Are the built updated pages. I am 👍🏻 to merge as is, but I think it would look a bit better with a thinner lw on the surface? |
|
Thank you for finding and fixing this very old fallout from the mpl 1->2 style change! |
|
@tacaswell Thanks for the feedback.
Agreed, those plots are ugly. However, this is also very strange: It is not how it looks like on my machine locally. How should I fix this? |
|
Do you have any custom rcparams set? The simplest solution is to pass lw to the calls, but we should understand why you get something different locally. |

I did not check whether it's related, but https://matplotlib.org/devdocs/gallery/mplot3d/wire3d.html#sphx-glr-gallery-mplot3d-wire3d-py has a similar linewidth. |
|
It would indeed look better with thinner lines, but then this seems to be the default linewidth considering the width of the other plotted lines in that figure (the ones on the panes)? |

The For comparison I suggest to make the lines thinner (0.8 or even 0.5) and maybe go from black to a dark grey. We already a lot of customization on the |

Done. All green. I do not know how to link the built updated pages here, sorry. They look really nice locally on my machine. |

It's recommended nowadays to use the colormap registry instead of importing from matplotlib.cm:
cmap = plt.colormaps['coolwarm']
You could go even one step further and use the string contour(..., cmap='coolwarm'). Usually, that's the simplest way if you don't need the colormap object itself. Here however, you have the cmap(0) call. I'm tempted to resolve this to an explicit '#3b4cc0' and get rid of the colormap object completely, which IMHO makes the example simpler.
But I'll let you choose whether to go all-string or retrieve cmap from plt.colormaps.

Yes, that cmap(0) is bugging me too. I was considering '#3b4cc0' too, but it is too cryptic. Is there some named blue in the neighborhood?

Since I am green blind, I would like to kindly ask you to please help me out here: If you agree, please suggest a named blue instead of '#3b4cc0'. Thanks!

You can try 'mediumblue' which is slightly darker, or 'royalblue' which is a bit lighter.

Thank you very much for your help. The revised code/plots are here: I went with royalblue. In my opinion, the mediumblue looks too harsh on the filled version of the plot. What should I do next? |
|
Thank you @baharev and congratulations on your first merged Matplotlib PR 🎉 I hope that we will hear from you again! You maybe interested in One of my regrets from the 2.0 default style changes is that while we put a whole lot of effort into the color map and making sure it was OK for color vision deficiencies, we failed to do the same to the default color cycle. |

And I would like to thank you all for your help, patience and constructive feedback. 🙂 I will watch that video this evening, thanks for the info. |
