It is a simple scatter plot and a curve is fit to the data. To achieve the plot read about the following functions:

Load data into MATLAV using xlsread or readtable.
Plot the data by markers using either scatter or plot.
You can fit the curve/ polynomial using poly or cftool.

In my plot will not talk about regreesion or fitting process but little bit more about plot th data with additional text in each layer. I don't know about how to positionin gthe text between each line and why I can't no plot x1,y1 and x2,y2
