I have two set a data x from 0 to 6.25 and y from 0 to 3.5e6. I want to mirror the plot (x,y) with respect to a specific x-axis (x=6.25). and plot(x,y) this time for x from 0 to 12.
My set of data

% put back the data in ascending order (simpler)
[x,ind] = sort(x);
y = y(ind);
% create mirrored data
xx = -x(2:end)+2*max(x);
yy = y(2:end);
plot(x,y)
hold on
plot(xx,yy)
