   8 # wx.lib.plot.py came with its own excellent demo built in,     |
   9 # for testing purposes, but it serves quite well to demonstrate |
  10 # the code and classes within, so we are simply borrowing that  |
  11 # code for the demo. Please load up wx.lib.plot.py for a review |
  12 # of the code itself. The demo/test is at the bottom of         |
  13 # the file, as expected.                                        |

  45 This demo illustrates the features of the new PyPlot modules, found
  46 in wx.lib.plot.py. All methods and functions are documented clearly
  47 therein; only the overview is included here.
  48
  49 <p>
  50 PyPlot is an improvement over wxPlotCanvas, which is now deprecated.
  51 If you are using wxPlotCanvas now, please make plans to migrate in
  52 anticipation of the time that wxPlotCanvas disappears completely.
  53
  54 <p>
  55 The demo illustrates four different plot styles (with appropriate
  56 variations on fonts, etc, to show how flexible it is) as well as
  57 provides you with a means to tinker with all the features that
  58 come with the class itself.
  59
  60 <p><ul>
  61 <li>File Menu
  62
  63     <ul>
  64     <li>Page Setup
  65
  66         <p>This allows you to set up how the plot will be printed. This
  67         is built into the library itself.
  68
  69     <li>Print Preview
  70
  71         <p>As you might expect, this allows you to preview how the plot
  72         will look when printed, in light of the page setup you may
  73         have selected above.
  74
  75     <li>Print
  76
  77         <p>Surprise! It prints the current plot to your printer! :-)
  78
  79     <li>Save Plot
  80
  81         <p>That's right, the library even provides you with the means
  82         to export the plotted data out to a graphics file. Several
  83         formats are allowed for, basically any image class that
  84         supports saving.
  85     </ul>
  86
  87 <li>Plot Menu
  88
  89     <ul>
  90     <li>Plot 1 ... Plot 5
  91
  92         <p>Different data with different plot formats, including one empty
  93         plot.
  94
  95     <li>Enable Zoom
  96
  97         <p>If Zoom is enabled, you can rubber-band select an area of the
  98         plot to examine it in detail using the left mouse button. Right
  99         mouse button zooms back out. This is automatically supported
 100         by the library, all you have to do is turn it on.
 101
 102     <li>Enable Grid
 103
 104         <p>Plots can have different styles of grids, and and these grids can
 105         be turned on or off as needed.
 106
 107     <li>Enable Legend
 108
 109         <p>Plot can have legends or not, the contents which are definable
 110         by you.
