lego plot with weights

Dear ROOTers,
I have a TTree containing a.o. data for calorimeter cells.
A cell is specified by a row and column number (the usual matrix geometry)
and contains some signal.
To view an event I would like to plot row%column in a lego plot with the
signal as weight (= height of the bin).
How can I achieve this ?
The PAW equivalent would be : nt/plot 999.row%col signal

Within ROOT I tried : (h999 is my TTtree)

h999.Draw("ROW:COL:SIGNAL","EVENTNO==5","lego")

but the result is a 3d plot but not in the usual LEGO format, so that I
can't investigate the various signal heights from it.

Cheers,
Nick.
