Log message:
Update print/texpgfplots and print/texpgfplotsdoc to 1.12, from
Leonardo Taccari in PR 49818.
Changes:
1.12: scalability + performance
 scalability: reduced TeX memory consumption for huge inline tables
 scalability: lualatex allows bigger 3d graphics
 scalability: lualatex now reduces compilation time for huge 3d graphics
(requires \pgfplotsset{compat=newest} at the time of this writing)
surf shader=faceted: time reduced to 61% of pdflatex
(\addplot3[surf,samples=70] {exp(x^2y^2 +x*y)})
surf shader=interp: time reduced to 25% of pdflatex
(\addplot3[surf,shader=interp,samples=70] {exp(x^2y^2 +x*y)})
surf shader=interp, parametric: time reduced to 36% of pdflatex
(\addplot3[surf,shader=interp,z buffer=sort, samples=50,domain=
1:0,y domain=0:2*pi] ({sqrt(1x^2) * cos(deg(y))}, {sqrt( 1x^2 ) * sin(deg(y))}
, x);)
surf shader=faceted, parametric: time reduced to 40% of pdflatex
(\addplot3[surf,z buffer=sort, samples=50,domain=1:0,y domain=0
:2*pi] ({sqrt(1x^2) * cos(deg(y))}, {sqrt( 1x^2 ) * sin(deg(y))}, x);)
 scalability: lualated now reduces compilation time for boxplots.
10000 input points from table: time reduced to 23% of pdflatex
 fixed bug: 3d axes where all axes used log scale produced compile failure
 fixed bug: axis equal did not respect "disabledatascaling"
 fixed bug: mesh legend was confused by color input=explicit
 fixed bug: colorbar style did not reset zmin/zmax
 fixed bug: memory allocation in FPU consumed too much memory
 fixed bug: boxplots: removed compilation error due to spurious spaces in optio
ns list
 fixed bug: boxplots: now uses standard quantile estimators: has all 9 estimato
rs of R and uses the same as in Excel as default (as of compat=1.12)
 fixed bug: boxplots: sometimes failed to compute boxplot statistics for specia
l inputs
 fixed bug: boxplots: now, it sets 'mark=*' for outliers if there is no mark (c
ompat=1.12)
 fixed regression: compat=1.11 broke arcs inside of axis
 new feature: ensured that arcs inside of axis make use of 'axis cs' and 'axis
direction cs' automatically
 new feature: ensured that (0:1) is evaluated with axis cs
 fixed bug: precision of transformation cartesian to polar was too low (added a
tan2 to fpu)
 fixed bug: z buffer caused 'mesh legend' to produce a compile error
 new feature: added 'y filter/.expression={y==3 ? nan : y}' to simplify coordin
ate filters
1.11: usability + bug fixes.
 new feature: "hide obscured x ticks=false" to disable the feature \
which hides
ticks
 simplified UI for symbolic coords: now, it accepts unexpandable
dictionary entries including umlauts, undefined macros, math mode, ...
 simplified UI for symbolic coords: added magic prefix
[normalized]<number> to allow something like xmin={[normalized]0.7}
 simplified UI for custom annotations: one does not need to say "axis \
cs" any l
onger;
coordinates like (1,2) are now automatically interpreted as (axis cs:1,2)
 new feature: 'type ticklabels with struts' improves baseline alignment of tick
labels
 new feature: 'trig format plots=rad' allows to use radians in trigonometric ev
aluations
 simplified 'external lib': added driver autodetection for pdflatex, lualatex,
xelatex, dvips
(\usepgfplotslibrary{external}, or, with the next PGF release, \usetikzl
ibrary{external})
 simplified UI for \addplot coordinates: now, it expands macros as it goes.
 new feature: 'intersection segments' now accepts negative indices to count fro
m the last backwards
 simplified UI: 'intersection segments' now accepts new syntax with 1based ind
ices (old 0based are still supported)
 fixed bug: fillbetween has had a problem with pins on input paths
 fixed bug: now, 'stacked ignores zero' is no longer applied to error bars.
 fixed bug: tick lines were drawn incorrectly for centered axis lines in 3d

correct layers for grid lines etc.
 fixed bug: z grid style was applied to y grid style
 fixed bug: using 'x=1cm' failed to work in axis descriptions (legends)

 fixed bug: bounding box of shader=interp was wrong if there were transformatio
ns.
 fixed bug: added support for \addplot graphics in ConTeXt
 fixed bug: external lib failed to work with dvips (since PGF 3.0.0 I suppose);
now it produces correct bounding boxes
 fixed bug: \pgfplotstablenew can now overwrite existing tables.
 fixed bug: extra ticks near intersections of axis lines were hidden
 fixed bug: 'intersection segments' did not work with 'cycle'
 fixed bug: 'intersection segments' did not update the last tikz point
 fixed bug: tick lines/grid lines have been clipped when they were near the bou
ndary
 fixed bug: soft clip decoration failed to apply the transformation matrix
 fixed bug: polar axes and units library resulted in broken bounding box
 fixed bug: \addplot[stack plots=false] used to work up to 1.8, but failed unti
l now. Fixed.
 fixed bug: hist/density was broken since some time
1.10:
 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 ba
r plots
1.9:
 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 th
e middle and print the increment (compat=1.9)
 new feature: stacked bar plots suppress empty increments (compat=1.9).
 new feature: 'scatter/position=relativeabsolute' allow to position 'nodes nea
r coords' absolutely.
usecase: bar plots + nodes near coords which are at, say, y=0 rather than th
eir y value
 new feature: integration of smooth shadings & autoCMYK conversion
\usepackage[cmyk]{xcolor} or \selectcolormodel{cmyk} will reconfigure pgfplo
ts to use CMYK (documentwide)
 new feature (advanced audience only): programmatic access to data coordinates
during the visualization phase
> allows much more customization for error bars, stacked plots, nodes n
ear 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'

e)
