Thank you for your comment. You are right, the graph should have a negative slope. I made the correction.

I might be wrong (I hope not..) but from your graph I see the transfer function:
Vout = Vin + 2.5

Since you followed your demonstration using the equation Vout = -Vin + 2.5 it might just be the graph, where I would expect to see a line from top left corner to bottom right corner.

Best,
Adrien

That transfer function shows that the amplifier has reactive elements, like capacitors, besides resistors. What I showed in this article is the DC calculation of a circuit, starting from its linear transfer function. Discussing the function you pointed to, takes more than just this comment space. Since you mentioned it, I will most likely write an article about it. Check back from time to time or subscribe to this website.

Is there any way to start from here?

You have to give me more details to help you. A bi-dimensional graph has 2 axes. The sequence of binary numbers is on one axis. What is on the other? For example. if the sequence of binary numbers comes from an ADC, on one axis there are these numbers, and on the other axis the ADC input voltage. You can see such a graph in this article, An ADC and DAC Integral Non-Linearity (INL), figure 1.
