understand that BARCOORDS is an output parameter, rather than an input
one, hence I don't see how you can use BARCOORDS to determine the
placement of the bars on the X axis.

You are not going to be able to do anything about the ticks, but maybe
something like this will work for you:

tickNames = StrArr(5)
FOR j=0,4 DO tickNames[j] = StrTrim(j*10,2) + '-' + StrTrim(j*10+10,2)
cgBarPlot, findgen(5)+1.0, barnames=ticknames

Cheers,

David
