First release candidate for the 1.5.0 series

tacaswell · September 15, 2015, 3:59am

Please give it a try! (linux64 conda builds are available on the tacaswell
anaconda.org channel)

https://github.com/matplotlib/matplotlib/releases/tag/v1.5.0rc1

This release contains many new features. The highlights include:

  - the object oriented API will now automatically re-draw the figure when
working in the command line
  - automatic unpacking of labeled data into most plotting functions
  - arbitrary style cycling
  - four new perceptually linear color maps
  - mouse-over for pixel values with `imshow`
  - many new rcparams

In addition there are significant improvements to `nbagg` and a complete
overhaul of the c++ bindings to AGG.

Please see the drafts of the [full whats new](
http://matplotlib.org/devdocs/users/whats_new.html#new-in-matplotlib-1-5)
and [api changes](

Hi,

where do I upload the Windows binaries? Sourceforge?

What is the oldest supported numpy version? Numpy 1.6.2 no longer works.
I am building rc1 with numpy 1.8.2 (Py <= 3.4) and 1.9.2 (Py 3.5).

Numpy 1.6 should work, we are currently testing against it on travis.

And yes, please push the windows binaries to sourceforge.

Christoph,

It would also be useful to document any changes needed in the build
procedure for python3.5 on Windows. I don't know if the changes needed for
py3.5 impacts us or not, but it would be good to know that for sure.

Thanks,
Ben Root

PyArray_SetBaseObject is new in Numpy 1.7. You have to set the base by
hand in in 1.6.

An example is here:

Created an issue for the numpy regression

github.com/matplotlib/matplotlib

numpy incompatibility

opened 05:45PM - 15 Sep 15 UTC

closed 04:45PM - 26 Sep 15 UTC

tacaswell

Release critical

We have non np 1.6 compatible code in the gdk backend which we do not test on tr…avis. Issue reported by @cgohlke http://matplotlib.1069221.n5.nabble.com/Matplotlib-devel-First-release-candidate-for-the-1-5-0-series-tp46156p46166.html http://stackoverflow.com/questions/28499580/matplotlib-import-error-backend-gdk-soundefined-symbol-pyarray-setbaseobjec The code in question went in in https://github.com/matplotlib/matplotlib/pull/3665 which was in response to discussion at http://thread.gmane.org/gmane.comp.python.matplotlib.general/34771/focus=34771 Options here are: - fix code to address both issues (no idea how hard that would be) - up the minimal numpy until it works I am in favor of bumping the numpy version, but do not feel strongly.

The in-practice minimal version is currently 1.7

The only change is to have Visual Studio 2015 installed (the community
edition is free of charge).

A related issue: The matplotlib extensions for Python 3.5 depend on the
Visual Studio 2015 C/C++ runtime DLLs, specifically vcruntime140.dll and
msvcp140.dll. Vcruntime140.dll is installed with Python 3.5.0 final,
however not copied to virtual environments. Msvcp140.dll is not
distributed with Python 3.5.

Possible solutions:

1) ship msvcp140.dll in the matplotlib package directory. Python and
other packages might still fail to load, but that's not matplotlib's
problem. This is the preferred way to ship dependencies according to
Microsoft. I personally dislike shipping system DLLs next to extensions.
See also <http://stevedower.id.au/blog/building-for-python-3-5-part-two/>

2) require users to install the "Visual C++ Redistributable for Visual
Studio 2015"
<http://www.microsoft.com/en-us/download/details.aspx?id=48145>\. This
requires administrator privileges. In the long run this will be much
less trouble for users.

Could someone who uses backend_gdk actively and has numpy 1.6 test my
proposed fix? It compiles and imports for me, but that's not much of a
test yet. Drawing raster images should exercise the relevant code.

Hi,

Please give it a try! (linux64 conda builds are available on the tacaswell
anaconda.org channel)

Release v1.5.0rc1 · matplotlib/matplotlib · GitHub

This release contains many new features. The highlights include:

  - the object oriented API will now automatically re-draw the figure when
working in the command line
  - automatic unpacking of labeled data into most plotting functions
  - arbitrary style cycling
  - four new perceptually linear color maps
  - mouse-over for pixel values with `imshow`
  - many new rcparams

In addition there are significant improvements to `nbagg` and a complete
overhaul of the c++ bindings to AGG.

Please see the drafts of the [full whats
new](http://matplotlib.org/devdocs/users/whats_new.html#new-in-matplotlib-1-5)
and [api
changes](http://matplotlib.org/devdocs/api/api_changes.html#changes-in-1-5-0)

After some struggle, RC1 wheels up at http://wheels.scipy.org/

Built via : Travis CI - Test and Deploy with Confidence

If you're testing Python 3.5 you'll need the patched numpy 1.9.2 wheel
from nipy.bic.berkeley.edu :

pip install -f https://nipy.bic.berkeley.edu/scipy_installers numpy

Cheers,

Matthew

A minor suggestion: increase the the savefig.dpi when building the docs.
The examples look quite bad, especially the text looks very unsharp.

Another suggestion for 2.0: use another default font. Maybe Bitstream
Vera Sans just gets badly rendered and the freetype/agg combination of
matplotlib, but it looks unsharp for smaller fontsizes. Even for bigger
sizes it is still not a very nice font.
Tbh I don't know if there are usable free fonts as an alternative,
but maybe someone does know.
