# What's new in Matplotlib 0.99 (Aug 29, 2009)¶

Table of Contents

## New documentation¶

Jae-Joon Lee has written two new guides Legend guide and Advanced Annotations. Michael Sarahan has written Image tutorial. John Hunter has written two new tutorials on working with paths and transformations: Path Tutorial and Transformations Tutorial.

## mplot3d¶

Reinier Heeres has ported John Porter's mplot3d over to the new matplotlib transformations framework, and it is now available as a toolkit mpl_toolkits.mplot3d (which now comes standard with all mpl installs). See 3D plotting and The mplot3d Toolkit.

## axes grid toolkit¶

Jae-Joon Lee has added a new toolkit to ease displaying multiple images in matplotlib, as well as some support for curvilinear grids to support the world coordinate system. The toolkit is included standard with all new mpl installs. See axes_grid1, axisartist, Overview of mpl_toolkits.axes_grid1 and axisartist

## Axis spine placement¶

Andrew Straw has added the ability to place "axis spines" -- the lines
that denote the data limits -- in various arbitrary locations. No
longer are your axis lines constrained to be a simple rectangle around
the figure -- you can turn on or off left, bottom, right and top, as
well as "detach" the spine to offset it away from the data. See
Spine Placement and
`matplotlib.spines.Spine`
