Hi Everyone,

Just wanted to say thank you for an amazing first season! I’m looking forward to this truly open-ended challenge where each of you can show off your own interests and skills however you want!


HI All ,

Thanks You guys for these season of challenges.
I Would like to submit something that I created some time ago .
At time din´t see any tool that does it ( Not sure if already exists)
Kind simple :
It take the first firs row and send it the columns headers.


Hi all,

Thank you KNIME team for giving the opportunities to learn something new every single week by Just KNIME It! challenges! I started with Challenge 20 and enjoyed and appreciated it very much.

I was looking for a native gantt chart node but it looks like not available.
I found a component with python code created by the specialists on knime forum but I’m not familiar with python code :sweat_smile: and tried to create something similar without python code.

The output seems to be similar as the one with python code.

I know an error comes with a bigger table and need to learn how to fix it as next step.


My Submission for the Season finale- Challenge 40

I have tried to develop the Indian AQI data- latest real time .

Hey folks, amazing work!

Thank you so much for your participation and I hope we can meet again next year for Season 2! :heavy_heart_exclamation: :nerd_face:


Hello everyone,

I know I am super late but I could not leave the last challenge uncompleted.

Here is my component:

Given a geofence (polygon) and a position, the component will tell you if the position lies inside the polygon or not.
To define a polygon, you can refer to this website. Simply copy the part in yellow and paste it in the column.

Hope it helps someone!

Have a nice day,


Hello everyone,

I decided to simplify the operation that I do quite often when work with Neo4j — creating new node.
So I decided to create a component that will generate and run the query just based on the setting that user provides in a simple dialog.


Merci pour tous les suggestions

Hello KNIMErs
Thanks to the KNIME team for providing all these challenges with new skill leanings every week.

Late submission but, I took this end season challenge to test and learn a few things about components and KNIME dashboard building. The component is supported by Py coding for some calculation and visualization. Besides that, it explains by itself.


PS.- There is a still a bug to be solved, html special characters become corrupted when refreshing the dashboard from button. I will open a new topic in the forum for this issue, then no comments expected here.


Fantastic! Thank you very much for the time you invested here. This is very very cool. :slight_smile:
