MATLAB: How to plot different figures from the same matrix

plot

Hi!
I have a matrix with 1376×3 dimensions. First column is the day, second the time and third my measurements. The matrix is:
 8  7.56  316
 8  8.45  319.56
 8  10.78 317.4
 9  12.76 323.98
 9  14.27 356.89
 10 13.45 346.12
 10 14.2  312.43
and so on, until the day 365. (some days are missing).
I want to plot the second and third columns for each day separately.
Any ideas?
Thank you!

Try this
D = [
 8  7.56  316
 8  8.45  319.56
 8  10.78 317.4
 9  12.76 323.98
 9  14.27 356.89
 10 13.45 346.12
 10 14.2  312.43]
uniqueDays = unique(D(:,1));
numberUniqueDays = numel(uniqueDays);
for nd = 1:numberUniqueDays
    indexToThisDay = D(:,1)==uniqueDays(nd);
    figure
    plot(D(indexToThisDay,2),D(indexToThisDay,3))
end
