# for testing purposes, but it serves quite well to demonstrate |

# the code and classes within, so we are simply borrowing that  |

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

<li>File Menu

 | 
						|
    <ul>
 | 
						|
    <li>Page Setup
 | 
						|
 | 
						|
        <p>This allows you to set up how the plot will be printed. This
 | 
						|
        is built into the library itself.
 | 
						|
       
 | 
						|
    <li>Print Preview
 | 
						|
 | 
						|
        <p>As you might expect, this allows you to preview how the plot
 | 
						|
        will look when printed, in light of the page setup you may
 | 
						|
        have selected above.
 | 
						|

						|
    <li>Print
 | 
						|
    
 |

        <p>Surprise! It prints the current plot to your printer! :-)

 | 
						|
    <li>Save Plot
 | 
						|
    
 | 
						|
        <p>That's right, the library even provides you with the means
 | 
						|
        to export the plotted data out to a graphics file. Several
 | 
						|
        formats are allowed for, basically any image class that
 | 
						|
        supports saving.

    <li>Enable Zoom
 |

 | 
						|
        <p>If Zoom is enabled, you can rubber-band select an area of the
 | 
						|
        plot to examine it in detail using the left mouse button. Right
 | 
						|
        mouse button zooms back out. This is automatically supported
 | 
						|
        by the library, all you have to do is turn it on.

    <li>Enable Grid
 |

 |

        <p>Plots can have different styles of grids, and and these grids can

        be turned on or off as needed.

 |

        <p>Plot can have legends or not, the contents which are definable

        by you.
