Week 4 

I really enjoyed the learning journey.

Thanks a lot!

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.

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 🙂

@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.

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].

6,170

Hi Vitaliy,

 

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

@gphadnis2000 :

What I meant was that your result showed this:

VitaliyR_0-1680186375972.png

 

while it should show that:

VitaliyR_1-1680186445272.png

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

6,076

Understood the issue it small code change.

Updated link is below.

Thank you for your submission @SaiNithesh_Gajula 

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.

6,118

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

Thanks @f1se4 

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

No doubt!!!

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

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 🤓

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

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 

5,817

Hej Vitaliy,

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

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