6 - make dash length available
8 - SlantFont & Co support
9 - keep an eye on PEP 324 (popen 5): it could make the texrunner much easier
11 - common bboxes for different graphs
12 - 3d graphs, circular graphs
13 - axis painter labelattrs=None + automatic axis partitioning leads to no valid partitioning
14 - when all titles are None, a graph key currently raises an exception
15 - translatecanvas should be the default in graph.style.symbol
16 - graph.style and graph.data modules
17 - fix docu of gridattrs functionality of axis painters
18 (how can one, e.g. draw a grid at the ticks and not at the subticks)
20 - use csv module (new in 2.3)
21 - Check for "inf" and "nan" in datafiles.

26 - histogram doesn't stroke lines to the baseline for steps=0 when two subsequent values are equal
28 - contructor should only take a texrunner keyword argument

35 - support modification of existing styles via __call__
37 - height -> getheight, ...
39 - support single-character mode
41 - palette: are the min and max parameters really needed or shouldn't we just assume
42 that param lies within the range [0,1]. Note that when using a predefined palette (which
43 is the common use case), they will be 0 and 1, anyway.
45 - move helper path routines to some more generic place for paths?
47 - clearly distingish between readers and writers. dvifile, epsfile, etc. might
48 be renamed to dvireader, epsreader ...
49 - support gsave and grestore in some way to make context handling easier?
51 - support colorspace argument (like c.writeEPSfile("bla", colorspace="cmyk"))
56 - more details in path constructor: allowed pathels, first pathel...
61 Changeable attributes should be explained at a central place.
63 - linealign and circlealign
64 - need to be redone anyway
66 styles: document what data name the styles accept (require). Try also to be more
67 userfriendly and not to describe immediately the internals of the implementation:
68 (see e.g. class.style.symbol)
69 - include the deformer docu somewhere in path
72 - describe creation and modification (inplace and ``modify by new'') of
78 - add encoding; check whether encoding=ascii works well for the common existing cases

657 - fix mixing up of height and width in scale calculation
658 - and various other fixer here and there
662 - fix bug in dvi rule code where width was height
663 - fix preamble attribute checking bug
664 - fix texmessage.load pattern search instead of pattern match bug
665 - renamed vbox to parbox (was done in 0.3 partially only)
667 - allow for tuples in arguments of the data class
668 - convenience: exchanged order of named parameters in data.data
670 - convenience: allow for part=None in _axis (base of linaxis and logaxis)
672 - added a latex example (requested)
673 - added a attributechange example (requested)
674 - added back the integral example (requested; prior PyX 0.3 it was part of the user manual)
675 - small change in vector example (allow for the access to the texrunner)
676 - examples included in source distribution
678 - correct arrow template calculation for very short paths
682 - new easy to use example generation (will hopefully lead to nice examples)
684 - new module for handling of convex polygons (taken out of the graph module)
686 - new module containing a collection of helper functions (taken out of the graph module)
687 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
689 - new module: a new and preferable integration of TeX/LaTeX
691 - strip glyphs from pfa/pfb-fonts
692 - there is a C implementation taken from pdftex
693 - fallback solution via an external program (pfb2pfa)
695 - (partial) C binding to libkpathsea
696 - fallback solution via an external program (kpsewhich)
698 - removed some code duplication (various axis painters)
699 - use text module instead of the obsolete tex module
700 - allow for tailing zeros of automatic generated labels
701 - allow for missing data in bar graphs -> skipmissing parameter
702 - remove the support for variables given as keyword arguments in data constructor
703 - use context instead of extern for extern variables and functions
704 - graph keys; titles in data/function/etc.
706 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
707 - all length classes have now by default a quantifier 1 (instead of 0), such that,
708 for instance, 5*unit.t_cm() == unit.t_cm(5)
709 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
710 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
712 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
713 for internal purposes.
714 - the bbox constructor now accepts user lengths in the constructor.
715 - new methods height, width, top, bottom, left, right
716 - ll & ur ???, what about ul and lr -> ugly!
717 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
718 - output HiResBoundingBox
719 - never reduce bbox upon output
721 - new constructor signature, more in line with rest of PyX:
722 epsfile(x, y, filename, **additional_args)
724 - removed additional column support in addcolumn; removed _addcolumn
725 - line reduction for datafile like the every parameter in gnuplot
727 - new way of PS prolog generation that writes only necessary parts
728 - added support for patterns
729 - canvas.insert() now supports arguments
730 - bbox of canvas can be specified in writetofile command explicitely
731 - writetofile does not return self anymore
732 - arrow template now uses intersection with circle to get size right
733 (as per a suggestion by Michael Schindler)
736 - changed the handling of extern functions and all variables
738 - gradient renamed to palette
740 - problem with sizefile on windows (tex module)
741 - allow for strings in graphxy's width and height; allow for width only (graph module)
742 - disable rating for labelattrs equals None (graph module)
743 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
744 - traverse when adding functions as arguments of operators (mathtree module)
745 - allow for extern functions in addcolumn (data module)
746 - just one common place for the version number
747 - fix incorrect exception name MathError (path module)
748 - prevent double return of intersections for closed sub paths
753 - allow division of length by numbers
755 - new transformation: slant
756 - renamed all trafo methods to use the participle (i.e translate->translated)
757 - the name of all trafo subclasses are verbs (i.e. translation->translate)
759 - mark class renamed to symbol
760 - (text-)box distance measurement
761 - moved axis partitioning to axis and axis painter
762 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
764 - baraxis, baraxispainter, and bar style
766 - previously named datafile module
767 - class "_datafile" renamed to class "data"
768 - class sectionfile added
771 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
774 - deferred to Version 0.3
775 - running TeX "on the fly" is basically implemented
777 - transformation bug (#624068, trafo module)
778 - canvas transformations (canvas module???)
779 - textbox alignment (graph module)
780 - return linewidth upon calculation with linewidths (unit module)
781 - allow column number variables with several digits
783 - british and american spellings (color module, graph module)
784 - small logo modifications
