-------------------------------------------------------------
+- groupplots + extra braces or \foreach are incompatible.
+
+- clickable and Windows Acrobat Reader 9 has been reported to fail
+
+- /pgfplots/samples at and /tikz/samples at work on the same axe. Tantau says that this key support \foreach statement and thus the dotes notation. Howerver, when I want to use two or more different dots notation within pgfplots, latex crashes !
+Here is an example which clarify this issue :
+\addplot+[mark=none,variable={\t}, samples at = {\foreach \x in {0,10,...,180,200,...340} {\x, }360}] ({sin(t*2)}, {cos(t)});
+
+- potential incompatibility: clickable and external. The clickable lib writes
+ into pgfplots.djs which might cause multithreaded problems.
+
+- groupplots: mixing 2d/3d in one groupplot doesn't reset 'zmin,zmax' ?
+
+
+- 'clip=false' does not disable marker clipping!
+
+- mark position clipping may fail: see
+ \begin{tikzpicture}
+ \begin{axis}
+ \addplot3[surf,shader=faceted,
+ scatter,mark=*,
+ samples=10,domain=0:1]
+ {x^2*y};
+ \end{axis}
+\end{tikzpicture}
+ in the manual (shader docs)
+
+- multiple ordinates: grid lines are drawn on top of function plots; that's bad.
+Check:
+ I think you have to change the process line previousely invoked, and make the axes generation at the end :
+1. generating adequate grid --> 2. plotting functions --> 3. creating axes, tick nodes...
+You can take a minute look at figure 1 @ "The \addplot Command: Coordinate Input" section 4.2 p 19.
+and you can remark that colour filling overlaps x- and y-axis ! So I suggest that you use "excute at end picture=<axis generation code>" tikz option or similar to avoid this issue.
+
+- patch plots: type rectangle & shader=interp & mesh input=patches doesn't work
+ correctly as it seems.
+
+- 3D axes: it is difficult to get an 1:1 correspondence to tikz.
+
+- 3D axes: providing three unit vectors is not sufficient, one also needs to set
+ 'view={}{}'. That should be done automatically.
+
+- 3D axes: Providing three unit vectors manually yields incorrect axis
+ initialisation.
+
+- 3D axis: provide support for manual axis configuration,
+ - depth (n vector),
+ - foreground/background,
+ - tick label axes,
+ - ...
+
+- Patch plots: directly transform cdata. Should simplify interpolation during
+ refine/triangulation etc. and shouldn't make a difference otherwise.

+
+- plot graphics: \ref legend doesn't work properly
+
+- french babel and colorbars are not fully compatible. The problem is that

+ which might lead to problems.
+

+
++ plot graphics braucht
+ every legend image post/.append style={sharp plot}
+
+- markers should not be drawn on top of everything else. Always restore the

+
+- \ref and detached legends/colorbars do NOT work with external library and
+ convert with system call.
+ -> provide special handling!
+
++ providing 'thick' to linespecifications causes problems during the survey
+ phase: \pgfmathsetlength{} will use the FPU.

+- shader=interp,z buffer=sort ---> should use 'shader=faceted interp,faceted
+ color=none,z buffer=sort' instead!
+
+- mesh/patch plots:
+ - jump thing + z buffer=sort probably doesn't work
+
+- ternary axes: the 'marker clipping' doesn't work (naturally)
+
++ shader=interp: I stumbled over a data set for which gv,xpdf,kpdf and acrobat
+ bail out with an error. (data file in feuersaenger's thesis)
+ ---> That's y varies! For x varies, it works!

+- colormap serialization has N^2 runtime.
+
+- `1.23456e4;' in a log plot resulted in hard-to-read error messages. Improve
+ sanity checking here.

+ \begin{tikzpicture}
+ \begin{semilogyaxis}[
+ ybar stacked,
+ ymin=1e1, ymax=1e6,
+ ]
+ \addplot coordinates { (1,100) (2,100) };

+ \end{semilogyaxis}
+ \end{tikzpicture}
+
+- the title style for 'footnotesize' is not as I want it to: it doesn't respect
+ the depth below the baseline. Or does it need a \strut?
+
++ the 'enlarge x limits={abs=3}' key doesn't work: it increases the lower
+ limits, but it doesn't draw any tick labels (neither major nor minor)
+
+
++ portability of externalized \label commands: define \tikzifinpicture which
+ should be part of the external separate package (in which case it is always
+ false).
+
+- avoid dimension too large errors which occur due to a data range restrictions.
+ Example:
+ data range = 0:6000
+ view range = 0:1
+ -> results in error.
+ But that's easy to detect! Just compute the point coordinate in float (after
+ the scaling is complete). Then, install a filter somewhere. perhaps an "a
+ posteriori" filter in the pointxyz command?
+
+- the 'colorbar sampled line' and 'colorbar left' styles are incompatible:
+ there are no tick lines.
+
+X bug in linux printer drivers: colorbar shadings are not interpolated
+ correctly, the interp shadings work (also the colormap sampled style).

+
+- the autodetection of the '\\' list format is buggy: it should return true if

+
+- improve access to `create on use' things in \addplot table.
+ Ideas:
+ - check if a `create on use' statement for table/[xyz] exists, if so: load the complete
+ table.
+ - allow a simplified syntax like 'y=create col/linear regression{<args>}'.
+ This should be possible; just introduce a temporary name (or column

+ - Maybe a more straight forward way for legend to implement something like
+ shown in the graph. (see his mail .tex)
+ -> plot marks only at specific points.
+ thus, the legend image should contain both lines and marks, but there
+ are effectively two \addplot commands.
+ - As a physicist, I often have the problem to fit curves. A job gnuplot can do

+
+- idea: 'mesh/ordering=auto'. Just check for 'x varies' and 'y varies'! The two
+ first points inside of a scanline are enough.
+
+- it is possible to output contour data into files with gnuplot (and with
+ matlab):
+ unset surface
+ set contour
+ # set cntrparam ...
+ set table 'P.dat'
+ splot [x=0:1] [y=0:1] x*y;
+ unset table
+ # contour info now in filename
+- contourf: I guess filled contour plots could be possible if always two
+ adjacent color levels are combined into a single path which is then filled
+ with the simplified even/odd rule (not the winding fill rule). With the
+ underlying smoothness assumption C^0, there can't be any level between two
+ adjacent ones, and there can't be self-intersections.
+- it would be very interesting to allow more flexible handling of empty lines in
+ input data, especially files.
+ For example 'empty lines=auto|scanline|nan|jump' -> allows to use "interrupted
+ line plots" -> contour!
+ Implementation ideas:
+ - in table: check the mode. If "nan|jump" and "previous coord was no jump":
+ insert a "nan nan nan.... nan" line into the table.
+ - in plot coords: same, but it is simpler.
+ - perhaps I can implement the stuff like \pgfplotsscanlinecomplete: it
+ should stream a coordinate if it fails. The coordinate will use
+ x=inf,y=inf,z=inf and all remaining fields are kept from the last valid
+ coordinate. Should not hurt...
+ - the choice "auto" could be used as follows:
+ 3d plot ---> use "scanline"
+ 2d plot ---> use "nan"
+
+- interesting: add "path after line segment". Idea: allow nodes on the path
+ \tikz \draw (0,0) -- (3,1)
+ node[pos=0]{0} node[pos=0.5]{1/2} node[pos=0.9]{9/10};
+ -> perhaps such a feature can be the low level implementation for contour
+ labels.
+ Problems: how should the positions be determined automatically? Overlap should
+ be reduced somehow.
+ furthermore, a contour uses more than one path...
+
+
+
++ colorbar styles:
+ - colorbar flat
+ - colorbar faceted
+ -> use \addplot3[surf] to draw a colorbar
+ - colorbar scatter
+ -> use \addplot3[scatter] to draw a colorbar
+ -> requires to set samples, and to use plot expression. Should be enough...
+
+- implement simplified constructions to access DIFFERENCE coordinates.
+ For example, \draw ellipse needs x radius and y radius.
+
+
++ allow to anchor an axis at any labeled node inside of it (like for a matrix)
+
+- it might be interesting to fill the area between two paths. Perhaps there is
+ such a feature in pgf; or perhaps I can generalize the \closedcycle
+ implementation written for stacked plots.
+
+- provide a \numplotsperplothandler or something like that. This would improve
+ things for bar plots!
+
+- the 'table/y index' should be changed. It should be min(numcols,1) instead of 1.
+
+- table package & axes should improve their communication.
+ Namely:
+ - communicate table names.
+ - communicate xmode/ymode
+ - communicate log basis [xy]
+
++ provide col sep=&
+
+- provide and document access to (sanitized?) mesh/rows and mesh/cols fields
+ during the survey phase. This might allow 2d key filters

+ - newempty()
+ - clone()
+ - unscope()
+ - startPushBackSequence()
+ - stopPushBackSequence()
+ -> this could allow to use arrays for fast algorithms. At least it would make
+ things easier to read.
+ Problem as always: the 'unscope()' operation.
+ Currently, I have two different structures: the applists which have fast
+ construction properties and the standard lists which implement the rest.
+ Can I combine both? Yes, by means of the incremental construction pattern:
+ \startPushBackSequence
+ \push_back
+ \push_back
+ \push_back
+ \stopPushBackSequence
+ -> inside of the construction, only \push_back is allowed and the structure is
+ in "locked state" (low level: applist repr)
+ -> Idea: the creation is fast, afterwards, it has flexibility.
