Thanks for answers!

Yes, I planned to read the database using the Python. I heard for matplotlib, I think it would be the most appropriate for my project. Whether it would be helpful using psycopg lib?- I'm not sure what's the difference, and as I said, I'm complete noob here. I started to read some tutorials and 'Python for beginners', I hope to learn something.
I'm not sure if the data is a simple text file, but in my database...

Hi,

I hope i don't spam this thread, I did not want to open a new thread. I'm a noob here (programming). I need help with creating the program. I need to connect to the database- postgres/postgis (only polylines in there) using Python and pull data from it and plot them (visualize on screen). Can someone help? The easiest way for me would have been to have a code which I could adjust to my database.

Thanks a lot
