C2 = zeros (24,3); for I = 1:3 C2 (:,I) = smooth (count (:,I)); end. Plot the original data and the data smoothed by linear index and by each column separately. Then, plot the difference between the two smoothed data sets.9. You can use arrow from the file exchange. arrow (Start,Stop) draws a line with an arrow from Start to Stop (points should be vectors of length 2 or 3, or matrices with 2 or 3 columns), and returns the graphics handle of the arrow (s). Edit: @Lama is also right, you can use annotation but you need to take into account the plot limits.Currently, matlab only supports 5 line styles (-,-.,--,:,none). And the dash-dot -. and dotted : lines are poor and look like a solid line. There is no neat way to have …

text (x,y,txt) adds a text description to one or more data points in the current axes using the text specified by txt. To add text to one point, specify x and y as scalars. To add text to multiple points, specify x and y as vectors with equal length. text (x,y,z,txt) positions the text in 3-D coordinates. example.
