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.

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,
Raffaello

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.
