|
# o 2.5 compatability update.
|

|
|
# o Renamed to plot.py in the wx.lib directory.
|
||
|
|
# o Reworked test frame to work with wx demo framework. This saves a bit
|
||
|
|
# of tedious cut and paste, and the test app is excellent.

# Oct 6, 2004 Gordon Williams (g_will@cyberus.ca)
|
||
|
|
# - Added bar graph demo

|
||
|
|
# - Added Cursor Line Tracking and User Point Labels.
|
||
|
|
# - Demo for Cursor Line Tracking and Point Labels.
|
||
|
|
# - Size of plot preview frame adjusted to show page better.
|
||
|
|
# - Added helper functions PositionUserToScreen and PositionScreenToUser in PlotCanvas.
|
||
|
|
# - Added functions GetClosestPoints (all curves) and GetClosestPoint (only closest curve)
|
||
|
|
# can be in either user coords or screen coords.

|

|
|
# - 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(<number>, SetYSpec(<number>) -- work like 'min', but with
|
||
|
|
# <number> tick marks)
|
||
|
|
# - Added support for background and foreground colours (enabled via
|
||
|
|
# SetBackgroundColour/SetForegroundColour on a PlotCanvas instance)
|
||
|
|
# - Changed PlotCanvas printing initialization from occuring 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

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.
|
||
|

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.
