Refactored PolyBars and PolyHistogram to PolyBarsBase class
Replaced SaveBrush et. al., with more generic TempStyle combination Context Manager and Decorator.

updated xSpec and ySpec to accept a list or tuple of (min, max) values.

2015-08-20 - Douglas Thor (doug.thor@gmail.com) (PR #26)

Implemented a drawstyle option to PolyLine that mimics matplotlib's Line2dD.drawstyle option.
Added significant customization options to PlotCanvas
- Gridlines, Axes, Centerline, diagonal, and ticks can now have their Pen (color, width, and linestyle) set independently.
- Ticks, Axes, and AxesValues can now be turned on/off for each side.
Added properties to replace getters/setters.
All getters and setters now have deprecation warnings
Fixed python3 FutureWarning for instances of 'x == None' (replaced with 'x is None')
Documentation updates

Added context manager and decorator that gets and resets the pen before and after a function call
updated demo for new features
Most items are now allow custom pens (color, width, linestyle)

2009-06-22 - Florian Hoech (florian.hoech@gmx.de)

Fixed exception when drawing empty plots on Mac OS X
Fixed exception when trying to draw point labels on Mac OS X (Mac OS X point label drawing code is still slow and only supports wx.COPY)
Moved label positions away from axis lines a bit
Added PolySpline class and modified demo 1 and 2 to use it
Added center and diagonal lines option (Set/GetEnableCenterLines, Set/GetEnableDiagonals)
Added anti-aliasing option with optional high-resolution mode (Set/GetEnableAntiAliasing, Set/GetEnableHiRes) and demo
Added option to specify exact number of tick marks to use for each axis (SetXSpec(, SetYSpec() -- work like 'min', but with tick marks)
Added support for background and foreground colours (enabled via SetBackgroundColour/SetForegroundColour on a PlotCanvas instance)
Changed PlotCanvas printing initialization from occurring in init to occur on access. This will postpone any IPP and / or CUPS warnings which appear on stderr on some Linux systems until printing functionality is actually used.

Imported modules given leading underscore to name.
Added Cursor Line Tracking and User Point Labels.
Demo for Cursor Line Tracking and Point Labels.

2004-08-06 - Gordon Williams (g_will@cyberus.ca)

Added bar graph demo
Modified line end shape from round to square.
Removed FloatDCWrapper for conversion to ints and ints in arguments

2003-12-15 - Jeff Grimmett (grimmtooth@softhome.net)

2.5 compatibility update.

Reworked test frame to work with wx demo framework. This saves a bit of tedious cut and paste, and the test app is excellent.

2003-02-?? - Gordon Williams (g_will@cyberus.ca)

More style options
Zooming using mouse "rubber band"
Scroll left, right
Grid(graticule)
Printing, preview, and page set up (margins)
Axis and title labels
Cursor xy axis values
Doc strings and lots of comments
Optimizations for large number of points
Legends

Did a lot of work here to speed markers up. Only a factor of 4 improvement though. Lines are much faster than markers, especially filled markers. Stay away from circles and triangles unless you only have a few thousand points.

+--------------------------------------------+
| Times for 25,000 points                    |
+============================================+
| Line                             | 0.078 s |
+----------------------------------+---------+
| Markers: Square                  | 0.22 s  |
+----------------------------------+---------+
| Markers: dot                     | 0.10    |
+----------------------------------+---------+
| Markers: circle                  | 0.87    |
+----------------------------------+---------+
| Markers: cross, plus             | 0.28    |
+----------------------------------+---------+
| Markers: triangle, triangle_down | 0.90    |

Thanks to Chris Barker for getting this version working on Linux.
