Add documentation for the different seriestypes

[dlfivefifty]

I couldn't figure out how to use quiver, and it doesn't seem to be in the docs.

Here's a usage: #262

In short, the quiver seriestype expects you to pass in velocity vectors using the quiver attribute (with aliases: add_aliases(:quiver, :velocity, :quiver2d, :gradient)

You could pass in a 2-tuple (u,v) for vectors u/v, or you could pass in a vector of 2-tuples for each point. Final form:

quiver(x, y, quiver = (u, v))

Would it be possible to add a page to the docs with examples for every linetype, and a plot of the output? Whenever I need something its a bit of a hide-and-go-seek game to figure out the name of the linetype (I don't remember how I figured out quiver) and the usage.

I'm more than happy to help by making a template that has the cases I already know.

Yes this is one of the last things from the documentation meta-issue. I
just haven't gotten to it yet. Any help is appreciated!

Could there be an alias vector_field for quiver?
I find the name quiver confusing and un-discoverable, especially for non-native speakers.

Does quiver works with 3D vectors? I am trying to naively call quiver(x,y,z, quiver=(u,v,w)), but it doesn't work. Documentation would be helpful.

[mkborregaard]

Agreed

It is not just quiver - there is no general documentation for the different seriestypes. I would say opening a seriestypes tab on the plotdocs with pages for each category of seriestypes ("histogram-like", "scatter-like") is a high priority for documentation. All it requires is for someone to take the time to write them.

It is a little bit surprised to me that this issue have not been alleviated since 2016.

I am confused about why quiver is an function like plot but only appear in Series attribute. I can’t find any clue in the documentation.

An example can tell a thousand words. To make some progress,I suggest that it will be better if
an example illustrating the usage of quiver and some useful associated attribute like aspect_ratio=:equal in Example section and so on.

BTW,
In fact, I searched the documentation for an entire night and I couldn’t find a figure or a description about how to draw a vector.

I search with keyword “vector”, “vector field”, “arrow” since I did’t even know the word quiver beforehand.

Not until I gave up and google it, I thought that Plots.jl does not support this feature.

Fixed.
