I am trying to figure out why do we use the daspect. I use daspct[1,1,1] and i know it for equal data unit lengths in all directions, but what is the purpose of that?

Hi Sara,
Function ‘daspect’ is used to control the data unit length along each axis. This can help to better visualizing data.
In 3-D scatter chart example given below, setting daspect([1 1 1]) helps better visualize plotted data by making it less cluttered.
X = rand(100,1);
Y = rand(100,1);
Z = rand(100,1);
scatter3(X,Y,Z)
daspect([3 2 1])
Output :
Output with daspect([1 1 1]) :
Also, ‘daspect’disables the ‘stretch-to-fill’ behavior of plot i.e. resizing of plot window doesn’t change data axis aspect ratio so that there is no distortion in plotted data.
Hope this helps!
