Changes beyond 0.99.xΒΆ

  • The default behavior of matplotlib.axes.Axes.set_xlim(), matplotlib.axes.Axes.set_ylim(), and matplotlib.axes.Axes.axis(), and their corresponding pyplot functions, has been changed: when view limits are set explicitly with one of these methods, autoscaling is turned off for the matching axis. A new auto kwarg is available to control this behavior. The limit kwargs have been renamed to left and right instead of xmin and xmax, and bottom and top instead of ymin and ymax. The old names may still be used, however.
  • There are five new Axes methods with corresponding pyplot functions to facilitate autoscaling, tick location, and tick label formatting, and the general appearance of ticks and tick labels:
  • The matplotlib.axes.Axes.bar() method accepts a error_kw kwarg; it is a dictionary of kwargs to be passed to the errorbar function.
  • The matplotlib.axes.Axes.hist() color kwarg now accepts a sequence of color specs to match a sequence of datasets.
  • The EllipseCollection has been changed in two ways:
    • There is a new units option, 'xy', that scales the ellipse with the data units. This matches the :class:'~matplotlib.patches.Ellipse` scaling.
    • The height and width kwargs have been changed to specify the height and width, again for consistency with Ellipse, and to better match their names; previously they specified the half-height and half-width.
  • There is a new rc parameter axes.color_cycle, and the color cycle is now independent of the rc parameter lines.color. matplotlib.Axes.set_default_color_cycle is deprecated.
  • You can now print several figures to one pdf file and modify the document information dictionary of a pdf file. See the docstrings of the class matplotlib.backends.backend_pdf.PdfPages for more information.
  • Removed configobj and enthought.traits packages, which are only required by the experimental traited config and are somewhat out of date. If needed, install them independently.

  • The new rc parameter savefig.extension sets the filename extension that is used by matplotlib.figure.Figure.savefig() if its fname argument lacks an extension.

  • In an effort to simplify the backend API, all clipping rectangles and paths are now passed in using GraphicsContext objects, even on collections and images. Therefore:

                     clippath_trans, paths, all_transforms, offsets,
                     offsetTrans, facecolors, edgecolors, linewidths,
                     linestyles, antialiaseds, urls)

draw_image(self, x, y, im, bbox, clippath=None, clippath_trans=None)

  • There are four new Axes methods with corresponding pyplot functions that deal with unstructured triangular grids:
