Refreshdata: refreshdata updates charted data in the current figure to reflect changes in workspace variables
Clf: clf deletes from the current figure all graphics objects
'clear all output' Which coding function?
More see
clear; % Clear workspace variables
More: Clear all: Clears Variables, Scripts and functions Class definitions, Persistent variables, MEX functions, Global variables etc
Alert: Calling clear all decreases code performance, and is usually unnecessary.

@Kalyan, clear all clears much more than just variables. That is why mlint will warn you not to use it. Please edit your question to avoid perpetuating this bad practice.
