     The oscilloscope application demonstrates how to use the Qt Charts QML API to implement an
     application with strict performance requirements. The application uses generated data with
-    configurable characteristics to mimic a simple oscilloscope user interface. To find out the
-    actual screen refresh performance of the application, you can set QML_SHOW_FRAMERATE = 1 to
-    your run environment settings to get the framerate shown in the application output console.
-    To do so go to Projects - Run - Run environment in Qt Creator and select Add. Then you can
-    experiment with the different configurable options of the example application to find the
-    configuration that gives you the best performance in your environment.
