Changes since the previous build:

  • new feature: fill between plots (library fillbetween)
  • new feature: concatenate intersection segments (library fillbetween)
  • fixed bug: xelatex failed to run contour external
  • fixed incompatibility with \label and \usepackage{mcaption}
  • fixed bug: histograms produced wrong point meta
  • fixed bug: histograms reported the wrong 'plot name' and confused shifts of bar plots

Warning: The development version is not always stable. If the latest build causes problems, download and install an earlier build and wait for a bug fix.


Changes in earlier versions:


- new feature: asymmetric error bars
- new feature: activated math parser for axis limit arguments, arguments in axis cs, and domain argument in log plots
- new feature: stacked bar plots place their 'nodes near coords' correctly in the middle and print the increment (compat=1.9)
- new feature: stacked bar plots suppress empty increments (compat=1.9).
- new feature: 'scatter/position=relative|absolute' allow to position 'nodes near coords' absolutely.
   use-case: bar plots + nodes near coords which are at, say, y=0 rather than their y value
- new feature: integration of smooth shadings & auto-CMYK conversion
    \usepackage[cmyk]{xcolor} or \selectcolormodel{cmyk} will reconfigure pgfplots to use CMYK (document-wide)
- new feature (advanced audience only): programmatic access to data coordinates during the visualization phase
	-> allows much more customization for error bars, stacked plots, nodes near coords.
- wrote beginner tutorials
- fixed bug: error bars and point meta did not work together
- fixed bug: stacked plots did not respect 'visualization depends on'

- new feature: statistics library with boxplot handler (both boxplot prepared and automatic computation)
- fixed bug: 3d centered axis lines and label placement (requires compat=1.8 or higher)
- fixed bug: axis lines and placement of labels, tick scale labels, and reversed axes
    (requires compat=1.8 or higher)
- fixed bug: filtering out coords from a mesh plot failed
- fixed bug: every legend image post was not respected inside of \ref{plotlabel}
- fixed bug: high-order patches computed the shader=flat mean in a wrong way.
- fixed bug: remember picture inside of pgfplots axes failed (due to cell picture)
- fixed bug: now, the tick scale label will be omitted if there are no ticks
- fixed bug: axis box path was not closed
- fixed bug: the bounding box was non-empty even if the axis was hidden.
- fixed bug: auto-alignment of nodes near coords failed for xbar plots
- fixed bug: providing bar width / bar shift in terms of axis units did
    not work with [xy]bar and nodes near coords
- fixed bug: transformation 'data cs=cart' -> polar is more robust now
- fixed bug: code did not compile against pgf 2.00
- fixed bug: patch plot lib and shader=interp,patch type=biquadratic
- fixed bug: context path searching issue (pgfplots.lua)
- fixed bug: shader=interp and dvips driver 
- fixed bug: error bars with explicit relative input failed


- added feature: 'bar shift' and 'bar width' can now be expressed in terms of axis units (compat=1.7 or higher)
- fixed incompatibility regression pgfplots 1.6.1 pgf 2.10: layers
- fixed incompatibility pgfplots and imakeidx
- added feature: 'enlargelimits={abs=1cm}', i.e. enlarge by dimension rather than unit
- patchplots lib: added patch type=bicubic
- patchplots lib: added support for global paths (fillable)
- patchplots lib: added patch type sampling feature
- patchplots lib: improved usability (documentation and improvements)
- fixed path issues in context: moved lua input file to tex/generic
- fixed bug: \ref{legendimage} inside of legend text was wrong.


- fixed incompatibility lualatex,shader=interp, and german package (introduced in 1.6)


- added support for layered graphics (main use case: multiple axes and layers)
- added support for second colormap in mesh plots (mesh/interior colormap name)
- added support for scopes inside of axes
- contour plots: added ability to provide list of discrete labels (mesh/levels)
- empty lines are interpreted as interruptions in data plots (was undocumented since 1.4)
- added more scaling options to 'scale mode=scale uniformly' (affects axis equal in 3d
  and \addplot3 graphics)
- fixed wrong implementation of 'axis equal' and 'unit vector ratio' in 3d
  (backwards compatible for 2d, but not for 3d - the 3d implementation was plain wrong)
- fixed incompatibility of lualatex and shader=interp
- fixed bugs/added features around \addplot3 graphics
- fixed bug: colorbar did not support ymode=log
- fixed a couple of minor bugs
