Weird 'turns' and discontinuous lines

[o7n]

My graph looks like this

How can I avoid the line going 'backwards' and making that nice round turn "to the left" ?
My data is below. The data points are not evenly distributed so I understand why this is happening. I just want it to stop from happening.

No weird configuration. I just set min_y and max_y to some values closer to the max and min values to show the problem.

Related: is there a way to make data points always visible?

Another example:
