	15	# for testing purposes, but it serves quite well to demonstrate \|
	16	# the code and classes within, so we are simply borrowing that \|
	17	# code for the demo. Please load up wx.lib.plot.py for a review \|
	18	# of the code itself. The demo/test is at the bottom of \|
	19	# the file, as expected. \|

	63	<center><h2>PyPlot</h2></center>
	64
	65	This demo illustrates the features of the new PyPlot modules, found
	66	in wx.lib.plot.py. All methods and functions are documented clearly
	67	therein; only the overview is included here.
	68
	69	<p>
	70	PyPlot is an improvement over wxPlotCanvas, which is now deprecated.
	71	If you are using wxPlotCanvas now, please make plans to migrate in
	72	anticipation of the time that wxPlotCanvas disappears completely.
	73
	74	<p>
	75	The demo illustrates four different plot styles (with appropriate
	76	variations on fonts, etc, to show how flexible it is) as well as
	77	provides you with a means to tinker with all the features that
	78	come with the class itself.

	80	<p><ul>
	81	<li>File Menu
	82
	83	<ul>
	84	<li>Page Setup
	85
	86	<p>This allows you to set up how the plot will be printed. This
	87	is built into the library itself.
	88
	89	<li>Print Preview
	90
	91	<p>As you might expect, this allows you to preview how the plot
	92	will look when printed, in light of the page setup you may
	93	have selected above.
	94
	95	<li>Print
	96
	97	<p>Surprise! It prints the current plot to your printer! :-)
	98
	99	<li>Save Plot
	100
	101	<p>That's right, the library even provides you with the means
	102	to export the plotted data out to a graphics file. Several
	103	formats are allowed for, basically any image class that
	104	supports saving.

	112	<p>Different data with different plot formats, including one empty
	113	plot.
	114
	115	<li>Enable Zoom
	116
	117	<p>If Zoom is enabled, you can rubber-band select an area of the
	118	plot to examine it in detail using the left mouse button. Right
	119	mouse button zooms back out. This is automatically supported
	120	by the library, all you have to do is turn it on.
	121
	122	<li>Enable Grid
	123
	124	<p>Plots can have different styles of grids, and and these grids can
	125	be turned on or off as needed.
	126
	127	<li>Enable Legend
	128
	129	<p>Plot can have legends or not, the contents which are definable
	130	by you.
