Scipy2013 Sprint: Cleaning examples of api example

[gabraganca]

Worked on two examples.

• Barchart demo. I broke it in two; one with error and other without. Moved it do Statistics folder
• Fahrenheit and Celsius scale. Cleaned with help of @leouieda and changed to subplots_axes_and_figures folder.

[tonysyu]

Really Minor: Maybe move figure/axes definitions down with the rest of the plotting code (i.e. below the function defs). Also, I think the inline comments should be removed here. (Maybe ax1 -> ax_f, ax2 -> ax_c?)

[tonysyu]

Thanks for cleaning up some examples!

I think the fahrenheit/celsius scale example is more or less ready to go. (I had some minor comments, but nothing major.)

The barchart examples may need a bit more thought. The original example showed a few more features than just error bars. I'd be inclined to split the example up into barchart_demo and barchart_demo_features, where the latter retains more of the features of the original. In fact, barchart_demo.py in examples/pylab_examples (not examples/api) is a pretty clean version of this example.

As suggested in the MEP12 guidelines, you need to check whether the examples you move are referenced in the docs. I believe barchart_demo.py is referenced in the backend_driver tests. Also, you should consider running a PEP8 checker just to ensure you don't miss anything.

[gabraganca]

Yeah. Your suggestion seems more reasonable on the farenheit/celsius plot.

So there is already a cleaned version of the barchart? I will check. And also will check about the backend_driver.

[gabraganca]

@tonysyu, just changed the F/C plot. The other is still pending.

@gabraganca What is the state of this?

[tacaswell]

Seems to have install issues with py3 and unicode strings.

[gabraganca]

I had totally forgot about this.

[gabraganca]

Since it has been a long time that I do not work on this, what would you recommend? I should do a rebase and then let the Travis check again?

[tacaswell]

It looks like the F/C demo is good, but the barchart demo still needs some thought/merging with pylab version of the demos.

How about pulling the F/C demo changes out into a new PR which we can get merged straight away and, unless you are willing to put more time into cleaning up the barchart demo, dropping that part?

[gabraganca]

Ok. I will do this now.
