   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.                                        |

  31 This demo illustrates the features of the new PyPlot modules, found
  32 in wx.lib.plot.py. All methods and functions are documented clearly
  33 therein; only the overview is included here.
  34
  35 <p>
  36 PyPlot is an improvement over wxPlotCanvas, which is now deprecated.
  37 If you are using wxPlotCanvas now, please make plans to migrate in
  38 anticipation of the time that wxPlotCanvas disappears completely.
  39
  40 <p>
  41 The demo illustrates four different plot styles (with appropriate
  42 variations on fonts, etc, to show how flexible it is) as well as
  43 provides you with a means to tinker with all the features that
  44 come with the class itself.
  45
  46 <p><ul>
  47 <li>File Menu
  48
  49     <ul>
  50     <li>Page Setup
  51
  52         <p>This allows you to set up how the plot will be printed. This
  53         is built into the library itself.
  54
  55     <li>Print Preview
  56
  57         <p>As you might expect, this allows you to preview how the plot
  58         will look when printed, in light of the page setup you may
  59         have selected above.
  60
  61     <li>Print
  62
  63         <p>Surprise! It prints the current plot to your printer! :-)
  64
  65     <li>Save Plot
  66
  67         <p>That's right, the library even provides you with the means
  68         to export the plotted data out to a graphics file. Several
  69         formats are allowed for, basically any image class that
  70         supports saving.
  71     </ul>
  72
  73 <li>Plot Menu
  74
  75     <ul>
  76     <li>Plot 1 ... Plot 5
  77
  78         <p>Different data with different plot formats, including one empty
  79         plot.
  80
  81     <li>Enable Zoom
  82
  83         <p>If Zoom is enabled, you can rubber-band select an area of the
  84         plot to examine it in detail using the left mouse button. Right
  85         mouse button zooms back out. This is automatically supported
  86         by the library, all you have to do is turn it on.
  87
  88     <li>Enable Grid
  89
  90         <p>Plots can have different styles of grids, and and these grids can
  91         be turned on or off as needed.
  92
  93     <li>Enable Legend
  94
  95         <p>Plot can have legends or not, the contents which are definable
  96         by you.
  97     </ul>
