PPL makes no difference to colour scheme - IPython 2.0.0 / Python 3.4 / PPL 0.1.7 / MPL 1.3.1 #54

Closed andrewclegg closed 10 years ago

andrewclegg commented 10 years ago

I have a notebook started with --pylab inline and a script that looks like this:

import prettyplotlib as ppl

np.random.seed(12)

fig, ax = plt.subplots(1)

ppl.hist(ax, np.random.randn(1000))

But the output seems to render using the default matplotlib colours:

Am I doing something wrong, or is there a version incompatibility somewhere?

This is on Ubuntu 12.04, Python 3.4, and here is the output of pip --list:

I get the same result with python 2.7.6 and the rest of the libs at the same version

alvaroribas commented 10 years ago

Same problem with python 2.7.5 and matplotlib 1.2.1

olgabot commented 10 years ago

This is very strange... I'm looking into this

If the colors aren't working for you, can you try running the tests?

cd prettyplotlib cd tests for py in $(ls test_*.py); do python $py ; done

Uh, awful output. Here is the result:

llimllib commented 10 years ago

OTOH, all tests pass for me

olgabot commented 10 years ago

@aribas thanks for checking. It looks like some of the tests are failing because this should really require matplotlib>=1.3.1, for eventplot, and others because the six module is required. Can you try making those upgrades? I'll update the requirements.

Also, next time there's output >20 lines or so, do you mind making it a gist on gist.github.com? Just to keep the big output separate from the discussion.

@llimllib Hmm... Are you on Windows/OSX/GNU/Linux?

llimllib commented 10 years ago

@olgabot Mac Mavericks 10.9.2

olgabot commented 10 years ago

Hmm this is very weird. I'm getting a similar error in my homebrew python but don't get it when I use a virtualenv. There must be some kind of conflict going on.

alvaroribas commented 10 years ago

@olgabot Sorry, I didn't know about gist. I guess I just have to share the link, right? https://gist.github.com/aribas/75d475391b3cc7828cd5

I upgraded matplotlib and six, still get some failures.

llimllib commented 10 years ago

@olgabot I get the same thing, it works fine in a virtualenv. Very weird.

cherepaha commented 10 years ago

I've updated to v. 0.1.7 and now have the same problem (Ubuntu 12.04, python 2.7.3, matplotlib 1.3.1). There is also another problem that did not occur before upgrade, so I think it may be relevant in resolving the problem with colors (just let me know if it deserves a new issue). The problem is basically that when I set the axis scale to logarithmic, ticks appear on that axis (but not on the other) figure_1

andrewclegg commented 10 years ago

Unfortunately this hasn't fixed it for me, but I don't think I can reopen the ticket.

I've upgraded to fc04d6e4f5edf1d402f51abeacc0dfd5132f60be which is 4 revisions after the changes pulled in #61, but I still get a barplot with the standard colours as shown at the top of this page.

All the tests pass for me.

You can reproduce this via Snake Charmer if that helps -- download it and install it as described in the readme, then create a new iPython notebook and run the example I attached to the original ticket. The only difference is, Snake Charmer no longer uses the --pylab argument to ipython, so you have to add

import matplotlib.pyplot as plt
import numpy as np

to the top of the example.
