I have a series of repeated data points that i am trying to fit with a skewed curve. In the graph I am showing one set of the data points which are in blue. The black hand drawn line is the kind of fit i want for my data. I want my fit to be a curve like the one drawn, not a combination of two linear functions or a sawtooth. I have included the data points in text files. Thank you.

The wobble is because i am not very good at drawing a straight line but the intent was for that line to be straight. You are right, the model that i want should be almost a straight line on the left side, unfortunately i do not have a model function, i am trying to built a model based on this data so i do not have the form, I am just trying to fit the data. Thank you.

My suggestion would be a hyperbola, but rotated.

Thank you for the suggestion. I did try that but unfortunately it does not give me the curved shape i want, it looks more like a combination of 2 linear fits (one for the sloped line on the right and another one that is almost straight for the left side).
