Version 1.4.0

Over the past few months we have added several major new features and with the help of our users have been able to address a number of bugs and inconsistencies. We have closed 57 issues and added over 1100 new commits.

Major new features:

  • Data API: The new data API brings an extensible system of to add new data interfaces to column based Element types. These interfaces allow applying powerful operations on the data independently of the data format. The currently supported datatypes include NumPy, pandas dataframes and a simple dictionary format. (PR #284)
  • Backend API: In this release we completely refactored the rendering, plotting and IPython display system to make it easy to add new plotting backends. Data may be styled and pickled for each backend independently and renderers now support exporting all plotting data including widgets as standalone HTML files or with separate JSON data.
  • Bokeh backend: The first new plotting backend added via the new backend API. Bokeh plots allow for much faster plotting and greater interactivity. Supports most Element types and layouts and provides facilities for sharing axes across plots and linked brushing across plots. (PR #250)
  • DynamicMap: The new DynamicMap class allows HoloMap data to be generated on-the-fly while running a Jupyter IPython notebook kernel. Allows visualization of unbounded data streams and smooth exploration of large continuous parameter spaces. (PR #278)

Other features:

  • Easy definition of custom aliases for group, label and Dimension names, allowing easier use of LaTeX.
  • New Trisurface and QuadMesh elements.
  • Widgets now allow expressing hierarchical relationships between dimensions.
  • Added GridMatrix container for heterogeneous Elements and gridmatrix operation to generate scatter matrix showing relationship between dimensions.
  • Filled contour regions can now be generated using the contours operation.
  • Consistent indexing semantics for all Elements and support for boolean indexing for Columns and NdMapping types.
  • New hv.notebook_extension function offers a more flexible alternative to %load_ext, e.g. for loading other extensions hv.notebook_extension(bokeh=True).

Experimental features:

  • Bokeh callbacks allow adding interactivity by communicating between bokehJS tools and the IPython kernel, e.g. allowing downsampling based on the zoom level.

Notable bug fixes:

  • Major speedup rendering large HoloMaps (~ 2-3 times faster).
  • Colorbars now consistent for all plot configurations.
  • Style pickling now works correctly.

API Changes:

  • Dimension formatter parameter now deprecated in favor of value_format.
  • Types of Chart and Table Element data now dependent on selected interface.
  • DFrame conversion interface deprecated in favor of Columns pandas interface.

We'd again like to thank our growing user base for all their input, which has helped us in making the API more understandable and fixing a number of important bugs.

Highlights/Features:

  • Allowed display of data structures which do not match the recommended nesting hierarchy (67b28f3, fbd89c3).
  • Dimensions now sanitized for .select, .sample and .reduce calls (6685633, 00b5a66).

API Changes

  • Renamed key_dimensions and value_dimensions to kdims and vdims respectively, while providing backward compatibility for passing and accessing the long names (8feb7d2).
  • Combined x/y/zticker plot options into x/y/zticks parameters which now accept an explicit number of ticks, an explicit list of tick positions (and labels), and a matplotlib tick locator.
  • Changed backend options in %output magic, nbagg and d3 are now modes of the matplotlib backend and can be selected with backend='matplotlib:nbagg' and backend='matplotlib:mpld3' respectively. The 'd3' and 'nbagg' options remain supported but will be deprecated in future.
  • Customizations should no longer be applied directly to Store.options; the Store.options(backend='matplotlib') object should be customized instead. There is no longer a need to call the deprecated Store.register_plots method.
