1.7.3 (not yet released)

Features

  • Plots now show inline in jupyter notebooks.
  • Added docs/examples for jupyter notebooks.
  • Can set the default background color for plots using bgcolor = in the [default] section of the config. This default effects plots shown on the screen and non-antialiased plots written with write_img. The default can specifically be overridden in the [screen] section and the new section configuring non-anti-aliased plots [image_noaa].
  • New config section for anti-aliased images [image] where currently you can set the resolution, which defaults to dpi = 100. This can be overridden in call to write(..., dpi=)
  • New config section for non-anti-aliased images [image_noaa] where currently you can set the default width =, height=, bgcolor= and color = . Default width,height is 640. The colors default to those set in the [default] section.
  • The write_img function can now be called with just the filename, since the default width,height can now be set in the [image_noaa] section. The other arguments can now be sent with keywords (old style still supported).
  • Label for plot components like Points can be set at construction

Bug Fixes

  • make ScreenRender close itself after leaving the context manager (or being cleaned up). This prevents a seg fault that could occur when the X11 device was open and an error occured, and the device was not then closed. This was basically a mistake on my part thinking that close would close the window, so I had not deleted it.
  • Fixed keyword conflict in lightweight plotting routines.

Removed Features

  • removed the persistent = yes feature for X11 windows. This never worked. It may be re-implemented in the future.

1.7.2 (14 Mar 2017)

Features

  • Added += syntax for adding components to a PlotKey.
  • Added += syntax for adding components to containers.
  • Added Polygon component.

Bug Fixes

  • Added /usr/X11 to search path for linking plotutils. (Thank you @smaret!)

Code Changes

  • Updated examples to use new += syntax.
  • Updated code to PEP8 with autopep8.
  • Updated travis-ci to ship to pypi on tags.
  • Added MANIFEST.in file to include README.rst in the package.

1.7.0 (08 Mar 2017)

Features

  • Increased default screen size to 640x640.
  • Changed default font to HersheySerif.
  • Changed default to non-persistent windows.
  • Added new write functions for anti-aliased images.
  • Added smooth keyword to histogram.
  • Added option to change panel ratios in FramedArray using row_fractions and col_fractions keywords.
  • Visibility of panels in FramedArray can be controlled with the visibility attribute, arr[i,j].visible=False.
  • Added \odot to latex conversion, for sun symbol.
  • New func.plot function with more functionality.
  • Major classes and functions documented. This facilitates checking docs from an interactive session, e.g. help() or ? in ipython.
  • New documentation on GitHub wiki.

Bug Fixes

  • Fixed plotting of vertical and horizontal lines on log axes.
  • Fixed bug in bounding box unions computing minimum.
  • Added try: finally: blocks around compose operations. Fixes segfault when an exception is thrown while composing and more plotting is attempted.
  • Fixed bug in DataArc/PlotArc.

Code Changes

  • Added Travis CI for testing.
  • Converted to new style classes.
  • Converted to extended calling syntax.
  • Moved to spaces instead of tabs.

Removed Code

  • Removed old C wrapper for GNU plotutils.
  • Removed old Makefile build system.
  • Removed matlab compatible interface.
  • Removed read_* I/O code from func.py.

1.6.7 (02 May 2012)

  • Fix segfault when libplot isn't built with X11 (reported by Daniel Ericsson & Sebastien Maret).

  • Move to github.

1.6.6 (27 Nov 2008)

  • Fixed issue that caused all images to be 570x570 on some systems, due to a change in the python2.5 C API.

  • Improved setup.py and Makefiles.

  • Contours can now be used with PlotKey.

  • Added Labels component. Similar to Points, but with text labels instead of symbols.

1.6.5 (20 Mar 2007)

  • Replaced Numeric with numpy.

1.6.4 (08 Mar 2004)

  • Phil Kromer contributed the new ColoredPoints and Density components. See example9.py for details.

  • Todd Fox contributed Makefiles for building with MS Visual C++.

  • Can now specify the width/height of postscript output, by passing (e.g.) width="5in" or height="10in" to the functions which produce postscript output. Default values are in the [postscript] section of config.ini. The old [printer]/paper option is now [postscript]/paper.

  • Added UpperLimits, LowerLimits components. These produce symbols with half-arrows indicating the true value is below/above the point.

  • Added TeX codes `,',^,",~ for character accents.

1.6.3 (16 Jul 2002)

  • Mike Romberg fixed bugs related to packaging biggles with imputil.

1.6.2 (23 May 2002)

  • Spiros Papadimitriou contributed an experimental piddle port.

  • You can now specify partial ranges for plots. So "p.xrange = 2, None" will set the lower bound of the plot p to be 2, and the upper bound will be guessed from the data contained in the plot.

  • Replaced "!= None" with "is not None" everywhere.

  • Fixed bug with added space in scientific notation ticklabels.

1.6.1 (14 Nov 2001)

  • Martin Lamar ported the code to Windows.

  • Replaced "== None" with "is None" everywhere (again thanks to Martin). This should fix crashes with recent versions of numpy.

1.6.0 (07 Nov 2001)

  • Clipping!

  • Better performance for plots with lots of data. Parts of the code were vectorized, and a new integrated libplot interface was written. Biggles no longer uses the python-libplot module.

  • Jamie Mazer contributed code for Matlab emulation, accessible by "import biggles.matlab".

  • Added the multipage() function for multipage postscript output. Thanks to Olivier Andrieu for the original patch.

  • Changed the default plot window size to 512x512 from 570x570.

  • Bug fixes: better tick generation on huge-ranged log axes; the "thousand tiny lines" problem with contour plots.

1.5.0 (31 Aug 2001)

  • Completely rewrote FramedPlot. Fully backward compatible with the old FramedPlot, it adds a tremendous number of new features. CustomFramedPlot is now deprecated.

  • Configuration options are now read when objects are instantiated, instead of during class definition. This means you can change them in the middle of a script, using the new configure() function.

  • Added read_rows(),read_matrix() functions. They read text data files, returning a list of rows and a matrix, respectively. Numeric Python arrays are returned by default. The readcolumn() function has been renamed read_column().

  • TeX font control sequences \it and \bf are now recognized. Spaces are no longer ignored during math mode.

  • You can now specify single characters as plotting symbols.

  • Added DataBox/PlotBox components.

  • Added .align_interiors option to Table.

  • Added .drop_to_zero option to Histogram.

  • Added .title_style attribute to all containers.

  • The container methods .save_as_XXX() were renamed .write_XXX(). While the old names are not deprecated, they will no longer appear in the documentation.

  • Bug fixes: fixed crash when used by a CGI script, dropped minus sign for axis labels which are powers of ten, compile problem on Suns.

1.4.0 (06 Mar 2001)

  • Biggles now requires the Numeric Python module, and is no longer a pure Python module.

  • Added support for contour plots with new Contours() component.

  • HammerAitoffPlot(): new & improved geodesic algorithm; added support for rotated coordinates.

  • Added FillAbove(), FillBelow() components. Fill*() objects now work with PlotKey().

  • More robust interactive session detection. The config.ini option "[screen] guess_interactive" has been renamed "persistent". Removed interactive() function.

  • Better tick guesses for log axes.

  • Bug fixes: apparent data scaling by FramedArray when aspect_ratio is set; several related to calculating limits.

1.3.0 (17 Dec 2000)

  • Breaks old Table cell{spacing,padding} values; multipying them by 100 should work in most cases.

  • Renamed Label{Data,Plot} -> {Data,Plot}Label, LineSlope -> Slope, and ErrorEllipses -> Ellipses. The old names still work but are deprecated.

  • {Line,Symbol}Key have been superceded by PlotKey and are now deprecated.

  • New plot type: CustomFramedPlot(). Similar to FramedPlot(), but allows finer control over the frame style.

  • New plot type: HammerAitoffPlot(). An equal-area projection of the sphere, Hammer-Aitoff plots are commonly used in astrophysics.

  • New FramedArray options: .uniform_limits & .cellspacing.

  • New components: Circle(s), Ellipse, Geodesic, Point, PlotInset, and PlotLine.

  • You can now specify a minimum fontsize with "fontsize_min" in config.ini.

  • Various speed improvements, bug fixes, and infrastructure work.

1.2.1 (31 Oct 2000)

  • Reorganized config.ini file.

  • The readcolumn() function can be configured to return Numeric arrays.

  • Added interactive() function to let users control X window behavior.

  • Fixed a couple of axis bugs triggered by very large limits.

1.2.0 (09 Oct 2000)

  • Added distutils setup.py file. [contributed by Berthold H�llmann]

  • Added FramedArray container for grouping similar plots.

  • Added SymmetricErrorBars[XY] helper functions.

  • You can now say "t[i,j]=x" instead of "t.set(i,j,x)" for Table objects.

  • Broke readcolumn() so users can pass in their own string -> number conversion functions. Also, readcolumn now ignores blank lines and those starting with a comment character.

  • When used interactively, biggles now reuses the same X window insteading of creating a new window each time .show() is called.

  • Fixed stupid printing bug.

1.1.0 (22 Sep 2000)

  • LineKey, SymbolKey, and Inset now take plot coordinates instead of data coordinates. Plot coordinates run from 0 -> 1 for each axis. Sorry about the breakage.

  • Inset coordinates now specify the frame location, not the bounding box. More breakage.

  • Replaced Label with LabelData & LabelPlot. LabelData works the same as Label, and LabelPlot takes plot coordinates instead of data coordinates.

  • Added LineSlope, Line[XY] components.

  • Added readcolumn() function. Returns a list of column values from a flat ASCII file.

  • More namespace cleanup.

1.0.3 (02 Sep 2000)

  • Fixed a couple of layout bugs. Handling of large tables and elongated plots is greatly improved. [thanks to Jamie Mazer]

  • .save_as_{eps,img}() now recognize the filename "-" as stdout.

  • Better log ticks.

  • Namespace cleanup.

1.0.2 (18 Aug 2000)

  • Top level layout overhauled. Ugly-hack-that-sorta-worked replaced with Elegant Solution. Naturally, it's quite a bit slower.

  • Added "cellpadding" and "cellspacing" to Table, similar to HTML tables.

1.0.1 (14 Aug 2000)

  • Prettier tick labels.

  • Fixed stupid aspect_ratio bug.

1.0.0 (12 Aug 2000)

  • First stable release.
