How to draw a "normal" plot in PypPlot?

Question

Python

Hello! I'm trying to draw graphs with PyPlot. So far it looks funny:
But if you look at the points, you can draw a "normal" graph, without intersections
How to make sure that there are no intersections in the lines?

Asked a question and immediately came up with a solution :) The points are not sorted. Need to sort list of points by axes so they match each other
