Fix issue #4345: graphics test failure
closes #4345
The `test_time_series_plot_color_with_empty_kwargs` method in `test_graphics.py` uses the matplotlib default color cycle rather than 'r', 'g', and 'b'.

can you add release notes `doc/source/release.rst` and then whatever you add there please put in `doc/source/v0.13.0.txt`? thanks
 also can you hook up travis-ci?
 I have no idea how to do that and I don't really have time to do it right now.
 https://github.com/pydata/pandas/wiki/Testing#hook-up-travis-ci
 I set up Travis and pushed to try to trigger the build but it didn't seem to work.
 @nfoti no it's building correctly :ok_hand: 
 now we just wait to see if it passes
 here's a link https://travis-ci.org/nfoti/pandas/builds/9479583 if u want 2 watch
 Ah, I was just impatient and it hadn't started yet.
 btw thanks for setting it up, hope it wasn't too much of a pain
 No problem.  The link you sent was very helpful.

 @nfoti Can you rebase and squash or fixup to a single commit after you're finished? You can rebase on top of master with

``` sh
git remote add upstream git://github.com/pydata/pandas.git
git fetch upstream
git rebase upstream/master
```

Merge conflicts may occur but they will probably just be in release notes or v0.13.0.txt so should be easy to resolve.

Then, to squash/fixup do

``` sh
git rebase -i upstream/master
```

Thanks.
 I followed the rebase and fixup instructions.  The history is a bit messy though.
 okay here's some more `git` to fix up the history

``` sh
git reset HEAD~4 # go back 4 commits but keep your changes
git stash # put the changes in the stash
git fetch upstream # just to make sure
git reset --hard upstream/master # reset hard to master
git stash pop # put your changes back
git add . # add them
git commit -m'YOUR MESSAGE HERE' # commit the changes
git push --force # force push because you've rewritten history
```
 The stash is your (my?) best friend. I use it _all_ the time, especially if I screw something up. Downside: if you don't tightly regulate your stash then you can easily accumulate many pages of stash commits that are so old that you've completely forgotten what those patches were about. Of course, you can always do `git stash show -p stash@{stash_number}` but that can take a long time for a large # of stashes.
 Thanks for the help.  The history looks much better now.  I'll read up on
stashes.

 sure thing
 Done and I rebased onto `upstream/master`, but I'm not sure if I did it correctly.  Let me know what I need to do to fix the history.
 history looks ok
 Great!  Let me know if you need anything else.
 I removed the conflict markers from the file you mentioned.  Sorry that I forgot them there.  I rebased onto the new changes and squashed all of my commits into one.  I think this does it, unless the conflict markers got reintroduced.

Thanks.
 you'll need to rebase again

``` sh
git reset 599e733 # go back to your commit
git reset --hard
git reset HEAD~1 # peel off your commit
git stash # put the changes in the stash
git fetch upstream # just to make sure
git reset --hard upstream/master # reset hard to master
git stash pop # put your changes back
git add . # add them
git commit -m'YOUR MESSAGE HERE' # commit the changes
git push --force # force push because you've rewritten history
```
 Sorry about that.  I've re-rebased and checked that there were no merge
conflict tags remaining.

 @nfoti thanks!
