OK, may be I am not clearly described what I am trying to do ...
So I think it might be useful to have an option in TC which would be
generate classes graph in plot format but keep the same text info as it
is printed on console by default. I just think to re-use the existing
code which prints that text info to console but use it for plot
generating. Do you think that this not right thing feature to be in TC
and it might better to have this separately from TC ?

Thanks,
