Hi Baris,
  You can use the EEGLAB function cbar.m.  For example:

dat=EEG.data(:,100,1);
figure; topoplot(dat,EEG.chanlocs); cbar('vert',0,[-1 1]*max(abs(dat)));

My attached function sig_topo.m shows how to do things like add labels
to the color bar and to mark significant electrodes on the topography.
 You might be able to modify it to suit your needs.
     cheers,
       -David
