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)
19 - make graph.style.symbol.diamond a graph.style.symbol instance (to be discussed)
21 - use csv module (new in 2.3)
22 - Check for "inf" and "nan" in datafiles.
23 (When plotted, the graph does not complain, but the output will be broken;
24 this depends on the plattform and is not only an issue within the graph system)
26 - add styles using curves instead of lines
27 - histogram doesn't stroke lines to the baseline for steps=0 when two subsequent values are equal
29 - contructor should only take a texrunner keyword argument
32 - stroking of patterns does not work in PDF

34 time -> rewrite this code
35 - style and color module:
36 - support modification of existing styles via __call__
38 - height -> getheight, ...
40 - support single-character mode
42 - palette: are the min and max parameters really needed or shouldn't we just assume
43 that param lies within the range [0,1]. Note that when using a predefined palette (which
44 is the common use case), they will be 0 and 1, anyway.
46 - move helper path routines to some more generic place for paths?
48 - clearly distingish between readers and writers. dvifile, epsfile, etc. might
49 be renamed to dvireader, epsreader ...
50 - support gsave and grestore in some way to make context handling easier?
52 - support colorspace argument (like c.writeEPSfile("bla", colorspace="cmyk"))
57 - more details in path constructor: allowed pathels, first pathel...
62 Changeable attributes should be explained at a central place.
64 - linealign and circlealign
65 - need to be redone anyway
67 styles: document what data name the styles accept (require). Try also to be more
68 userfriendly and not to describe immediately the internals of the implementation:
69 (see e.g. class.style.symbol)
70 - include the deformer docu somewhere in path
73 - describe creation and modification (inplace and ``modify by new'') of
79 - add encoding; check whether encoding=ascii works well for the common existing cases
80 - we need output-specific map files (see Palatino example
81 http://sourceforge.net/mailarchive/message.php?msg_id=14863643)

97 - default style instantiation bug (reported by Gregory Novak)
99 - automatic subaxis tuple creation removed in barpos (create tuples

655 - rounding towards zero bugfix in autolinpart
656 - log axis range rating bugfix
658 - addarg bugs (#738724)
660 - fix mixing up of height and width in scale calculation
661 - and various other fixer here and there
665 - fix bug in dvi rule code where width was height
666 - fix preamble attribute checking bug
667 - fix texmessage.load pattern search instead of pattern match bug
668 - renamed vbox to parbox (was done in 0.3 partially only)
670 - allow for tuples in arguments of the data class
671 - convenience: exchanged order of named parameters in data.data
673 - convenience: allow for part=None in _axis (base of linaxis and logaxis)
675 - added a latex example (requested)
676 - added a attributechange example (requested)
677 - added back the integral example (requested; prior PyX 0.3 it was part of the user manual)
678 - small change in vector example (allow for the access to the texrunner)
679 - examples included in source distribution
681 - correct arrow template calculation for very short paths
685 - new easy to use example generation (will hopefully lead to nice examples)
687 - new module for handling of convex polygons (taken out of the graph module)
689 - new module containing a collection of helper functions (taken out of the graph module)
690 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
692 - new module: a new and preferable integration of TeX/LaTeX
694 - strip glyphs from pfa/pfb-fonts
695 - there is a C implementation taken from pdftex
696 - fallback solution via an external program (pfb2pfa)
698 - (partial) C binding to libkpathsea
699 - fallback solution via an external program (kpsewhich)
701 - removed some code duplication (various axis painters)
702 - use text module instead of the obsolete tex module
703 - allow for tailing zeros of automatic generated labels
704 - allow for missing data in bar graphs -> skipmissing parameter
705 - remove the support for variables given as keyword arguments in data constructor
706 - use context instead of extern for extern variables and functions
707 - graph keys; titles in data/function/etc.
709 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
710 - all length classes have now by default a quantifier 1 (instead of 0), such that,
711 for instance, 5*unit.t_cm() == unit.t_cm(5)
712 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
713 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
715 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
716 for internal purposes.
717 - the bbox constructor now accepts user lengths in the constructor.
718 - new methods height, width, top, bottom, left, right
719 - ll & ur ???, what about ul and lr -> ugly!
720 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
721 - output HiResBoundingBox
722 - never reduce bbox upon output
724 - new constructor signature, more in line with rest of PyX:
725 epsfile(x, y, filename, **additional_args)
727 - removed additional column support in addcolumn; removed _addcolumn
728 - line reduction for datafile like the every parameter in gnuplot
730 - new way of PS prolog generation that writes only necessary parts
731 - added support for patterns
732 - canvas.insert() now supports arguments
733 - bbox of canvas can be specified in writetofile command explicitely
734 - writetofile does not return self anymore
735 - arrow template now uses intersection with circle to get size right
736 (as per a suggestion by Michael Schindler)
739 - changed the handling of extern functions and all variables
741 - gradient renamed to palette
743 - problem with sizefile on windows (tex module)
744 - allow for strings in graphxy's width and height; allow for width only (graph module)
745 - disable rating for labelattrs equals None (graph module)
746 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
747 - traverse when adding functions as arguments of operators (mathtree module)
748 - allow for extern functions in addcolumn (data module)
749 - just one common place for the version number
750 - fix incorrect exception name MathError (path module)
751 - prevent double return of intersections for closed sub paths
756 - allow division of length by numbers
758 - new transformation: slant
759 - renamed all trafo methods to use the participle (i.e translate->translated)
760 - the name of all trafo subclasses are verbs (i.e. translation->translate)
762 - mark class renamed to symbol
763 - (text-)box distance measurement
764 - moved axis partitioning to axis and axis painter
765 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
767 - baraxis, baraxispainter, and bar style
769 - previously named datafile module
770 - class "_datafile" renamed to class "data"
771 - class sectionfile added
774 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
777 - deferred to Version 0.3
778 - running TeX "on the fly" is basically implemented
780 - transformation bug (#624068, trafo module)
781 - canvas transformations (canvas module???)
782 - textbox alignment (graph module)
783 - return linewidth upon calculation with linewidths (unit module)
784 - allow column number variables with several digits
786 - british and american spellings (color module, graph module)
787 - small logo modifications
