// Demonstrates how to create a basic empty plot window. This is probably
// not how you want to create a plot window. You will probably want one of the
// static or dynamic plot windows instead (which uses the PlotWindow structure)

	// The background will be entirely white. These are the default settings.
	// Since we haven't specified a title of the plot it will default to
	// "Figure - 1". Each subsequent untitled plot will increment.
	// "Figure - 2", "Figure - 3", etc.

	// This will just wait synchronously for all the plots to close *while*
	// event handling still occurs.
	//
	// Normal uses for this will be to open a plot with some information then
	// wait for the user to close it before continuing on with further
	// processing.
	//
	// since this is channel safe it can also be used with the dynamic plots
	// to display a plot and then wait for it to close while another channel
	// sends data to the plot to display.
