uxds[v1].plot(cmap=ux.cmaps.sequential, backend='matplotlib')

uxds[v1].plot(cmap=ux.cmaps.diverging, backend='matplotlib')

Also from the usage example in the overview, it should be something like the following:

import uxarray as ux

uxds[v1].plot(cmap=ux.cmaps.sequential, backend='matplotlib')

uxds[v1].plot(cmap=ux.cmaps.diverging, backend='matplotlib')

The addition to the user guide section also appears to be failing.

How do you think the colors look? @rajeeja @philipc2

The colormaps look great, but I'm wondering if maybe we would like to consider different colors all together for the style of Uxarray?

We still don't have a true package logo. Would you like to sit down together (including @rajeeja too) to brainstorm some ideas for the theme of Uxarray?

For the text of the logo, I was considering something like the following.

For reference, xarray:

It would be nice to put together a style guide for our package, logos, and design. Something like:

I've always liked the idea of this style of logo, which emphasizes the spherical unstructured grid support we provide.

We could also adapt the Project Raijin logo for UXarray, which I think looks quite nice. We could modify the colors too.

I like these colors a lot more than the other ones.

[philipc2]

Here are the colors from the new logo if you'd like to update these colormaps:

Blue:
#016691

Green:
#049390

Gray:
#343741

@philipc2 I really like how these came out.

@philipc2 I really like how these came out.

These are very pretty!

One small nitpick: can you make the blue & green ones start at zero (white)?

[philipc2]

Can you see how a colormap would look if it's a White -> Green -> Blue sequence?

A lot of the sequential ones on mpl appear to start with white.

Oh yeah that would be important!

[philipc2]

Everything looks great here! Once we have the following color maps, it'll be ready!

• Sequential: White, Blue, Green
• Sequential: White, Blue
• Sequential: White, Green
• Diverging: Blue, White, Green

[aaronzedwick]

What do you wanna call this one then?

[aaronzedwick]

• Sequential: White, Blue, Green
• Sequential: White, Blue
• Sequential: White, Green
• Diverging: Blue, White, Green

The blue looks darker to me so I think it makes more sense to go green-blue with the colors.

[philipc2]

Can we also add edges to this plot? Maybe a title would be good too for each.

[philipc2]

These colormaps look great! Thanks for putting them together.
