Module wx.lib.plot
This is a simple light weight plotting module that can be used with
Boa or easily integrated into your own wxPython application. The
emphasis is on small size and fast plotting for large data sets. It
has a reasonable number of features to do line and scatter graphs
easily as well as simple bar graphs. It is not as sophisticated or
as powerful as SciPy Plt or Chaco. Both of these are great packages
but consume huge amounts of computer resources for simple plots.
They can be found at http://scipy.com
This file contains two parts; first the re-usable library stuff, then,
after a "if __name__=='__main__'" test, a simple frame and a few default
plots for examples and testing.
Based on wxPlotCanvas

- Major Additions Gordon Williams Feb. 2003 (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 sec
Markers
Square - 0.22 sec
dot - 0.10
circle - 0.87
cross,plus - 0.28
triangle, triangle_down - 0.90
Thanks to Chris Barker for getting this version working on Linux.
- Zooming controls with mouse (when enabled):
- Left mouse drag - Zoom box.
Left mouse double click - reset zoom.
Right mouse click - zoom out centred on click location.
