is this the proper way to convert your axis and graphs to square microns?

So I want to plot the graph in units of square microns, which I tried to do by calculating the area of each zone in square microns. I tried multiplying the area of each zone in pixels by the conversion factor, which i looked up and I think the conversion factor is the square of the pixel size in microns.

Assuming that the pixel size is 1 square micron:

% Define the pixel size in square microns

pixelSize = 1;

for m = 1 : numfiles

...

% Calculate the radius of each zone in pixels

radius = linspace(0, maxDistance, numZones+1);

area = diff(pi*radius.^2); % Area of each zone in pixels

% Convert area from pixels to square microns

area = area * pixelSize;

...

% Plot the profile

subplot(2, 2, 3);

plot(area, profileCounts, 'LineWidth', 2);

xlabel('Area (\mum^2)', 'FontSize', fontSize);

ylabel('Counts', 'FontSize', fontSize);

title('Counts/', 'FontSize', fontSize);

grid on;

end

So I tried to calculate the area of each zone in pixels using the diff function, which I THINK computes the differences between adjacent elements of a vector then I convert the area from pixels to square microns by multiplying it by the pixel size pixelSize. Is this correct?

Seems ok, assuming that each zone is an annulus and that all zones are concentric.
