Once you set up your clusterization parameters, click the button "Rpt" on the AFNI GUI. On the the popup window, choose the original dataset (input for 3dDeconvolve) as well as your fitted dataset (output from 3dDeconvolve) as auxiliary datasets (click the white triangle button on the popup window). Then click the Plot button for each cluster in the cluster table, and you will get the plots.
However, this won't plot one against the other. For that, you can use 3dmaskave with each ROI (cluster) as a mask, and obtain the averaged time series. Then plot them out with 1dplot, for example.
