/************************************************************************************************************
** **
** 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. **
