Changes for 0.91.0

  • Changed cbook.is_file_like to cbook.is_writable_file_like and corrected behavior.

  • Added ax keyword argument to :func:.pyplot.colorbar and :meth:.Figure.colorbar so that one can specify the axes object from which space for the colorbar is to be taken, if one does not want to make the colorbar axes manually.

  • Changed cbook.reversed so it yields a tuple rather than a (index, tuple). This agrees with the Python reversed builtin, and cbook only defines reversed if Python doesn't provide the builtin.

  • Made skiprows=1 the default on csv2rec

  • The gd and paint backends have been deleted.

  • The errorbar method and function now accept additional kwargs so that upper and lower limits can be indicated by capping the bar with a caret instead of a straight line segment.

  • The :mod:matplotlib.dviread file now has a parser for files like psfonts.map and pdftex.map, to map TeX font names to external files.

  • The file matplotlib.type1font contains a new class for Type 1 fonts. Currently it simply reads pfa and pfb format files and stores the data in a way that is suitable for embedding in pdf files. In the future the class might actually parse the font to allow e.g., subsetting.

  • matplotlib.ft2font now supports FT_Attach_File. In practice this can be used to read an afm file in addition to a pfa/pfb file, to get metrics and kerning information for a Type 1 font.

  • The AFM class now supports querying CapHeight and stem widths. The get_name_char method now has an isord kwarg like get_width_char.

  • Changed :func:.pcolor default to shading='flat'; but as noted now in the docstring, it is preferable to simply use the edgecolor keyword argument.

  • The mathtext font commands (\cal, \rm, \it, \tt) now behave as TeX does: they are in effect until the next font change command or the end of the grouping. Therefore uses of $\cal{R}$ should be changed to ${\cal R}$. Alternatively, you may use the new LaTeX-style font commands (\mathcal, \mathrm, \mathit, \mathtt) which do affect the following group, e.g., $\mathcal{R}$.

  • Text creation commands have a new default linespacing and a new linespacing kwarg, which is a multiple of the maximum vertical extent of a line of ordinary text. The default is 1.2; linespacing=2 would be like ordinary double spacing, for example.

  • Changed default kwarg in matplotlib.colors.Normalize to clip=False; clipping silently defeats the purpose of the special over, under, and bad values in the colormap, thereby leading to unexpected behavior. The new default should reduce such surprises.

  • Made the emit property of :meth:~matplotlib.axes.Axes.set_xlim and :meth:~matplotlib.axes.Axes.set_ylim True by default; removed the Axes custom callback handling into a 'callbacks' attribute which is a :class:~matplotlib.cbook.CallbackRegistry instance. This now supports the 'xlim_changed' and 'ylim_changed' Axes events.
