Thanks again for a very nice addition to the gallery.

This could be the base for new linestyles (MEP ?):

I mention this just in case: there was some discussion related to line style patterns in #6547 a while ago, and the values that were chosen for the '-', ':' and '-.' line styles are a bit different.

Personally, I think it may be a good idea to add some extra default line styles like this PR suggest. Quite often, I wish there was (at least) a "dashdotdotted" style available.

About the example, I would have 2 remarks:

• it might be confusing to use the names "dotted", "dashdotted" and "dashed" for styles that do not use the default values.
• is it necessary to use plt.xticksand plt.yticks instead of the OO methods ax.set_xticks and ax.set_yticks?

Apart from these, I find the example to be very nice, as it may provide to the users some ready-to-use values for line style patterns, without having them to try a bunch of values on their own (like I often did...)

@afvincent Thanks for the review.

1. The names come from TikZ actually.
2. No reason to use plt.xticks, I need to change that.
3. Dotted /dashed: I didn't know what are the default values so I tried to guess them

Also thanks for the link to the PR. Do you now if there's a way to have round caps in 2.0 ?

Actually it doesn't work with ax.set_yaxis()

Line2D.set_dash_capstyle

There is also a dash_jointstyle

@tacaswell Thanks. I would (personally) prefer round caps by defaults but I imagine it has been already discussed.

Is there anything else to do with this PR ?
