**  This is the example code for QCustomPlot.                                                              **
**                                                                                                         **
**  It demonstrates basic and some advanced capabilities of the widget. The interesting code is inside     **
**  the "setup(...)Demo" functions of MainWindow.                                                          **
**                                                                                                         **
**  In order to see a demo in action, call the respective "setup(...)Demo" function inside the             **
**  MainWindow constructor. Alternatively you may call setupDemo(i) where i is the index of the demo       **
**  you want (for those, see MainWindow constructor comments). All other functions here are merely a       **
**  way to easily create screenshots of all demos for the website. I.e. a timer is set to successively     **
**  setup all the demos and make a screenshot of the window area and save it in the ./screenshots          **
**  directory.                                                                                             **
**                                                                                                         **
