Good first issue - notes for new contributors

This issue is suited to new contributors because it does not require understanding of the
Matplotlib internals. To get started, please see our contributing
guide.

We do not assign issues. Check the Development section in the sidebar for linked pull
requests (PRs). If there are none, feel free to start working on it. If there is an open PR, please
collaborate on the work by reviewing it rather than duplicating it in a competing PR.

If something is unclear, please reach out on any of our communication
channels.

Good first issue b/c minimally it's adding one string petroff10 to the appropriate listing of colormaps in each of the pages listed above.

But we added these as color sequences not as categorical color maps.

But we added these as color sequences not as categorical color maps

For some reason I thought we'd moved all the categoricals to color sequences, but if not then this issue should be to create user documentation/ a new user guide page for the color sequence registry and using it b/c that doesn't really exist.

It's still an ok first issue b/c it's fairly standalone -> new page in colors section of user guide -> but more work.

@story645 Can you either edit the initial post or leave a comment with details about what you have in mind?

I think we made all of the discrete color maps available as sequences, but did not remove them as color maps. With petroff10 we did not also add it as a colormap (maybe someone will ask for that, but I think we should hold off on doing it until there is actually a demand).

is this issue still open can i work on it?

Yes, this documentation hasn't been created yet and you're welcome to create it.

May I know what is petroff10

May I know what is petroff10

'petroff10' is the matplotlib name for the new color Petroff color sequence and how it is accessed in code.

Hey, is the issue still open, would love to contribute?

Note that issues don't get assigned or claimed: https://matplotlib.org/devdocs/devel/contribute.html#work-on-an-issue

So go for it. 👍 Though reading the contributing docs (https://matplotlib.org/devdocs/devel/contribute.html) is a good first step.

I was trying to set up a dev environment for matplotlib. Finally, figured it out: had to switch from Windows to Linux. So, I'll working on this issue now.

Is the issue still opened? I want to contribute to it

@hwii-florescent Yeah, I worked on the first task. You can get started on the second task:

add a page explaining the color sequences to https://matplotlib.org/devdocs/users/explain/colors/index.html

I am willing to take on the second task. Could you provide more context on what exactly needs to be done?

Here's my understanding.

The page the second task links to has this in its description

Colors

Matplotlib has support for visualizing information with a wide array of colors and colormaps. These tutorials cover the basics of how these colormaps look, how you can create your own, and how you can customize colormaps for your use case.

For even more information see the examples page.

As of now, the page doesn't explore the color sequences — as in how you can customize the color maps and make your information more accessible by using different style sheets.

So, if we have a separate page for that, it would be helpful to Matplotlib users.

That's all I know.

Hello, is this issue completed yet? Am I able to work on it as my first issue - maybe finish off what others left if its still open?

@u7228810 Yes, the second task hasn't been attempted yet.

That said, if it's your very first contribution, I would suggest starting with a difficulty: easy task.

we added these as color sequences not as categorical color maps

FWIW I'm clueless on the difference, I thought that the listings on this page were exhaustive! https://matplotlib.org/devdocs/users/explain/colors/colormaps.html

Unclear to me how to use this new coloring without changing the whole style sheet.

We have both

• colormaps in the ColorMapRegistry mpl.colormaps / plt.colormaps: mapping a numeric interval [0, 1] to colors.
• color sequences in the ColorSequenceRegistry mpl.color_sequences / plt.color_sequences: named lists of colors

Example usages:

ax.set_prop_cycle(color=plt.color_sequences['petroff10'])

ax.stackplot([0, 1], [[0, 1], [0, 2], [0, 3]], colors=plt.color_sequences['petroff10'])

@ammar-quzi Hello does Second task still open ?? pls let me know
am looking for good first issue.

@SHRISHTISHUKLA-0 Yes, the second task is still open.

"add a page explaining the color sequences to https://matplotlib.org/devdocs/users/explain/colors/index.html"

Color sequences are named lists of colors that can be used for style sheets, cycler objects and as lists of colors. colors/index is the section of the docs that explains colors and it's missing a page on sequences.

If you've never worked with color sequences or don't see a need to, then you may not have the context necessary for writing this documentation.

hello I think that I can able to solve this is but here I can't able to link PR why?

@SHRISHTISHUKLA-0 Yes, the second task is still open.

please tell me why I am not able to get PR link after push ??
its showing error ( remote: permission to matplotlib/matplotlib.git denied to SHRISHTISHUKLA-0 fatal: unable to access 'http://github.com/matplotlib/matplotlib.git/'.The requested URL returned error: 403

what should I do now??

The error message indicates that you are trying to push to matplotlib's
repository rather than your fork. Make sure you follow the developer

ooh thank you as firstyear student first time I'm contributing in open sources and pr that's why I having lot of doubts.
