Biggles

===================

* Biggles now requires the Numeric Python module, and is no longer
a pure Python module.

* Added support for contour plots with new Contours() component.

* HammerAitoffPlot(): new & improved geodesic algorithm; added
support for rotated coordinates.

* Added FillAbove(), FillBelow() components. Fill*() objects now
work with PlotKey().

* More robust interactive session detection. The config.ini option
"[screen] guess_interactive" has been renamed "persistent".
Removed interactive() function.

* Better tick guesses for log axes.

* Bug fixes: apparent data scaling by FramedArray when aspect_ratio
is set; several related to calculating limits.

===================

* Breaks old Table cell{spacing,padding} values; multipying them by
100 should work in most cases.

* Renamed Label{Data,Plot} -> {Data,Plot}Label, LineSlope -> Slope,
and ErrorEllipses -> Ellipses. The old names still work but are
deprecated.

* {Line,Symbol}Key have been superceded by PlotKey and are now
deprecated.

* New plot type: CustomFramedPlot(). Similar to FramedPlot(), but
allows finer control over the frame style.

* New plot type: HammerAitoffPlot(). An equal-area projection of the
sphere, Hammer-Aitoff plots are commonly used in astrophysics.

* New FramedArray options: .uniform_limits & .cellspacing.

* New components: Circle(s), Ellipse, Geodesic, Point, PlotInset,
and PlotLine.

* You can now specify a minimum fontsize with "fontsize_min" in
config.ini.

* Various speed improvements, bug fixes, and infrastructure work.

===================

* Reorganized config.ini file.

* The readcolumn() function can be configured to return Numeric arrays.

* Added interactive() function to let users control X window behavior.

* Fixed a couple of axis bugs triggered by very large limits.

===================

* Added distutils setup.py file. [contributed by Berthold H�llmann]

* Added FramedArray container for grouping similar plots.

* Added SymmetricErrorBars[XY] helper functions.

* You can now say "t[i,j]=x" instead of "t.set(i,j,x)" for Table
objects.

* Broke readcolumn() so users can pass in their own string -> number
conversion functions. Also, readcolumn now ignores blank lines and
those starting with a comment character.

* When used interactively, biggles now reuses the same X window
insteading of creating a new window each time .show() is called.

* Fixed stupid printing bug.

===================

* LineKey, SymbolKey, and Inset now take plot coordinates instead of
data coordinates. Plot coordinates run from 0 -> 1 for each axis.
Sorry about the breakage.

* Inset coordinates now specify the frame location, not the bounding
box. More breakage.

* Replaced Label with LabelData & LabelPlot. LabelData works the same
as Label, and LabelPlot takes plot coordinates instead of data
coordinates.

* Added LineSlope, Line[XY] components.

* Added readcolumn() function. Returns a list of column values from
a flat ASCII file.

* More namespace cleanup.

===================

* Fixed a couple of layout bugs. Handling of large tables and
elongated plots is greatly improved. [thanks to Jamie Mazer]

* .save_as_{eps,img}() now recognize the filename "-" as stdout.

* Better log ticks.

* Namespace cleanup.
