David,

A major problem with SVG output as default is that for image-type plots 
(e.g., pcolormesh) it yields enormous output that is very slow to 
render.  The advantage of png is that although it is not optimal from a 
visual standpoint, it works reliably and predictably with everything. 
Therefore it is a sensible default.

David,

The attached scripts, which seem to be a minimal example of what you 
describe, work for me with matplotlib 1.2.1, MacOSX backend.

There is a very good way to use otf and ttf fonts in LaTeX and matplotlib,
  which you might like:

http://matplotlib.org/users/pgf.html

With this method you can use LuaLaTeX, or XeLaTeX, both of which have
options to load OTF or TTF fonts. This would be done via the LaTeX preamble
in the .matplotlibrc file, which might be storred in the home directory on
your Mac (just a guess, since I do not normally use matplotlib with a Mac).

This might be a bit of a steep learning curve if you haven't done anything
more serious with matplotlib, but you won't have to install the fonts,
which, I must agree, *is* painful.

Hope that helps,

Ignas

Hello,

I was just wondering what is wrong with using the name rc (because it's just a
convention how to name your variable)? It is still used quite widely on UNIX
(and Mac OS is still a UNIX :)). Also, it is documented here:

http://matplotlib.org/users/customizing.html

I see your point though, in this document there isn't a single word, that the
'rcParams' stand more or less for the parameters which are initialised when
matplotlib loads or starts plotting.

Do not know if we should change this page to add some explanation, why we use
*rc settings*.

Ignas

I am trying to execute (with execfile) a script A.py containing matplotlib
plotting commands from within a script B.py.

Within B.py,  I do  execfile("A.py")

The A.py script runs correctly, except that no plot is shown.

I have checked that the A.py script does plot (to a separate window) when
run
with python A.py from the terminal.
A.py does include plt.show()

Could an expert on backends help, please!

Thanks
David.

Breaking news from the MathJax site:

The *SVG output processor* is new in MathJax version 2.0, and it uses Scalable
Vector Graphics to render the mathematics on the page.

Mike: Could we use this to finally render all text in STIX *without* using
an external TeX installation? This would be fantastic!

Sure, I'm very happy to help.

First let me return to the fonts issue.
I had been misunderstanding the rcParams (this seems to be a recurring
problem at the moment ;) - some new documentation is definitely required; I
will try to get round to add it to my matplotlib.settings notebook).

The fuzziness I referred to was indeed a retina issue, stemming from the
fact *that the default output format is still PNG*. It seems to me that
these days the default output should be SVG, which immediately resolves all
retina issues!! (And a lot of other issues, it seems to me.)

The current status of retina support is actually reasonable. There are two
options:

%load_ext retina
%config InlineBackend.figure_format = 'retina'

In the absence of tab completion for %load_ext and %config, and not
understanding the code, I am not sure if these are synonyms or not. But the
effect is to have PNGs produced with twice the vertical and horizontal
resolution. (The problem comes if, for example, these are included in
output sent to nbviewer, in which case they appear twice as large.)

One STIX font question remains: How can I get the text of the tick labels
and other things to also be in STIX?
settings['font.family'] = 'stix'
does not work, apparently.

And could the default font finally be changed to something else? What are
the licensing requirements for the font? Is it distributed with matplotlib,
or how does it work?

David.

I'm not really sure why the configobj dependency doesn't resolve properly.
As they say: pull requests are welcome. ;)

This is all *crying out* to be dropped straight into matplotlib proper!

Here's a PR to add the style sheets from mpltools:

Just saw Eric's post (but the mailing list has yet to update to send me the
individual posts apparently, hence the new title of this email).

+1 (or +100) for using 'settings' !

Here is the new version of my notebook:

http://nbviewer.ipython.org/urls/raw.github.com/dpsanders/IPython-notebooks/master/matplotlib_settings.ipynb

*Boy*, does the IPython Notebook desperately need find and replace!!

This is already implemented! The problem is, it's hidden away in the
mpltools toolkit:

http://tonysyu.github.io/mpltools/

which nobody seems to know about or use, which is a great shame, since it's
first class -- great job, Tony!

The first example there is:

>>> from mpltools import style>>> style.use('ggplot')

and then the plot is suddenly jaw-droppingly beautiful!

This is achieved with style files which just have lists of matplotlib
params like this:

patch.linewidth = 0.5
patch.facecolor = '#348ABD'  # blue
patch.edgecolor = '#EEEEEE'
patch.antialiased = True

These are parsed using the ConfigObj package (this package parses config
files of this type).

Somebody (Chris?) tweeted something about the Vega package earlier:
http://trifacta.github.io/vega/

They seem to have these kind of things solved already (disclaimer: I only
browsed briefly their site) using JSON, but actually Tony's approach seems
like a winner.

mpltools may be installed with

> pip install ConfigObj
> pip install mpltools

[For some reason the dependency on ConfigObj is not registered in mpltools.
Tony, are you the packager?]

This is all *crying out* to be dropped straight into matplotlib proper!

Hi,

Apparently I was misusing the list by having digests sent -- apologies.
I have turned this off.

Maybe the following got lost in the resulting noise:

I completely agree that the current defaults need updating.

In my opinion, 'rcParams' is a bad name, since it conjures up dusty
configuration files hidden in obscure corners which must never be modified.

Indeed, http://en.wikipedia.org/wiki/Run_commands says that the origin of
'rc' is:

> The term *rc* stands for the phrase "*run commands*". It is used for any
file that contains
> startup information for a command. It is believed to have originated
somewhere in 1965

None of these three 'features' of the phrase 'rc' have *anything*  to do
with matplotlib.
'rc' evokes fond memories of hacking for a few; it evokes nothing and reeks
of alienating hack-speak to the rest.

I thus suggest that we replace rc_Params -> mpl_params.

As an example, I have made some narrative documentation, which can be
included in the matplotlib documentation (let's discuss where, Nelle and
Mike), on how to tweak mpl_params:

http://nbviewer.ipython.org/urls/raw.github.com/dpsanders/IPython-notebooks/master/mpl_params.ipynb


This is, if you like, a cosmetic change, but I think it's an important
psychological one.
It also avoids the visual interruption caused by the capital 'P'.

Of course, anybody is free to make this change in the way I have in the
notebook by creating an alias, mpl_params = rcParams.  But I am advocating
for changing uniformly to mpl_params (or a similar phrase) in the
documentation.

David

'image.cmap' -- nice! Shows how much I know :)

I don't fully agree with Eric that changing the defaults should be treated
as an API break -- yes, it may irritate a minority of users, but their code
will still run. I'd flip around your argument for the role of rcParams and
customization: the majority user is probably someone who doesn't know much
about rcParams, or all the ways plots can be customized. *That* is the use
case to optimize, not the "legacy" users invested in the current style.

However, default tweaking need not be painful. As has been mentioned, a
first step would be an easier way to change a whole set of rcParams:
something like mpl.set_style('style-name'). As long as one style is
'classic', users can keep the current style for as long as they want. It's
a one line fix, and could even be rcParams-settable.

With such a framework, it would be possible for people to contribute new
styles that ship with MPL, and users could change styles without having to
find (and potentially merge) rcParams files from the web. Finally, people
could nominate that mature styles be made default (you could even assign
version numbers to track the default style as it evolves towards visual
awesomeness)

Jet is terrible for so many reasons, but it can be modified (unless I
misunderstand):

image.cmap : gray

I'm all for changing the current defaults.

Yes, mpl_params is more descriptive and easy to remember.  rcParams is 
ugly, obscure, and archaic.  It will have to remain available for a long 
time, but I don't object to changing standard usage to a nicer name. 
There might even be a better name than "mpl_params"--"settings" comes to 
mind, or maybe "style".

As for parameter tweaking: the defaults shipped with mpl should be 
changed only rarely, but we should make it as easy as possible for users 
to customize plots, including coming up with good combinations of style 
parameters.  In some cases it makes sense to do this via a matplotlibrc 
file, in other cases it is better to do the parameter setting explicitly 
at the top of a script.

Regarding defaults, note that I said "rarely", not "never".

The whole rc system could use a good review--maybe resulting in lots of 
changes, maybe not--so I welcome the attention you are directing to it.

Sorry, I meant to send the nbviewer version, and call it a notebook, not a

OK, sorry for the noise. The site is beautiful and functional, and I'm very
glad that you got the discussion flowing!

I agree about the defaults, we desperately need to modernize the look of
the plots to be competitive with ggplot2 etc.

I really do object to the 'rc' terminology.
According to http://en.wikipedia.org/wiki/Run_commands:

> The term *rc* stands for the phrase "*run commands*". It is used for any
file that contains startup information for a
> command. It is believed to have originated somewhere in 1965

And this is my problem with 'rc':  it brings to mind an arcane config file
hidden away somewhere that has a terrible syntax and must not be touched.

As Chris and Adrian have emphasized, the point is that we *should* be
tweaking away at the parameters all the time.
I propose to rename as  mpl_params=rcParams

At https://gist.github.com/dpsanders/6047005 I have uploaded a short script
which should be added to the matplotlib documentation, where I show how it
looks to use mpl_params.
I think it is much clearer and more inviting to tweak!

David.
