It depends how you use them i think.
like I use volume histograms to help me see when alot of volume is going through a particular range of prices - for me, that is useful and tangible information about what is happening in the market.
I also use graphs to help me keep track if where we are now in relation to where we were before. sounds stupid, but i do like to know where we are in terms of yesterdays high and low etc...
Both of these bits of information you can take directly from the tape, but it requires a great deal of concentration. There is now the technology to do that for you, so I think it prudent (in terms of trader resources) to apply it.
But there are other ways of looking at the information from the tape, such as by plotting bar charts and then applying indicators, or looking for patterns in the tape. This is what I think most traditional TA trading is about (entry here, target here stop here) and I think trading from charts in that way is a little misguided.
