Interestingly, the default window size for the 'sgolay' smoothing method in the smoothdata function generates smoothed data that is indistinguishable from the original data in this case.
Below, I've made a slight modification to the answer I gave to your previous question (found here):
I added the window size optional argument to the smoothdata call below. Adjust as desired. Or, experiment with other smoothing methods. See the link above to the documentation.

plot(data(:,1), data(:,2))
hold on
window_size = 8; % <<< experiment with adjusting this to get results that you like
sm_data = smoothdata(data(:,2), 'sgolay', window_size); % save the smoothed data
plot(data(:,1), sm_data)

Also, please don't close questions minutes after posting them. Give people a chance to answer them.
