How do I redraw a picture given to me using its data points that I've found using the curve fitting app?

Hello, I am trying to redraw this picture given to me by my professor. He told me to analyze it by curve fitting. So I did 4 fits and I was only able to get 3 fits into figures (SEM_data_points_figure, fit_poly2_figure, fit_poly3_fig) The last fit when I tried to save it as a figure kept giving me the error 'Index exceeds array bounds'. However, I need to redraw the picture using the data from these 3 fits. I need help please on how I can write code to go about doing this. Because the professor says I need to write code to get the data.
Thank you for the help.
The code below is from the data points from fit 4 which basically has the same data points as the 3 other fits. The data points for all 4 fits are basically the exact same points.
hold on;
%This is to make the D matrix
D=zeros(300,3);
%These are the data points from my fit poly 4 that I made into matrix form
%However, these cannot go into a matrix.
%How do I display these points in a figure?
D(0,0,0)=1;
D(100,0,0)=1;
D(140,0,0)=1;
D(160,0,0)=1;
D(180,0,0)=1;
D(201,0,0)=1;
D(215,0,0)=1;
D(230,0,0)=1;
D(260,0,0)=1;
imshow(D) %I know this can't work because its for a matrix
