Dear Salem:
The timeseries are not stored in SPM.mat, which contains the details
of the analysis. To plot a time series you have to select the voxel
you want, extract the data from the images, and then adjust the time
series for confounds, etc.
For an example of how to extract the timeseries see spm_regions.m.
For an example of how to extract the timeseries and plot it see spm_graph.m
