Dear Salem,
see the help text of spm_graph.m for the exact meaning of your plots
(the confusingly named fitted/predicted/adjusted/corrected responses).
When you make a plot, your MATLAB workspace contains variable Y (fitted
response, continuous line) and variable y (adjusted data = fitted
response + residuals, dotted line) so you can do the plot yourself with
a direct call to the MATLAB plot function with one of these variables.
You can also select the "Edit plot" option of the Tools menu of the
Graphics window to directly edit anything displayed on it.
Best regards,
Guillaume.
