-Hilk
      Ok that's enough I think.

      One more question what will happen to scrolleft().

      If I keep on incrementing these, will there be any increase in runtime memory or processor load?

      Hello! If I understood correctly, and you want to use the same chart view to represent the data in different forms like bars or line, I don't see any reason why not.
      If you take a look at https://doc.qt.io/qt-5/qtcharts-lineandbar-example.html, you can find an example of showing both a bar and line charts in the same chart, at the same time. From there, you can modify to show just one at a time, so in your case switching between the series when the menu action is triggered.

      If your files all have the same structure (separator, data etc.), yes, you should actually.
