You could manually create the bins yourself fairly easily.
The issue you will have is that the Bin sizes change depending on what variable you are displaying. You may need to do something that includes using a table calc to find out what the max is for that variable, divide it by 10, say, then use that for the bin size.
Could end up a bit tricky.
The other option is to create as many charts as you have variables, then hide all but one at any time.
