I think YellowPete is right on this one: Had you seen an example of this kind of mapping being done successfully elsewhere that gave you the idea to use it, or is this an idea you've come up with for displaying your data?
Instead of bar charts, you could use pie charts, there are also a variety of other ways of graphically displaying multivariate data, for example wind rose* diagrams or Chernoff faces**. These let the viewer visually pick out anomalous readings easily, but are less good for displaying (or detecting) subtle changes in your data.
