Week 4 

I really enjoyed the learning journey.

Thanks a lot! 

[Vitaliy-R]

You were fast, not long after this week's challenge was published!

But I see that in the end, you resolved the problem with

counter_clock=False

by simply deleting that part 🙂

It's one of the attributes from **kwargs of https://help.sap.com/doc/cd94b08fe2e041c2ba778374572ddba9/2022_4_QRC/en-US/hana_ml.visualizers.html#... that is taken from Matplotlib's https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.pie.html#matplotlib-pyplot-pie

You just need to correct `counter_clock` to the correct keyword.

[sourabh3ss]

Actually I didn't find any documentation for this argument in HANA-ML documentation, so I thought it is a invalid argument. I should have checked the matplotlib as well.

Updated the link 🙂 

[Vitaliy-R]

@sourabh3ss , 

I see that you replaced plt.show?  or bikes_hdf.select? with executable statements, while I wanted participants to run with those question marks to show how to quickly check a signature of the Python object.

FYI, I added an explicit description now to the notebook:

 Execute the cell below as-is (with a question mark at the end) plt.show? see the help for the method.

Week 4 link.

Absolutely enjoyed all weeks with lot of learning and cool stuff in pandas and visualisation

[Vitaliy-R]

Thank you @gphadnis2000 I am glad to hear you found some cool stuff and have enjoyed the experience.

In your submission, I am missing `Bikes_Rented` line on the plot of the result of the cell [42].

[gphadnis2000]

Hi Vitaliy,

I could able to see 'Bikes_Rented' plot as per week 4 sample notebook.

[gphadnis2000]

the above is screenshot of my github upload from link mentioned for week4.

[Vitaliy-R]

@gphadnis2000 :

What I meant was that your result showed this:

while it should show that:

There is one issue I see when you corrected the code in that cell 🤓

[gphadnis2000]

Understood the issue it small code change.

Updated link is below.

Hello,

Here is my Week 4 submission.

Regards,

Sai Nithesh

[Vitaliy-R]

Thank you for your submission @sainithesh 

There were two cells with the `?` at the end of Python statements, and I had asked to execute them as-is, ie. with those question marks at the end to see how that displays handy help.

[sainithesh]

Hi @Vitaliy-R ,
I have modified them accordingly and execute the notebook. Also pushed the same to the github.

Regards,

Sai Nithesh

And now week 4.

week 4 

Beautifull one! 🙂

Sergi

[Vitaliy-R]

Thanks @f1se4 

Indeed data viz can be beautiful! But can be ugly as well 😉

[f1se4]

No doubt!!!

Mmmm I have seen here some pie graphs.... hahahahah 

Sergi

[Vitaliy-R]

Guilty as charged, I am not a strong opponent of pie charts @f1se4 

That why I mentioned "data scientists love to hate pie charts" in the notebook 🤓

[f1se4]

XDDDDDDDDDD

Thanks for sharing these 4 sessions of initial insights into the hana_ml library. I also enjoyed the best practices for chart design - that could be a nice course on its own right when the hana libraries are available. (For now I could not even get a scatter_plot running without error.

https://github.com/obinym/sap-community-developer-challenge-eda-hana/blob/main/notebooks/challenges/...

Also looking forward to get my hands on the learning model part of the library in the future.

Sessions were very well prepared. Kind Regards, Oskar

[Vitaliy-R]

Thank you for trying other options too @obinym !

Challenge submission:

week 4 

I learned a lot with each submission of this challenge. The last one was the best! Thank you @Vitaliy-R , it has been a great opportunity to enhance my skills and get more familiar with EDA with SAP HANA and it's capabilities. Looking forward for the next one!

Best regards,
Rafael

[Vitaliy-R]

Thank you @rcaziraghi 

It’s great for me to hear participants learned something new!

My week 2 submission.

[Vitaliy-R]

@miyasuta Thank you, and it seems to be week 4, not 2, submission 🙂

[miyasuta]

My mistake! Indeed it is week 4 submission.

Thank you for joining @richa_dwivedi and trying different things.

This month my teammate @dan_wroblewski started another developer challenge: https://blogs.sap.com/2023/03/30/you-think-you-know-sap-build-take-our-challenge/ and I hope you find time to join it too.

[Vitaliy-R]

Cześć, Pawle! Last two lines in the notebook you submitted are not executed. I see you fixed the error in a code, but notebook is saved with the error message 

[pawelwiejkut]

Hej Vitaliy,

indeed, idk what happened. It should be fixed now 🙂 And thank you for this challenge !

[Vitaliy-R]

I see you added Seaborn too. What are your primary motivations for using seaborn instead of matplotlib, if I may ask out of curiosity?
