Hello. I currently have an excel sheet of 0s and 1s. I am trying to visualize an inkjet print where ther 0s say dont print and the 1s say print. I My hope is that I can convert the 30x30 excel file into a plot on matlab where labels the print points with a dot on a graph. How would I accomplish this.

How about
I=readmatrix('yourfile.xlsx');
imagesc(~I)
colormap(gray)
If you don't want an image, then try
[r,c]=ind2sub(size(I),find(~I)); % locate zeros
MrkrSize=36;
hSc=scatter(r,c,MkrSize,'MarkerFaceColor','k');
scatter draws marker area proportional to the marker size parameter, a radius of 6 with the plot() function is same visually as area of 36 with scatter()

Is there any way to edit the size of the squares in the plot. That way I can see what it would look like if i were to print with different size inkjet droplpets?
