Adding Plotnine graphs

[votti]

Hi there, thanks for providing this useful resource!

Half a year ago I was really excited to find https://github.com/has2k1/plotnine , the first really usable ggplot2 implementation in Python. The implementation is so close to ggplot2 that one can even use the ggplot2 tutorials and manual almost 1:1.

The gallery provides many nice examples of the usage: https://plotnine.readthedocs.io/en/stable/gallery.html Maybe it would be helpful to add these examples to the Python graph gallery?

Hi votti, Thanks for this suggestion. I have to study this library more in depth, it looks very promising. Thanks!

[votti]

I just remembered that there is even another repository with plotnine examples: https://github.com/has2k1/plotnine-examples/

I'm reaching the end of the bandwidth I had to update the gallery and did not find time for the plotnine library, so I'm gonna close this old issue :(

Two more usage tutorials for plotnine in case you ever want to revisit this topic:

• https://github.com/cmparlettpelleriti/CPSC392ParlettPelleriti/blob/master/InClass/LectureNotebooks/Visualization%20I--Class%204.ipynb
• https://github.com/cmparlettpelleriti/CPSC392ParlettPelleriti/blob/master/InClass/LectureNotebooks/Visualization%20II--Class%205.ipynb

I'd be interested to contribute plotnine impl. of certain basic figures if there is interest (as measured by the number of thumbs up on this comment).

Hi @ivanistheone, thanks for your comment.

As stated before, I would be very keen to add some plotnine examples to the gallery. I just don't have the bandwidth for it yet.

If you feel like contributing (that would be awesome! 😄 ), it would be cool to have a translation of any of the R graph gallery ggplot2 blogpost in plotnine. The post in the python graph gallery are just jupyter notebooks, so building PRs should be relatively straightforward.

Example: density chart, histogram and so many others..

Otherwise I keep it in mind for when I will have more time on the project!

Is there a contributing guide somewhere?

I'm slowly getting around to looking at plotnine (I'm a beginner, but there are so many examples and this project has nice tooling so I want to try adding some basic charts just to get some practice with it).

I was looking to start with a boxplot, and I see each thumbnail is a link to a notebook:

          <ChartImageContainer
            imgName="33_Custom_Boxplot_color_Seaborn5"
            caption="Everything you need concerning color customization on your boxplot: transparency, palette in use, manual control.."
            linkTo="/33-control-colors-of-boxplot-seaborn"
          />

where the image is in static/graph folder and the linkTo is this notebook, but Q1: how was the image name 33_Custom_Boxplot_color_Seaborn5.png generated?

I'm guessing the 5 is an auto-incrementing, i.e. fifth graphic in the notebook, but where did 33_Custom_Boxplot_color_Seaborn come from?

The notebook has slug = 33-control-colors-of-boxplot-seaborn in the metadata section at the end of the .ipynb json, so that doesn't seem to be it.

Q2: Is there a build system for the notebooks that extracts all the graphics and put them into static/graph?

Any pointers and tips for getting started will be much appreciated.

Hi @ivanistheone @votti

I'm back with bandwidth to work on the gallery.

• I took another look at plotnine and it definitely makes sense to add examples to the gallery.

• I am currently documenting the process to add new examples in the repo Wiki

• Q1 -> The images you see in the gallery are hand-made.

• Q2 -> NO, I do it by hand

Thanks!

Closing now as we're in the process of adding examples with @JosephBARBIERDARNAL
