How to extract numbers from an image?

Question

Python

Hello!
I fell into a creative stupor, and the deadline is just around the corner))
There is a small image:

You need to extract all the numbers from it (I think to use tesseract for this), but the whole problem is that these are the remains of a line chart, and you need to pull them out in the appropriate sequence (starting from the bottom left).
I would really appreciate it if you could give me some ideas. Thank you.
